My Buying Guides on Testing Bb-40blk Bulb
What I Look For First
When I test a Bb-40blk bulb, the first thing I check is whether it matches the fixture and voltage requirements. I always make sure the bulb base fits properly and that the wattage is compatible with the device I’m using. If the bulb doesn’t match these basics, nothing else really matters.
