Um .. Ok now I'm confused. Doesn't that fixture already use DE (double-ended) lamps? Or are you asking if you can use a SE (single-ended) lamp in there?

The only bulb type you can run in that fixture is a 150w DE. You can pick your brand of DE bulb and the color temperature.

 Ok Like Delphinus and other have said, the term HQI is abused and not used properly at all in our industry. The HQI ballast is built to replicate German reactor type ballast outputs and comes in several different wattages, 50W , 70W, 150W, and 250W. (If they are making a 400W now I have never seen it) but I believe they use the Son Agro ballast for the 400 watt HQI (DE) but I am not sure. now a 250W HQI ballast will drive any 250W bulb on the market but a DE bulb has to be driven by a HQI ballast. make sense? so there is a difference in the bulbs a DE needs a DE holder, they are smaller profile and will put out close to the same light as most 400W set ups, but a 250 watt (quality bulb) SE run on a HQI ballast will put out more light than than most 400W systems and with reflectors thrown in the results can be amazing. the DE bulb is great for tight spots, smaller tanks (less of a foot print to run say 2" x 2" at a max) where the SE will light a 3ft x 3ft spot with about the same amount of light intensity. Also there are a lot more choices in lights on the SE side but DE is getting better. Steve

So a 250HQI would put out more light that a 400W SE of equivilent spectrum?
So if I upgrade my 150HQI aqualight to a 250HQI aqualight, is it like running 400W SE light system but only drawing 250watts of power? I always thought it was just a typical "sales pitch" when they say a 150HQI performes to a standard 250W MH.

I can't believe a 250 DE would put out the par of a 400w SE, I am going to look for some studies.
