I think if you wanted lots of light and didn't have much money you would buy low-noise CPU coolers and strap 100W LED arrays to them. You could rack them up side by side and achieve quite a lot.

 

You can get 100W LED arrays that claim high CRI for $50. Yuji sell perhaps more reliable ones for $100. A reasonable low-noise CPU cooler can be had for under $50. Depending on whether you trust eBay auctions and how good a cooler you want to risk, if you don't want a point source you can therefore build a big LED array, perhaps to drive diffusion, for around $1.50 a watt for the core power components. Making it into a usable tool might take some engineering, but if you're happy with a covered wagon that's not rocket science.

Thought multiple views could be shared here.

 

What is the best way to blast an area with light beyond a couple 1k moles which are incredible for their price , but can still stay under let's say $1000?

Maxi Brutes? A cheap HMI I'm not aware of? Just more Moles?

 

Thanks for any findings you can share from your career.

 

 

3-4 of these: Lithonia Metal Halide lights - $327, 1500w each.

Possibly, although many bulbs to fit that have a CRI of about 60 (that is, practically unusable except for special effects) and they will be magnetic ballast and flickery.

 

Better bulbs are possibly available but would cost half as much again.

Phil is correct, manufacturer's website states transformer ballast.

....and no barn doors, lenses or any type of rudimentary focusing mechanism.  These are more aptly called MBLs, Make Believe Lights.

I dunno, if there are decent mogul-based 1.5K metal halide bulbs out there, it'd only be as bad as a mag ballast HMI. The design is essentially a scoop light, but I could see firing it through an 8x8 and having that be an entirely reasonable thing to do.

 

If you just want a moonlit backlight for a night ext, it's not completely silly.

 

As you may realise I'm quite permissive about this sort of thing!

 

Edit: I can't find a better bulb. Iwasaki did have one with 92 CRI (that is, about as good as HMI) but they may be discontinued.
