diy led problem / help
Hello everyone! I'm making an LED light for a 2x4 area of mounted orchids, consisting of 3w LED's: 4 cool white, 4 neutral white, 10 warm white, 4 deep red (660nm), 1 royal blue and 1 actinic 420nm. They are on a 10x14" heat sink.
I'm having a huge problem. I used the Arctic Silver thermal paste and it's been almost two weeks, and the LED's are still not adhering to my heat sink. Was I wrong to assume this stuff would act as adhesive? I've attached a picture of the whole setup, and I'm eager to get soldering.. my questions are,
Can I just lift the LED's up a little and dab some super glue in there or something? Do I need to wait longer for this stuff to dry? Perhaps if I used a fan to blow on it or something?
Please help! :)
