LOL no way man. My local hydroponics shop has the 250w Lumatek dimmable for $99 or so, lamp cord and socket is another $15 plus another $15 for the sylvania bulb. I have no use for a reflector as I'll be running a vertical setup in a small tent.Ew - a complete 400w digital dimmable aircooled setup costs $170 (hood, ballast, hangers, cords). I really really hope he didn't spend $550 for a 250w.
For a 600w or 1kW I would be in favor of the more expensive bulb. But there is a difference, a generic 250w bulb is $10, a hortilux is $124 - a 1000w generic is $80 and a hortilux is $130. For the 250w that's an increase of over 1000% in price, for the 1kW it's less than an increase of 100%...
