Both are meant to be hung at heights, and both are very old tech, and both are very overpriced.

What are you growing in?

I'm planning a solar passive greenhouse and need some additional light (only LED) that I can hang quite high. Efficiencies of over 3 umol/J seem quite up to date to me. Are you talking about the LEDs used? Please, I'm happy to hear any recommendations. Ideally 900 umol/m2/s reaching the canopy from a 1,8m/6' would be my dream. The CL GH PRO are rated at 900 umols but I believe that might be at 18" max.
I still have about 9-12 months before making the buy. I'm currently in the planning and budgeting stage. So maybe by then efficiencies will be up to 4 umol/J, where it will be much easier.

Maybe just wait a year then until your project is complete. CLW hasnt come out with any new tech in years, as for the other I’ve never heard of it myself.

I highly doubt either is pulling 3 umol/j
