just wanted to bump this since i never got a reply
Just finished Building my 150w Philips mastercolor 942 cmh rig. Made an aircooled version of the octagonal reflector in pontiacs DIY links thread.
edit: just took some pics and got some weird striping. Is my cmh operating funny? or maybe its standing waves?
the space is 22" x 19", temps are holding a steady 85F 3" below the hood @ the wall after 3 hrs of operation.

Sorry man, I can't speak for Simba and I have never used a Grozzila. But, my best guess is that, essentially, you would have an 800w lamp that penetrates like a 400w.
I agree...the penetration of the horz bulbs would not change, only the foot print they cover. That isn't to say that your yield wouldn't be as much as the 1000 might produce if your grow was laid out accordingly.
The 1000 penetrates more vertically and the two 400's will give you more horizontal coverage.
In my mind,I can do more with the larger horizontal footprint.

I wouldnt really recomend 2 400s at full power to try to match what a 600 or 1k did. rather id space them over the area to work take from the inv sqr laqw..
another option would be 1, 400 anda 250 in same hood.
again i would rather space them hout however if you had reflector or space issues its option.
Sorry been busy busy.. and i dont want any one ever to say i kept the thread alive so going MIA every so often
i completely agree.. (forgot SN now but there was a few colas growing into reflectors on this thread)
Oh the specialux. ya they cool for a minute.. kinda work..

Not advertising or pushing who i like..

has anyone successfully used a Sun System Harvest Pro switchable ballast with a cmh?

try a slower shutter speed (like 1/30th) or use a bounce flash and see if it goes away.
Try a camera instead of a cell phone and it goes away.

I just completed a dual foci vented parabolic hood that will be running 1K HPS and .4K CMH last night and am beginning the second today I am taking pics and will post the room build, from ventilated ballast shelf , remote ignitors and dual bulb ventilated parabolics. System is designed on a budget and is capable of running CMH and HPS separate or together. 2.8K over 48ft2 for 58.3W/Ft2 . ventilating an old school parabolic makes it run cool enough to touch the ceramic mogul fixture w/o burn and really keeps things cooler than A/C. I am excited by the expected performance of 1k of penetration and .4K of spectral goodness for my next round.

Yes, if the ballast is magnetic and has the number S51 in the ANSI code.

A complete from the ground up build of ballast shelf for a 2.8 K HPS and CMH system hand made dual foci parabolic hoods with ventilation and remote ignitor wiring.System covers 6x8 on light rails moving 4' and can be run as just HPS or just CMH or both I am adding a second timer and plug to the system to stagger my light hrs but am well pleased with the quality of ight from the combination

Considering that they test fire your bulb they would be the best, IMO.
Thanks for the advice,hoosierdaddy,just ordered one!
