Screw It Into the Existing Socket. Get 6,500 Lumens. Done.

A 50W LED low bay with E26/E39 base that retrofits directly into existing sockets — no rewiring, no new junction boxes, no electrician for half a day. 130 lm/W, 6500 lumens, metal housing for real heat dissipation, and a low-UGR luminous surface that doesn't blind workers below.

E26/E39 Base — Retrofit Without Rewiring

Screws directly into existing HID, CFL, or incandescent sockets. For facilities with dozens of low-bay fixtures, this means a fixture-by-fixture upgrade with zero electrical work — maintenance staff can do it with a ladder.

6,500 Lumens from 50W — Replaces 175W Metal Halide

Same light output as a 175W metal halide at 70% less power consumption. No warm-up time, no re-strike delay after power interruptions, and consistent color temperature from day one to day 50,000.

Low UGR with Large Luminous Surface

Unlike corn cob LEDs that create harsh point-source glare, this fixture spreads light across a large diffused surface. Workers underneath get even, comfortable illumination without the squinting and headaches.

Metal Housing with Proper Heat Dissipation

Durable metal construction manages thermal load the way corn cob bulbs in enclosed fixtures cannot. Better thermal management means longer LED life and consistent lumen output over the fixture's 50,000-hour rated life.

120–277V Universal Voltage

Works on any standard North American circuit voltage. Whether the facility runs 120V, 208V, 240V, or 277V, the fixture adapts — no ballast to match, no transformer to source.
