LED's Question -To Intense?

[Y-Diver]

I bought a LED tube strip for my 29 BioCube as supplemental light. After installing last night, I am realizing that the lights seem to be very intense! I wanted to ask the LED/Lighting guru's if the lights are going to burn any of my coral? The tank Specs are as follows:

Original Hood W/ 150W 14K Phoenix MH & 2 36W PC's
All lights are in the hood including the new LED strip.

The Aquarium houses a large variety of SPS, LPS, with a few Zoa's

The light specs are as follows:
* Size: 3/4 inch tube x 12.25 inches long
* 12 inches of power wire from LED Light Tube for easy connection
* Reverse polarity protected
* 44 Ultra Bright 5mm LEDs
* Narrow viewing angle
* End Caps are sealed to help prevent water, duct, and insects from entering light
* Crack resistant rigid polycarbonate tube
* Small and compact

Probably not an issue. I replaced a 150W MH + 36W T5 actinics with a 90W LED fixture (90 x 1W semiLEDs) and although I noticed some slight bleaching by pieces VERY high up everything has adjusted fine. You aren't really adding enough light to cause an issue IMO.

Hope that helps!

You will be fine... If you happen notice any bleaching just cut the photo period down for a week and ramp it back up slowly over the course of 2 weeks or so...

Sounds good Troy. Should I have the photoperiod be the same as the PC's?

Thanks.

Like the others have said, you are most likely fine. Those LEDs aren't particularly powerful, even in mass numbers, so PAR levels shouldn't be to the point where it creates problems. The tight viewing angle is probably why you are seeing it as bright, as the light is very focused. Keep watching the tank though for any reaction.
