I made my own light fixture for T8 LED tubes and I am seeking any input as to spacing of the tubes. I used 4 strip light fixtures and wired them for dual end powered lights. At this time the light fixture is 19" wide and I am contemplating adding more space between the lights to get a wider coverage area. Any thoughts on this? The side light has 5 bulbs in it because that is how many I could fit in there.

The 5 full spectrum that didn't seem to be putting out enough light were about $100, discontinued now. The double fixtures were free, the 4 light that I turned into a 5 light was $8 at a Facebook yardsale site. Included a pic of the plants to show how they are doing.

Doing a quick search on those fixtures, I would try to provide 30 w/ sq ft(actual power used) of the area you're trying to light. Also, if there are diffusers I would try and remove them. You will get better penetration. Most of the strip fixtures I've built work best with a solid sheet of diodes over the plant so put as many as you can fit.
