HQI question

[inspire0522]

i have a Commercial Electronic HQI light 500w... its used for lighting up a work area... i was just wondering what is the difference with this type of light and one meant for a tank... other then the bulb.. thanks for any help

The spectrum of light that is emitted from that bulb (and any other bulb for non-aquarium use) is far too low and yellow in color. Using that bulb could induce algae growth.

You would be better off getting a bulb made for aquarium use.

You can use the HQI, but I would get a 10-14k bulb meant for reef use.

other then the bulb

Doh!! I guess I should have read it a little closer. The fixture is fine as DragonForce said as long as you have the correct bulb for aquarium use in it.

I have to say I have never seen a 500 watt HQI bulb that is in the right spectrum for aquarium use. If you find one, it should be fine.

Are you sure what you have is not a 500W halogen shop light with a double ended bulb. They are common in 500w.
