Façade lighting plays an important role in shaping how buildings are perceived after dark, while also supporting the safety and usability of outdoor spaces. For residential, hospitality and commercial environments, wall luminaires must deliver not only visual impact, but also durability, efficiency and installation flexibility. When specifying exterior wall lighting, professionals must consider a number of factors, including light distribution, colour temperature, glare control, environmental protection and long-term reliability. Increasingly, there is also demand for solutions that offer adaptability on site, allowing lighting effects to be fine-tuned to suit different architectural styles and changing project requirements. To meet these needs, LEDVANCE has expanded its outdoor luminaire portfolio with the URBAN WALL VARIO – a highly versatile, decorative wall light designed to combine architectural aesthetics with robust outdoor performance. URBAN WALL VARIO is designed to provide upward, downward or combined up-and-down light emission, enabling specifiers and installers to accentuate façade textures, highlight entrances and create depth and visual interest across building elevations. Interchangeable reflectors are supplied as standard, allowing beam angles of 30° for more focused accent lighting or 55° for a wider, softer distribution, making it easy to tailor the lighting effect to the application. On-site adjustability allows lighting effects to be fine-tuned during or after installation, with discreet controls enabling changes to light direction, colour tone and output without affecting the clean external appearance. This allows more sensitive integration of lighting with different façade materials and architectural styles. Built for long-term outdoor use, the luminaire combines robust construction with protection against weather, impact and temperature extremes, making it suitable for a wide range of exterior settings. High durability and extended service life also help to reduce maintenance demands over the lifetime of the installation. Durability remains just as critical, especially in exposed outdoor locations where luminaires must withstand weather, temperature fluctuations and physical impact over many years of operation. URBAN WALL VARIO is rated IP65 for protection against dust and water ingress and IK08 for impact resistance, with a robust aluminium housing and C4 corrosion protection to ensure long-term performance in challenging external environments. A long lifetime of up to 100,000 hours (L70/B10) further reduces maintenance requirements and supports lower whole-life costs. From an installation perspective, efficiency and adaptability are also high on the priority list. With dual cable entries for through-wiring, snap-in connectors and a mounting design that allows installation in either orientation, the luminaire accommodates varied wiring approaches and simplifies coordination on site, helping to reduce installation time on fast-paced projects. For projects requiring intelligent control and seamless integration with building management systems, URBAN WALL VARIO is also available with DALI-2 control gear. These versions enable precise digital dimming, individual addressing and flexible grouping zones. Head of Project Sales at LEDVANCE UK – David Goddard adds, “Architectural lighting should enhance a building’s character while standing up to the realities of outdoor use. Our aim with URBAN WALL VARIO was to create a solution that supports creative façade lighting while also addressing the practical challenges faced by designers and installers on site.” Supported by LEDVANCE’s technical guidance and project support services, the URBAN WALL VARIO range is positioned to help professionals deliver exterior lighting schemes that balance visual quality, reliability and ease of implementation across a wide variety of outdoor applications.  For more information, contact LEDVANCE UK.

Transformers are the backbone of reliable power for utilities, industrial sites and large construction projects. When a substation upgrade or emergency replacement is on the line, two things matter greatly — price and how fast a supplier can deliver. In a tight North American market where lead times stretch into months, buyers need vendors with real inventory, transparent pricing and logistics muscle to hit commercial operation dates. What to Look for in a High-Quality Transformer Procurement teams should benchmark manufacturers on compliance, engineering depth, life cycle cost and delivery readiness.  Look for IEEE/ANSI compliance, UL listing where applicable and documented factory test routines. Ask about core steel grades, winding design, tap changer options, and monitoring packages like dissolved gas analysis, bushing monitors and hot-spot temperature sensors for predictive maintenance.  Pricing ranges in the United States vary by spec and size. For example, a common pole-mounted distribution transformer will cost less than a typical three-phase pad-mounted unit for commercial service. At the fleet level, the total cost of ownership comes down to efficiency class, cooling design, fluid choice and warranty support.  Why is fast delivery a challenge for many transformer manufacturers? According to Wood Mackenzie, U.S. demand for power transformers has surged 116% since 2019, while demand for distribution transformers increased 41% — driven mostly by rising electricity use and grid projects.  The same research agency expects 2025 supply deficits of about 30% for power transformers and 10% for distribution units. Imports are expected to supply approximately 80% of U.S. power transformers and 50% of distribution units in 2025. These dynamics push prices up and extend lead times, which is why suppliers with inventory or accelerated programs stand out.  10 Top Providers of Affordable New Transformers Large power transformers average $500,000 to $3 million, depending on voltage class, rating and options. That capital outlay is tough for many smaller utilities and Engineering, Procurement and Construction (EPC) teams, so providers that blend competitive pricing with quick ship capacity reduce schedule and budget risks.  1. Sunbelt Solomon Sunbelt Solomon is one of North America’s most visible transformer suppliers with nationwide service coverage and a strong inventory. The company maintains Quick-Ship stock for pole-mount and pad-mount distribution units, and it highlights immediate shipment on select models.  Sunbelt also supplies new components alongside surplus and reconditioned options, which helps match budgets and schedules across different project scopes. Products include liquid-filled and dry-tape padmounts, along with field services for commissioning and maintenance. For buyers racing against a deadline, the quick-ship landing page and “available for immediate shipment” options help preserve project timelines. Coverage is national through multiple field teams and facilities.  Sunbelt Solomon is frequently used for emergency replacements, capital upgrades and temporary bypass service during substation work. Quotes often include freight timing and coordination with site receiving, so crews can plan with confidence.  2. GE Vernova For engineered power transformers, GE Vernova Grid Solutions covers everything from medium to ultra-high voltage with ratings from 5 mega-volt amperes (MVA) to 2,750 MVA, including high-voltage direct current (HVDC) and phase-shifting variants. Designs emphasize digital monitoring and high-efficiency cooling to cut losses.  While large units are typically made to order, GE Vernova announced recent U.S. factory investments aimed at capacity growth and delivery performance — welcome news for schedule-sensitive projects. Buyers seeking utility-grade generator step-up or auto transformers will value the breadth and installed base of these products. Engineering teams can support custom impedance, loss and noise targets for sensitive sites. A broad installed base with utilities and independent power producers helps procurement benchmark life cycle performance. 3. ELSCO Transformers ELSCO Transformers focuses on the emergency replacement of pad-mount and dry-type distribution transformers, offering fast delivery through its Quick-Ship program. If the right unit is in stock, it can ship within 24 to 48 hours.  ELSCO says it maintains 95% availability of dry-type units with popular voltage ratings, such as 2400, 4160, 12470, 13200 and 13800. It also runs a rapid response team for outage situations. This offering is suited for plants, campuses and municipalities that need a fast, like-for-like medium-voltage unit.  Stock is concentrated on common kilovolt-amperes (kVA) sizes with standard accessories to simplify interchangeability. Clear datasheets and test reports can speed up internal approvals during emergency outages.  4. Daelim Transformer Daelim Transformer manufactures ANSI/IEEE-compliant distribution and substation transformers and has taken steps to shorten delivery times to U.S. customers. In mid-2025, it announced the pre-positioning of over 500 UL-listed pad-mounted transformers across the country for urgent applications, targeting data centers and high-load sites.  For standard pad-mount ratings, Daelim also markets swift production timelines and expertise in North American standards. This mix of U.S.-stocked inventory and factory capacity can help hit tight in-service dates while keeping unit costs competitive. Units arrive configured with U.S. practices, including tamper-proof cabinets and common bushing layouts. Buyers who standardize a narrow set of ratings often use Daelim to stabilize costs across various projects.  5. MGM Transformers MGM Transformers is a major U.S. distribution transformer manufacturer with an explicit expedited program. The Bull Rush program offers fast solutions in as little as five working days on select models — backed by a broad catalog that includes liquid-filled and dry-type units for commercial and industrial applications, battery energy storage systems, and renewables. For projects with near-term energization, Bull Rush is a concrete path to reduce schedule risk without sacrificing spec compliance.  Requests for special taps or enclosure variations can be reviewed under the expedited window case by case. The company’s North American footprint helps reduce shipping uncertainty during peak seasons.  6. Evernew Transformer Evernew Transformer is a long-standing Chinese transformer manufacturer exporting oil-filled and dry-type units worldwide, including Canada and the U.S. Its portfolio spans pole-mount, tabletop, substation and power transformers up to high-voltage classes.  Buyers often consider Evernew for factory-direct pricing on new builds, then plan around freight to meet their schedules. For U.S. projects, confirm UL and IEEE/ANSI alignment on the exact model and build, taking customs lead time into account when comparing the landed cost against domestic quick-ship options.

More than half (59%) of UK heating engineers are either already or likely to work with other companies to develop heat pump competencies, according to heating and hot water solutions provider Baxi’s fourth annual Installer Skills Survey. Despite this interest in being prepared, a lack of consumer demand remains the number one barrier to heat pump uptake – with 60% of installers citing this as the main barrier, highlighting the challenge of converting installer interest into real-world installations. The 2025 Survey showed that attitudes of some segments of the heating engineer population are becoming more sceptical of heat pumps and towards net zero more broadly, reflecting the increasingly divisive narratives on the topic from across the political spectrum. The survey – conducted with green supply chain consultancy Talan (formerly Gemserv) – gathered responses from almost 400 installers, making it the most comprehensive snapshot of UK installer attitudes to heat pumps to date. Confidence growing as training makes its mark The study found that 59% of installers are either already developing the skills to fit heat pumps or intending to do so within the next few years.  As the majority of installer operators are either sole traders or very small businesses with just two or three employees, the trend is to partner with other companies that can provide complimentary services, such as system design, installation support or financing. The number of installers citing a lack of training as a barrier has fallen by 18 percentage points compared with 2024, suggesting that industry investment in training is beginning to pay off. Baxi alone has seen over 1,000 installers attend its own heat pump training courses over the last 12 months. When asked what drives them in their work, heating engineers most frequently cited providing a good service to customers (85%), solving technical problems (62%), and getting things right from a technical perspective (50%). According to Baxi, this sense of professionalism partly explains why some installers hesitate to recommend new technologies until they feel fully competent. “Installers clearly want to do the right thing for their customers,” said Ian Trott, Head of Training at Baxi UK. “Many take pride in their technical ability and won’t compromise on service until they’ve built real hands-on experience with the technology. Training for a qualification is one thing – but training for competence is what’s really needed to move the needle on installer engagement.” Hybrids seen as a practical bridge The 2025 survey also found that 35% of installers have or would be somewhat or extremely likely to move to fitting heat pumps as part of a hybrid system, where a heat pump works alongside an existing combi boiler, rather than as a full heat pump only replacement.  Unlike a stand-alone heat pump system, hybrids typically do not require a water cylinder making the installation lower cost, quicker, less disruptive and with less complexity for the installer. “Hybrids can be a powerful transitional step,” Trott said. “They are often more attractive to installers because they’re easier to fit, and to customers because they require less cost and disruption. Research shows a well-installed hybrid can cut a home’s heating carbon footprint by around 70% a year or more. Supporting hybrid options would give more installers valuable real-world experience and help homeowners see the benefits earlier.” Paperwork and demand still holding the sector back While attitudes to heat pumps have shifted positively, consumer demand is developing more slowly. Although many households continue to prefer a straightforward like-for-like boiler replacement, 2024 was still a record year for UK heat pump sales. Almost half of respondents – 46% – named the paperwork involved in government schemes as a major obstacle to installing heat pumps, saying it slows down projects and can deter customers from making the switch. To help ease this burden, Baxi will launch its own MCS Umbrella scheme later this year, designed to reduce the administrative workload for smaller businesses and sole traders. The company has also expanded its hands-on training programme and increased online and video-based educational resources produced at its Warwick Solutions Academy. Generational divide and industry dynamics A recurring theme in Baxi’s annual surveys has been a generational divide in attitudes to retraining. Installers approaching retirement are generally less inclined to invest in developing new skills, while those earlier in their careers are more open to diversifying their expertise. The survey also noted that a large proportion of UK heat installers work either as sole traders or in very small teams. This structure can make it more difficult for them to take time out for training or to manage the additional paperwork that often accompanies low-carbon installations. Many respondents said they expect to collaborate or partner with other service providers to meet future demand for clean heat technologies. “These findings show that despite some hardening of opinions most gas boiler installers aren’t dogmatic about technology and just want to do a good job for their customers. Many installers are preparing for the future, with plans to prepare for the uptake of heat pumps and develop their skills. As a result, more installers are comfortable talking to their customers about energy efficiency and fewer say that training is a barrier than in last year’s study. It shows that the work the sector is doing to encourage training is working,” said Will Taylor, Principal Consultant at Talan. The role of installers in decarbonisation Home heating is responsible for around 18% of the UK’s carbon emissions, and approximately 85% of households still rely on natural gas boilers. As the transition to cleaner heating accelerates, installers are expected to play a central role in guiding customers through their choices and in ensuring new technologies are fitted competently and to a high standard. Almost 400 installers took part in this year’s survey, which was conducted in July and August 2025. Building, Design & Construction Magazine | The Choice of Industry Professionals
