T5 light question

[aquamike]

Hi guys,

Would anyone be able to share with me:

Do 2 units of T5 1ft lights produce the same amount of light as 1 unit of T5 2ft light?

thanks!

1ft t5 tubes should be around 8w. While a 2ft high output tube is rated at 24w. Furthermore, 1ft tubes are not common and you will not find much color choices compared to the reef specific offerings from ati, geismann or even the more economical brands.

Ok. From what I understand, the W or watts refer to the energy consumption of the bulb correct? So what I am curious about is whether 2 x 1ft bulbs produce the same amount of light as 1 x 2ft bulbs.

Because if the answer is yes, then (from an energy efficiency point of view) that would mean that 2x 1ft bulbs are a lot more economical to run.

energy efficient but not cost saving

don't forget you need to change tube once a year
