I months ago I asked for help to build a COB grow light' so this is the step but step summery/instructional from that thread. To many people to mention that have helped but thanks bros.
Step by step style instructional of a build, including what Color wire to another and preferance of mounting the COB etc.
Cree CXB 3070 LED COB ... 30. - 55.00
Alpine Artic 11 fan heatsink combo
. . .16.00 dollars
Meanwell LPC 60-1400 driver . . 16.00
Small tube of thermo paste ..
soldering gun . . .
Soldier . .
Flux . . .
Kapton tape . . .
22 AWG wire (stranded or soild)
When you receive the Alpine Artic 11 heatsink and fan combo, be careful to not to touch the pre-applyed thermo paste on the underside of the heatsink,
you prolly will want to use it, for ease of build.
You may prefer to remove it and apply your own, read further to decide...
1. Attaching the COB to heatsink
using thermo paste. Remove the factory paste with rubbing alcohol, note: the alcohol will dull the finish so it that bothers you be careful to stay within the cob space perimeters.
If your using the Artic 11 pre-applyed thermo-paste skip to step 5.)
2. With masking tape mark out the area outside where the cob will set. to keep the paste from getting all over.
4. Install the COB to the heatsink.
Once you have the paste thinly applied.
(there is an holder by Ideal made for the CXB3070 but my opinion after installing one, you really need to have the two holes drilled precise.
5. it's much easier to use Kapton tape after you thinly apply the thermo-paste you just set on the COB and place a small weight on top the COB (careful not to scratch or dent or crack the COB) let it set up over night?
Due to the Holidays, wiring the fan and wiring the driver will be coming up
