TWIN ARC MH Bulb ??

They may be the double arc bulbs made by Reef Brite. they have been out for a couple years, and I have not seen them in action, but there has never been a lot of discussion about them, so I don't know if they were a hit or not.. If it is the same on and not a clone, then it may be a good price, or a closeout on ebay. Here is the RB unit from AS

Of course, for me (and I'm sure you as well), it would boil done to the rendition and PAR.

why not just get a second mogal socket and a relay? Its not that hard to wire in a second bulb into most reflectors, then just attach a relay to switch the power to the bulb.
Question is, why bother? You only need 4-5 hours a day of main high power lighting, so why waste the time with a second halide bulb in the mix. Just use actinics(or T5's) to get the color you want and enjoy, and set your daylight halides to come on at a time when your not home.
The color and PAR of my radiums is great. Yeah I will get more PAR from a 10k xm, but not enough to put up with the lack of color.
I just dont get it, why do it with a 14k and a 20k, why not a 6.5k and a 20k...i dunno whole thing seems kinda pointless to me.

I was curious.. I was searching 250w bulbs and that popped up.. I didn't (and don't) know anything about them good or bad..
I would think that as you increase the number of arcs within a bulb, you decrease the output from the arc. (so this would have two 125W arcs in a 250W bulb... right?!?)

They switch when you turn the light off and back on
Actually what they were meant to do is this:
10k triggers at 6AM for 6hrs to 12PM, so the photosynthese need of the coral is satisfied, then the 20k triggers at 5pm (after cooloff period) for only 4hrs (or until the owner goes to sleep) for the viewing pleasure in 20k...

So what's the point of having twin 14k like this one
