Hi Everyone,
Please excuse this confusingly-titled question.
One of my sons has to do a science assignment over the next few weeks. It's not a full-fledged science project but it's still an interesting project. He is going to compare the growth of a few different plants in 2 nano Fluval Spec tanks, one using the 31 LED Spec light (or 2 of them), and the other using a fluorescent light with similar lumen value (and kelvin value, if we can find it). He wants to find out how the plants (mostly green, one red) respond to LED versus fluorescent light.
I can't figure out how many lumens the Fluval Spec's light is, and it turns out that different light emitting diodes have different brightnesses, so just counting the number of LEDs won't help.
Does anybody know how many lumens are in a 31 LED Spec light? (I asked at the store and they didn't know, and I couldn't find this info on the Fluval website) Can anybody suggest a fluorescent bulb that might be similar? (eg. 7 watt...)
I know that there are many other variables that he won't be able to control for -- the kelvins won't be the same, for example. But it doesn't have to meet science fair criteria, only offer him some chance for observation and fair comparison.
In addition to finding a bulb for the second Spec, he would appreciate a link to some information about how different kinds of light affects plants (different kelvins or spectrum or types of diodes, probably, not low light versus high light).
After he finishes this project, he will donate one of the tanks to the school, so it will have a happy outcome no matter what.
