I was posting in another thread. It might be possible to do a 300W HID with an appropriate bulb in a 11.5” reflector (head is 13 inches) and attain 5-6M cp.
You will be overclocking the bulb heaps though, the good thing is that bulbs are cheap.
Note : It’s not going to be a practical use light, just for fun kinda project.
However it’s going to be very difficult to purchase for you guys in the states, europe, austrialia etc. Shipping is not going to be cheap, but definitely would be way below $500. You might wanna search ebay to see if such China sellers sell there?
300W with 18cm reflector. USD 26. That’s to scavenge the bulb and ballast. I am not sure what are they using for the 300W bulb option and the most important aspect of it all that determines the throw ie the arc gap length, but i suspect it’s those H7 base car lights stuff.

Alternatively you can get 220W variable power output ballasts (12-18V input) and gun it into a 100W H7 HID 4300k bulb which has an arc gap of 4-5mm, limit your run time to within 1 minute. (well, turbo mode LED lights are all the rage nowadays, right?). Replacement bulbs are cheap, like usd 3.50 for 1 pair of 4300k. :money_mouth_face:
13” reflector host, i need to search for it again, it’s basically a Sunca host (HK/China based)
If i remember correctly that is usd 30 or so on Taobao.
6 million lux should be doable. The hotspot might look pretty yucky though.
My 13” Sunca head host, you’d have to do some DIY work and run some wires out to a PSU, some SLAs or some 4-6S RC Lipo packs.
My version, was able to get 3.8M cp with careful focussing, with a 55W bulb with 3-4mm gap and 100W ballast but probably running on about 80W output (maybe even lower) due to huge battery sag on its 12V 5.5AH SLA. It would give higher output watts when running at the upper end of its 12-24V working range when I connect it to an external PSU. : 13-inches Humongous reflector HID host found (final reading of about 3.8M cd)
Some other guy’s version. He got 2.6M cp on his host and 100W ballast, not sure which bulb was used. :

Not very practical in reality, but it would be fun for meetups and still doable on a reachable budget + not needing extreme technical skills.
