1000w halides

[EnglishReefer]

Hi all,

Anybody using 1000w halides at all? any info would be nice.

What sort of coverage can you get with a bulb of this wattage?
What sort of ampage do the ballasts run at (esp on startup)?
Are they mounted horizontally like 400w bulbs?
Do you need any glass shielding at all?

Thinking of a single 10k bulb (aqualine/blv) over my new 4x2x2.

Cheers

As far as I know, there is only one member of the board who is using a 1000w metal halide lamp. He has a 54-gal corner tank with SPS, and over it he has mounted a 1000w 12,000K metal halide lamp in a horizontal reflector perpendicular to the front of the tank. He also has 3x400w 20,000K lamps mounted horizontally over the same tank. It is definitely an extremely lit tank.

The coverage you could expect from a 1000w 10,000K mogul base metal halide lamp like the AB-10000 or the Ushio/BLV, would be approximately 4'x4' provided the lamp is mounted 2' above the surface. Even though this lamp has a quartz glass outer sleeve (unlike the double ended types), you would still be safer to employ a fixture with a UV shield.

IMO this would be more than adequate for a tank 4'x4'x2' but you could certainly add to it if you wanted more intensity at the outside edges of the tank or if you wanted actinic supplementation or dawn/dusk effects. In any event, the central 3'x3' area of the tank would be very well lit indeed.
