1 Watt???

[Jhigga15]

Hello everyone,
I built a Biocube 29 HQI. It has the 150w 14K light(7 Hours a had). After about 2 months I wanted more "pop" out of my coral. I put 2 Current Powerbright strips with it (8 Total Watts that I rand 10 Hours a day) I quickly gave my coral light shock along with bleached my nice purple rocks...

I guess my question is... How much is 1W and could and extra 8 watts really thrown everything off that bad???

Thanks
John

Watts are not watts when talking about lighting. Well consumption wise yes but light output per watt no. Some LED's can be very intense. From what I have read these Power Brites are very intense directly under them.

LED par is very high, even with small 1watt fixtures. They could have shocked the tank inhabitants.

A watt is an electrical measurement, not a light intensity measurement. There is a correlation between more wattage and brighter lighting among like lighting, but it doesn't translate across all types. That's where you run into energy savings when running florescent lighting vs incandescent or LED vs MH. 8w of LED goes a long way where as 8w of MH isn't squat.

If you want to understand what a watt is and how it falls into the complete realm of electricity go to www.bcae1.net and read up on it. If that link doesn't work just copy it into google. It's either correct or close enough for google to figure it out.

that link did not work, only car audio stuff came up, but thanks anyways...

Those lights really messed up my set up... wayyyy to much:sad2:

Thats why I tell people to be careful when switching over to LEDs... Bummer dude.

Any one else have any more info on this???

Exactly.

You're forgetting about efficiency. LEDs are far more efficient in transmitting that electrical power into visible light. So you cannot say "only 8 more watts of light bleached my corals."

Odds are it was simply too much light given without acclimation. Caulk it up to a learning experience and move on.
