I started out with really old used 400W MH in bell reflectors, the kind of lights seen in gyms and such.
I upgraded to HPS on magnetic ballasts, then later got digitals for them.
Then I discovered 860W CDM lights (big brother to 315W CMH) and ran them on those same magnetic ballasts.
About a year ago, I took delivery of a bunch of water cooled COB LED modules of my own design and I've been running these ever since.
In the last few weeks I just got a bunch of 250W Razor bars from HLG, with which I'll retire my remaining HID lights.
Finally, I have a pair of very early prototype quantum fixtures with 4 boards each, running 'wall washer' lenses that throw light from overhead onto an adjacent vertical surface. After a design iteration, I'll be getting more of these.
