Can I remove the optics and plate that holds them in and run the light open like that? The spread with the optics is to tight for me. What will doing that do to the intensity of the light as far as par goes?

Thanks

edit: This is over a standard 10g tank. 12" deep

Thanks for the info. I was wondering about the salt factor. I also wonder how far off the water I should have the bulb if run without optics?

Bump.

Anyone else see a problem with doing this?

If you remove the plate and the optics, there is a risk of the MCPCB with the LEDs coming loose from the heatsink.

The actual pressure from the secured plate and optics holds the MCPCB in place helping with thermal transfer of heat. Once the plate and the optics have been removed, the only thing holding the MCPCB in place is the thermal paste, which is different from an epoxy. If for some reason the MCPCB comes loose from the heatsink, you'll dramatically reduce the life of the LED's.

We do not recommend running them without the optics and plates.

I guess if it comes off and the led doesn't last I will toss it and try a different brand. Unless you have 80 degree optics available for purchase.

I am running 1. Removing the optics would give me ideal spread but I guess thats not an option. I guess I will just run this without until it fails or buy a retro kit like I should have in the first place.

By removing the plate and optics, the LED's would fail due to improper use especially if the MCPCB comes off of the heatsink. Please try running any 3-watt LED (on the market) at 70%-100% WITHOUT a properly mounted heatsink and let us know how long they last.
