New Customer Quite Satisfied


I use these bulbs in desk lamps for reading and have another we use to illuminate the mixer board for my rock band VIEJOS at darker forums. Works great, lasts quite awhile, and the full spectrum makes reading easier for me, less eye fatigue. Shipping was excellent and quick.

Q & A
I m in search of this type of bulb, but what I need is a Daylight, 6500K, 65W, 4 pin. Not easily found, but hoping you can give me a clue. The last time I purchased from a lighting store, but they've gone out of business. They had to special order it but I don't know where from. Is there any way you can help?

Has anyone used this as a replacement bulb in the day-light desk or floor lamps sold by Big Lots?
