Customer Questions & Answers

I have a Sylvania Cool White F13T5/CW light bulb. I measured it 20 1/2 inches. But this T5 13W 4100K is 21 inches. Are they different?

Asked by: John
This bulb will work. The measurement including the prongs is 20 1/2" and just 20" without. Not sure why they say 21".

Is there an LED replacement for this light?

Asked by: Jd
They are available, I have seen them online, not Philips brand. The LED bulb is more than triple the price but has a much longer service life.

How does one remove the bulb safety?

Asked by: Joe
You just grab the bulb in the center and gently rotate it about a quarter turn until the prongs of the bulb line up with the slots in the fixture such that it can slide out. It may give resistance when you first start to turn which then you can try turning it the opposite direction, but you do have to turn it to get it out.
