Hydroponic lights

Has anyone ever looked in to using hydroponic lighting for their tanks? There is a shop near me that sells hi power T5s and powerful LED lights at a fraction of the price that are used to grow plants (probably cannabis too!)

Yeah it's not good. They use a different color spectrum for the horticulture industry. A lot of red and yellow, which will just grow algae..

You could replace the T5 bulbs.

If you are looking to inceease your light level I would be worried about the reflectors being sub par on a hydroponic unit. Ideally they should be a mirror finish.

Isn't white suppose to reflect better? If so a spray can paint job would suit you well.

White kind of reflects. But not very much, shine a flash light into a mirror and then a white wall and see how much reflection you get. Basic reflectors will be the cheap crappy plain white plastic or painted metal. Better reflectors will be a non polished piece of metal. The best reflectors are either well polished pieces of metal or mirrors. Between the 3 standard types of reflectors they will all have different light intensities underneath the bulb. That's the prime difference between different flourescent light fixtures of the same power.

Hydroponic lights

The hydroponic led light I picked up for a FW planted tank is lots of reds and only very few blues.
