DLC 5.1+ commercial LED high-bays, architectural troffers, wall packs, Type A/B/C T8 & HID retrofit lamps, Advance ballasts, Jefferson control transformers, Edwards life-safety signaling, and Electromode electric heaters.
As a verified 2026 NHSaves Participating Commercial Lighting Distributor (serving Eversource NH, Liberty, NHSaves, and Unitil territories) and Massachusetts contract supplier, we stage RAB Lighting, Keystone, Satco, Sylvania, Metalux, and Lumark luminaires with field-selectable wattage and CCT.
Immediate counter cross-referencing for multi-tap ANSI M57/M58/M59/S51/S54 HID core-and-coil ballast kits, T8/T5HO electronic ballasts, Jefferson Electric buck-boost and industrial control transformers, and hard-to-find UV, halogen, and miniature indicator lamps.
Industrial Edwards Signaling AdaptaHorns, AdaptaBells, and strobe beacons, UL 924 90-minute emergency egress battery units and SLA replacement batteries, plus Electromode (Electramode) cast-aluminum grid heaters and Cadet commercial wall heaters.
Selecting the right retrofit path prevents tombstone arcing, ballast incompatibility, and disqualified utility rebates.
| Retrofit Classification | Wiring & Driver Architecture | Input Voltage Options | Key Advantages & Limitations | Best Institutional Application |
|---|---|---|---|---|
| UL Type A (Plug-and-Play T8/T5) | Operates off existing instant-start or programmed-start electronic ballast | Ballast Dependent (120–277V) | Zero rewiring labor; however, when the aging fluorescent ballast eventually fails, the lamp goes dark | Rapid relamping of newer classrooms/offices with recently installed NEMA Premium electronic ballasts |
| UL Type B (Ballast-Bypass / Direct-Wire) | Internal driver in tube; line & neutral wired directly to shunted/non-shunted G13 sockets | 120–277V Universal (Single or Double-Ended) | Permanently eliminates ballast failures and ballast parasitic watt draw (saving an extra 3–5W per lamp) | Permanent maintenance reduction across municipal buildings, mills, garages & 24/7 corridors |
| UL Type A+B (Hybrid Dual-Mode) | Works on existing electronic ballast today; switches to direct 120–277V line voltage when ballast dies | 120–277V Universal | Allows immediate installation now and phased ballast removal later without changing the lamp | Large school districts and hospital campuses standardizing on a single stocking SKU |
| UL Type C (Remote External LED Driver) | Low-voltage DC LED tubes powered by a dedicated 0–10V dimmable external LED driver | 120–277V or 347–480V | Highest DLC 5.1 efficacy, smooth 0–10V dimming to 1%, and seamless occupancy/daylight sensor integration | Rebate-maximized office, library, and university classroom retrofits requiring zoned 0–10V dimming |
| HID-to-LED Mogul (E39/EX39) & High-Bay | Ballast-bypass 100–277V / 277–480V high-lumen corn-cob lamp or full UFO / Linear High-Bay fixture | 120–277V & 277–480V 3-Phase | Replaces 175W, 250W, 400W, and 1000W Metal Halide / HPS with 60–75% watt reduction and instant restrike | Gymnasiums, DPW truck bays, manufacturing high-bays, parking lot shoeboxes & perimeter wall packs |
Many New England manufacturing plants, paper/textile mills, and municipal wastewater facilities run high-bay lighting and unit heaters directly off 480V 3-phase delta or 277/480V wye feeders.
Connecting a standard 120–277V LED driver to a 480V circuit causes immediate catastrophic driver failure. Our Lowell counter stocks dedicated 277–480V high-voltage LED high-bays, wall packs, and step-down autotransformers, plus Jefferson Electric 480V-to-120/240V dry-type transformers.
