I was thinking about buying this:
PT 121 C11 MPB Optoelectronics (Mr_Li)-in EL Products from Electronic Components & Supplies on Aliexpress.com | Alibaba Group
because I have blue PT-121 from DTR and purchased the original Luminus driver for it, but maybe you are right - I would better buy 2 of those 100W LEDs 12USD each and make a 200W spotlight.
I need it to illuminate my lab when working with visible light curing glues - they quickly cure at blue or sun light but may be insensitive to the pure green.
Why buy the Phlatlight, do you need such a small emitting surface area? This 50 watt green LED isn't very big and will put out plenty of light: 10W 30W 50W 100W Watt Multi Color High Power LED Chip Flood Light Lamp DIY New | eBay.
Although the above is far cheaper, I can fully understand needing as small an emitting surface area as possible when building a flashlight, a smaller emitter area allows a tighter beam and further throw, same as with laser diodes, single mode laser diodes with small emitters have far lower divergence than multimode diodes with their much larger output surface. Due to that, I believe the Phatlight LED probably has the most output for its small output aperture, just that the price is wayyy higher.
Power Input: DC:30-34V
Color Temperature: Green（Wavelength 520-525nm）
Color Rendering Index: 45-65Ra
Luminous Flux: 3500-4000lm

The 50W one is roughly 2.25 X 2 inches and less than five dollars delivered. I have a concern though, some China sellers show the outputs at different amounts, makes me wonder if some of the numbers are wrong or just inflated. Maybe some units put out less light than others, depending upon the manufacturer? Hmmmmm..... Years ago I was ordering some of these to build a UFO RGB landing area beacon (joke, my friend) and found that a couple sellers appeared to have given inflated output numbers to compete with others.
