How much output do you want?
If you want really high output on a budget and can go bit above 5000K, a member has 5700K, 100W COB’s for sale here:
$16.50 shipped price for ~10,000 lumens that Maukka has verified at roughly 95 CRI and high R9. You will need at least a 30V power supply. Optic choices will be limited, but it can be used as a pure flood source, or with barn doors.
100W might be a bit beyond the reasonable heat shedding capacity of the standard Intel stock cooler.
It will have a slight green tint, similar to typical LH351D or Nichia 219C emitters. White balance should be able to take care of that in most situations.
If you want something that can be used with a readily available optic such as a Carclo triple or quad, the LH351D is probably the best price option.
