Nice Grow Pics.
For me I have had the best growth with Cree and or Luxeon LEDs.
A few months ago our team had the pleasure to compete in a frag growing contest which we won.
About 1mm growth per day

Water quality was important, along with a new Cree LED Fixture, we used Reef Grow Supplements.
We all know that a 420-450nm only LED can grow coral especially less light demanding ones.
Spectrum matters and Bridgelux no longer produces the dated 3 watt Bridgelux LEDs...Who does??? Whats their Spectrum/Binning???
Looks also matters as no one likes a yellow looking coral reef
Whats Driving them??? Will the driver last? or will I have to have Plan B like a backup generator when the EBay Fixture Fails???
That said quality importers specify upgrades to their import fixtures which gives them a much needed value option.
Personally if I cannot verify the spectrum I dont want it over my corals.
Do you really thing these LEDs are authentic produced by Bridgelux?

How many times have you seen this same graph?
Is it a copy or actual? Who verified this spectrum and at what settings?
Just some food for thought
