Read these five fields before ordering
Use the old bulb and fixture label together. A shared base or wattage figure answers only part of the fit question.
- 01
Socket and shape
Match E39 exactly. The T38 code describes the bulb envelope, not the socket. Open the E39 base guide. Compare bulb shapes.
- 02
Electrical rating
The source lists 120/277 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 15,000 lumens. The 100 W figure is input power, not brightness.
- 04
Physical clearance
The official maximum overall length is 11.1 inches. Check shade, cover, and neck clearance.
- 05
Heat, controls, and location
The source approves totally enclosed fixtures; dimming is not stated; the location rating is Damp.
