TCP 31975 - 32058-65K 58W T6 CIRCLINE 2C Circular T6 Fluorescent Tube Light Bulb

This bulb may be 3700 lumen but it only has a 2700k color temperature. That is off by 3800k listed for the product which is 6700k by the way. The page and bulb listed in my purchase are not the same as the one received. Buyer beware, everything from TCP from ballasts, clips that hold the bulb in place, to the actual lights themselves are cheaply made and have inaccurate product dimensions. If you can, avoid the brand, I have tried numerous incandescent bulbs from TCP because they are they only ones that will fit the light fixture only to have them die out after a couple of months or produce a horrific light to read by. Oh and this thing gets liquid hot so it can replace a room heater if need be.
