E40 LED Retrofit Lamps from China
1 resources tagged with "Retrofit Lamp"
E40 LED retrofit lamps (typically 30W–80W in T46/T65 form factors) replace legacy HID bulbs in industrial high-bay and street-light housings without rewiring the fixture. The numbers that matter when sourcing from China are efficacy (180+ lm/W on the better drivers), driver quality, and thermal management — the LED chips age fast if the heatsink and driver run hot inside a sealed housing.
When you source retrofit lamps, confirm whether they're designed to bypass or work with the existing ballast, because a lamp wired into a live HID ballast can fail early. The common pitfall is buying on lumen and wattage claims alone; ask for an LM-80/TM-21 lumen-maintenance basis and verify the driver, since cheap drivers are the usual point of failure, not the LEDs.

FAQ
Do E40 retrofit lamps work with the existing HID ballast?
It depends on the design. Some are ballast-compatible, but most reliable retrofits require bypassing the ballast and wiring directly to mains. Confirm the wiring requirement before ordering, because the wrong type fails quickly.
What certifications do LED retrofit lamps need for export?
For the EU, CE (LVD and EMC) plus RoHS; for the US, UL or ETL safety listing and FCC. Energy and lumen claims should be backed by LM-79/LM-80 test data.
What MOQ and lead time are typical for OEM retrofit lamps?
Standard models can ship in modest quantities; OEM driver tuning or custom optics usually pushes MOQ to a few hundred units with 30–40 day lead times.
