F32, T8, T12, F40, etc
These numbers are based on ISO standards and are fairly straight forward. A regular lamp size will look like this: F32T8. It can be divided into two sections, the F number and the T number. These are used to guarantee compatibility between lamps.

F stands for "Fluorescent lamp". The number afterwards stand for the wattage. In some larger or older style lamps, it instead stands for the nominal length of the lamp.

T stands for thickness, more or less. This is calculated in 1/8" increments. This means a T8 lamp is 8/8ths of an inch in diameter, or 1 inch. A T12 is 12/8ths of an inch, or 1.5" in diameter. A T5 is 5/8" in diameter.

All F32 and F40 lamps are essentially 4 foot long lamps (47" if you don't count the pins). The FR71T12 is actually a 71" long x 1.5" diameter lamp that can handle from 80-120w and is typically run at 100w. It uses the different use of the F number.

If you see an R next to the F (ie: FR32T8) that means the lamp has a reflector built inside of it. This is not really ISO standard nomenclature, but it is handy to differentiate between reflector and non-reflector lamps.

The most common sizes we talk about are:

F32T8 - 4 foot long, 1 inch in diameter.
F40T12 - 4 foot long, 1.5" in diameter.
F71T12 - 6 foot long, 1.5" in diameter.
F54T5 - 46" long, 5/8" in diameter.

Solacure Means Quality

Solacure ultraviolet lamps aren't just good, we guarantee they are the best. We don't use stock parts anywhere in our products. Our glass is a special blend, and more transparent to UVA and UVB. Our 32 watt lamps use 60 watt rated cathodes and are tested at almost 70 watts of power. Almost all our lamps have built in reflectors. All are designed to be overdriven to extra high wattages. We test, and test, and test our lamps.

We stand behind everything we sell and guarantee each will perform exactly to specification, or we will replace them. We don't want your business this week, we want it every week, and we are willing to earn it. There really is a difference in quality when it comes to ultraviolet bulbs, and Solacure tops the list.

Buy with confidence: We like what we do, and we've been doing it for over 30 years.
