@Stephenj37826 came up with this cool idea of a Plug n Play HID Duct cooled retrofit Kit using the LED's
Lets see what it looks like.
Math first...
4 x boards on 2x HLG240H-2100
1/8 inch Aluminum plate. Air cooled.
Total Wattage 540 Watts
About 490 watts into 1216 Samsung 561 C diodes
Case A with driver Loss, Case B without driver losses
Case A
80460 lumens.
164.1Lm/w
Estimates:
LER 321.60 lm/W
QER 4.86 µmol/J
50% at board level. 2.47ppf/w
Case B
80460 lumens.
149.4 Lm/w
Estimates:
LER 321.60 lm/W
QER 4.86 µmol/J
46.5% at system level. 2.26 ppf/w
PPF ~ 1250 umol/sec
i think similar to single end 1000W in output
There will be losses due to the glass.
It has 4 legs and can be placed inside the hood.
Uses its own HLG power supplies and old ballast is not needed and some rewiring is needed to power the new drivers.
You can build these on your own.
Or buy them pre assembled. Pre assembled will comes in 2 sizes. Best to share your fixture name so that @Stephenj37826 can recommend the kit size that will fit.
Estimated $649 for pre assembled until End of Jan.
Estimated $699 for pre assembled until End of Jan for a similar design but completely passive and for use without duct cooling. More details for this in 2 weeks.
Sphere data. Not available. Found a new test lab for Sphere testing. got the quotes. Saving up $$$ to get boards tested by end of Jan.
Enough of the numbers lets look at some pics in action at local store.
