One thing I thought I'd mention is that when my Procyon gets closer than 24" to the canopy, the leaves twist sideways and "ram's horns" show up - like they're responding to heat stress. Which is relieved as soon as I move the light up.

I guess the lower lux # is due to it emitting only blue & red light and that the lux measurement totals for the HIDs include the other spectra(?) Hence my plants reacting as if they're receiving too much light when actually the lux reading is lower than what it would be with an HID b/c plants use more red and blue. I'm just stabbing around here. What do you think?
I think you are a pretty good stabber.:thumbsup:
You have a handle on this.
Anyway we can help? Don' be shy.

Weezard Reviewed by Weezard on . Procyon Output Data Been a little busy lately so just starting to get round to the measuements I was curious about. This is my first round of data collection for the Procyon 100 luminaire system. I'm using a CEM DT-1308 light meter for all measurements. I've been trying for a week to get the mete's sensetivity curve but haven't found any info other than what was included in the user's manual(which was so small I couldn't get the numbers off of the scale). The manual also states that the meter is weighted to Rating: 5
