Whats The Diff.

[fishdawg]

whats the diff between a t5 plant bulb and a t8 plant bulb? which is better?

the t5 is more intense, so penetrates more. you get mor wattage per inch of light.

the t5 is much better.

The T number of a light bulb relates to the size of the tube. T8s are 8 8th of a inch in diameter, T5s are 5 8th of an inch wide. In the old school days you used to be able to get T12s which were 12 8th of an inch wide. As Ian says, T5s produce a more intense light and produce more light for a given length (i.e a 22" T5 tube is 24w, whereas you need a 30" T8 tube to get 25w). Im told the light penetrates into the tank better with T5s, so good for deep tanks.

T5s are more expensive though.

Have a quick read of this thread:

some people found this fairly interesting; its got pictures which should aid you in recognising whats going on. Lights can be quite confusing...

There are 2 types of T5, high output and power compact... T5 just means that a single tube (not a bulb, just a tube) is 5/8's of an inch. Have a look at that thread
