Bought a 575 ballast, two bulbs, and everything else that goes with the kit. Was a good deal and a smooth transaction.
two notes tho...
One thing that calmed my nerves a little was that every time i searched for the elmo 575 watt bulb replacement (ballast was ripped from a solar deluxe), google showed me a single ended 575w. Upon further inspection of lamp mount, it looks like he already made a few mods for it to accommodate the typical DE hmi 575.
The only complaint that i have is that one of the cables leading to lamp had some real damage on it. The end where there is the eyelet thing that you screw onto the bulb is almost ready to fall of the wire. Only 3-4 of the copper strands are still attached to the eyelet, while the other 10 strands just popped of the solder joint. An easy fix, but im glad i spotted it before the thin copper wire started to smoke
