It may be classic technology, but it still works just as well as it ever has. Cool white light is best used in a kitchen, bathroom, office or retail space where task lighting is needed. This bulb will provide more of a blue than yellow light and is a clean crisp light with the ability to set the mood you are trying to achieve whether it be merchandising a store or cutting vegetables. Equipped with the ALTO technology, you can feel good knowing this is a more environmentally safe option with less mercury than the traditional lamp.

Philips 15W 18in T8 Cool White Fluorescent Tube

Q & A
I'm looking for a replacement bulb for an old fixture. The old bulb has no markings, is 17.2" from end of cap to end of cap, is 1" in diameter, and I don't know how long it is from end of pins to end of pins (quite possibly 18"). Does the 15 Watt, 18 Inch T8 Cool White Fluorescent Bulb by Philips fit my fixture?

In the Dark

Lamp measurements are taken from pin to pin. It appears that the Philips 18" fluorescent uses 15 watts, so this looks like it would be your bulb. The 1" diameter tells us that this is a T8 lamp.

What is the diameter of this bulb ?

Bob
