Yep digikey is a bit cheaper And only a 5 week lead time, apparently.

U channel is always an option 1.5" x 1" does a great job up to 50W. 2" x 1." will do 75w.

I had a quote on these for £20 on 160 units.

anybody want to go halfers?

Just look at what's already on the driver.

SJOW 17AWG 2C 05RN-F × × & 2 1.0mm2

I need to re write that thread now its outdated.

2.48 umol/j at system level @ 100w, with lens, migro claims.

Nowhere near.

Ill post some maps of the cxm22 gen4 next week vs an actual 2.48 umol/j light.

Here is a chart using 4x 4ft heatsinks with 2x hinflux strips per heatsink. 118cm heatsink length) HLg-480H-48a driver at full power. (same PPf output as f series (within a few percent) but slightly lower voltage) Its in a 1..2m x 1,2m area with the heatsinks on a 90cm wide frame with the heatsinks ...

LPC-60-1750 are dues tuesday ill test them.

These work fine for a QB132.

Only a £10 driver.
