The kind is listed above. The brand name is Kingso. I've added 16 more chip as i was only running 20 chips for 2 weeks prior. Ill tell ya my expectations are met for sure so far. They do get a lil bit warmer than running 20 of em like before. But the cooling pad is working pretty good for dissipating the heat. Lights seem to be working great. And the girls are definitely getting bigger. Glad i went from cfl to led for flower
Never heard of it. Checking it out nowand it looks really cool and effective. I do have blurple supplemental lighting on the sides of the box. the red is 625 to 660nm.
A couple a questions...so what sizes are your square stock? How did you mount your LEDs to your square stock? And the cooling...does it just blow along the sides of the square stock? And when you say hot, have you measured the temp of the aluminum square stock at full power? Thanks.
Thanks for stopping by. When i was just running the 2 bars 20x 10w chips w/2 ac fans with 203w power supply i could hold my hand on to the bar for atleast 5 secs until it felt hot and when i would turn off the light it was cool to the touch within a min. Temps in box stayed around 75. Now with 36 of them i can touch it for atleast 2 seconds and then it feels pretty hot. Temps in box are about 82 now. I used artic silver thermal adheasive. The aluminum bars are 1/8"x 1" x 18" and the smaller ones are 1/8" x3/4" x 18" the cooling pad has four fans i just used 2 1inch velcro strips to hold it in place. The fans blow upwards pulling the heat. For the chips says max operating temp is 176f 80c. Ill look at getting a radar gun to use just stick a sticker on the bar it should work. Or a thermal couple
Thanks. I have used 2" square tubing and Vero 18s with good success. I put a 2" fan on one end and it kept things cool...but like yours, with fan off it wasn't to long before it was really uncomfortable to touch. Do you have any way to measure light at the canopy?
Nice. Ima redo my venting to. Box remodeling today. Sounds like u have a nice setup. Have u tried thermoelectric cooling strips. They r 1.5 x 1.5 perfect size for your square tubing.
Let's not forget that with peltier coolers while one side can form ice the other side will just about boil water at the same time, hence the need for a heatsink on the hot side of the peltier.
Yup, you gotta remove that heat somehow or the peltier will literally melt.
Slow down the water flow and it may be more effective.
