Question:

We care looking to replace our 921 bulbs in our camper. The existing ones are way too bright for our taste especially in the living area. Way too glare y for reading. Is there a bulb for this application?

I have two 921 light bulbs for you to choose from. You can go with either the Replacement Bulb for Optronics Aero-Style RV Ceiling Lights part # A921B or the Replacement Bulb for Bargman Interior and Bunk Lights part # 30-90-021.

The brightness of a light bulb is measured in one of two way, candlelight and lumens. 1 candlelight equals approximately 12.57 lumens. The lumen rating of each bulb is as follows:

part # A921B - 253 lumens or 20 candlelight
part # 30-90-021 - 263 lumens or 21 candlelight

Therefore, the 921 light bulb that produces the most manageable brightness is the part # A921B.
