I feel like if i put 2 par 20 5000k led bulbs on my 29 gallon bowfront it would be enough. I also have 1 18" t8 bulb on it think itwpuld be good enough? They are rated 50 watts equevent. Let me know whats up!

Hello,

5000K will grow plants.

2 led bulbs of 20 watts must be sending a lot of light, difficult to say if you have low/med light though.

But I am quite convinced you can grow plants with that.

Its LED so its mesured in par but runs on 9.5 volts which is equal to a 50w other bulb. So in theory i would have 100 watts on the tank with the 2 lights. So 100/29= 3.44watts per gallon. So i hope this will work out!

Let's see if the theory matches with practice :)

LEDs give light in a spot unless you are using a lens to scatter the light. 5.000K doesn't mean much. Plants love full spectrum, unless your LED emits light in a wide spectrum the color temperature does not tell the whole story.

I don't use LEDs myself but AFAIK it is better to use more LEDs of lesser power scattered in your fixture than two lighthouse graded emitters.

It has a nice spread of light. They both overlap in the moddle of the tank. Would suplementing other colors and such help?
