  • can these be used outdoors, under an eave?

    A. As long as the fixture you will be using with these are rated for outdoor use and this is the type of bulb it needs, then yes you can use it outdoors.

  • Does this bulb emit some light from the base? I need to replace a bulb that came with my track lighting fixture that allows some light at the base to illuminate the blue globe.

    A. This should allow some light to escape through the back, but I would recommend contacting the manufacturer of the track light and see if they have a specific bulb they recommend. Thank you.

  • I bought a home with FEIT MR16/GU10/50w/120v bulbs in the kitchen ceiling, but the room is not bright enough. FEIT says the lumens are 1500, so I am searching for this spec'd bulb eith the greatest lumens available. Can you help?

    A. FEIT MR16/GU10/50w/120v bulb will only be 1500 lumens. Lumens can range from 1500-3000. I would look for a bulb with more lumens
