Metal Halide ballast info

Damn, that hood looks exactly like mine . I was going to order some of those bulbs as well. J&L said they were trying to get some in, but had no time frame.

Can a person buy a retrofit reflector for this unit , or do they have to make one ?

i dunno, i have that hood and need to make some reflectors for it as well. i think i might get some hammertone and try that.

j&l must be changing their minds, i asked them about bringing in iwaskai 14k 175's and they told me to try de xm 250 watt 20k's

electronic ballasts aren't known for high performance, but for economy. Also, XM designs their bulbs to run best on probe start ballasts -- hence the better numbers on the standard magnetic ballasts. It proves that XM did a good job fine tuning the bulb for probe start ballasts.

they test the Iwasaki 14K. I don't know ballasts but is the last one a probe start?

Yes, M57 is probe start.

I know I've typed in the list (of ANSI #'s and their meanings) a few times in the past. Let me do a search .... OK here is one, there is a breakdown of the ANSI numbers in this thread (second post)

nice.. the 175w has more output than the xm15k 250w

Bumpity...

Is anyone running the 14k Iwasaki's now on a probe start ballast ? What do they look like ?

The Iwasaki 14K has been making quite a buzz on RC. I haven't seen pics (which are almost always misleading in terms of what you'd see in person) but from all accounts I've read, it's a true 14K colour bulb (white with a very slight blue tint) with enough PAR to give many 250W bulbs a good run.

You guys missed this thread. I've been running this lamp since June.

I run XM 10k's 250W on another tank, and the intensity is virtually indistinguishable. Not that XM's are no good, quite the opposite in fact, they're a great lamp and I'm a big fan of them. But as good as they are, the Iwasaki is just hands-down the best 175W lamp I've ever run. I regret selling my other 2 M57 ballasts now. I can't wait to see this lamp in other wattages.
