LED flood lights for fiberglass tank?

  • We are currently upgrading MFK. thanks! -neo
I use regular garden type LED floodlights on my 2 meter tank. I run a single 70w over the middle of the tank during the day and two 50w ones at night. That's plenty for me to grow plants and light up the tank nicely.

I'm not sure about using the car type LED lights - one of the big concerns I have would be heat. The garden style flood lights I use have big built-in heatsinks because they're designed to run for hours on end. The car type you're looking at doesn't seem to have much in the way of heat dispersal and is likely intended for using only for short periods of time. If you leave it on for hours there's a good chance it'll overheat and burnout the LEDs.
