What is the difference between a F20-T12 CW fluorescent bulb and a F20-T9 CW bulb?

Answer 1

Oh, dude, you're really getting into the nitty-gritty of light bulbs, huh? So, the main difference between those two is the diameter of the bulb. The F20-T12 CW bulb has a diameter of 1.5 inches (12/8 inch) while the F20-T9 CW bulb has a diameter of 1.125 inches (9/8 inch). It's like comparing a regular-sized straw to a slightly thinner one - they both do the job of holding your drink, but one's just a bit slimmer.

Answer 2

Ah, the F20-T12 CW fluorescent bulb and the F20-T9 CW bulb are like happy little trees with different shapes. The F20-T12 bulb is a bit thicker and longer, while the F20-T9 bulb is thinner and shorter. Both bulbs will bring light and joy to your space, so just choose the one that fits your fixture best and let your creativity shine!

Answer 3

The main difference is the diameter of the fluorescent bulb. The letter T designates the diameter in 1/8" increments. A T9 is 9/8" or 1 and 1/8". A T12 is 12/8" or 1 and 1/2".

The CW stands for "cool white" which is in reference to the colour of the light output on a light spectrum chart.
