It's working now for me too. Dunno why it took its sweet time.. Schtoopid computer.
Yeah I seem to remember back from my more active days of growing orchids that hydroponics shops didn't like to carry anything 250. It's sort of like how aquarists don't seem to like 175w because 250w is just a little bit more light for close to the same wattage and there's more choice. But in the plant world 400w is our 250w and nobody likes the 250w because 400w is more light and more choices and blah blah blah. Plant people want to light up an entire room or greenhouse with HID where us water geeks like to keep the light contained to a small area but bright as all heck IN that small area.
Having said all that I think there is a Venture 250W that is 5500K. I think they are the big globe style lamp though so that probably doesn't help you at all.
