I want to use an led bulb (100 lumens per watt) and around 5500-6500k. I have a severely underlighted 7 gallon tank.
15-23 watts in what lighting? CFL or LED. wattage is pretty inaccurate for LED lighting as some LED lights can produce more than 100 lumens per watt while others can produce about 85 lumens per watt.go for 15-23watts
I assume you mean CFL, what would your equivalent in LED will be?go for 15-23watts
Yeah, generally people recommend 2-5 watt per gallon but in CFL. Infact most light wattage measurements on the internet are in CFL. 15 watt to 23 watt led would be way too bright for such a small tank, I guess that wattage in CFL might fit.I meant led but Who knows. It depends on the bulb. You have to experiment.
I use PAR, photosynthetic active radiation values From a light.
