TX LED Heatsink heatsink+120 degree lens 310

was using my own dyi sinks tried this one brought down the temps alot. screws r included all screw holes r perfect. every thing is perfect. will save u about 2 hours of messing around with diy sinks and is literally better thn what u might make. really happy with this.

The Aluminium Heatsink & Cooling Fan was paired with a cob led light source and dissipates the heat well. I substituted a 9volt power source in place of a 12volt to lower the fan noise. It still dissipates the heat with no problem. The fit to the cob led was perfect, be sure to use a little heat-sink compound.

I am very disappointed that I Received a unit with a manufacturing defect such that it cannot be assembled. There is seemingly zero quality control otherwise I can't see how such a gross error could have passed unnoticed. There are four machine screws which are supposed to thread into four corresponding tapped / threaded holes through the front face body of the heat sink; the screws are used to attach the lens and LED assembly to the heatsink. The item I received had holes drilled in the correct face locations in the heatsink but every one of the four heatsink's screw accepting holes were much too large for the supplied machine screws and so the assembly couldn't be done. The machine screws themselves seemed as if they were of a reasonable diameter, threading, and length and I couldn't find other machine screw sizes in my tool box that would fit the heatsink holes so maybe the heatsink drilling / tapping is incorrect or maybe there is another somewhat larger diameter screw that should have been supplied. I ordered two units and the first one assembled as expected but now that I tried to use the second unit it is found to be defective and unusable due to poor quality control of the manufacturing / testing / kitting process. These products seem overly expensive for what they are in that a cheap extruded heatsink, a cheap lens, one cheap stamped metal bracket, and a cheap fan are sold together; the value add is supplying a "ready to assemble and use with only a screwdriver" kit of the items that match the LEDs with the only real customizations of the raw parts being the lens holder bracket and the drilling / tapping of the heatsink face in the four locations needed for the bracket to attach. So probably worth the time / effort savings to buy vs. self-making a custom assembly if someone doesn't have a basic set of aluminium working tools, but if the sold units won't reliably "just work" in assembly then it is pretty useless and one would be better off just buying a generic heatsink-fan assembly and mounting the LED / lens in a generic way. The good thing that I can say is that one out of the two units I bought worked "out of the box" without a problem unfortunately since they looked about the same I didn't notice the mechanical threading / screw problem with the second until now when I trird to use it. So I'd have a more favorable review of this product had 50% of simultaneously ordered units not been defective out of the box. The supplied fan I received isn't particularly quiet when run at the nominal rated +12VDC input compared to others that are available so if you'll be in the same room as the operating light then perhaps the fan noise may be a concern. The heatsink face isn't particularly thick (prior to the depth where the fin slots begin) so I am skeptical about how effective it is at heat spreading since the area of the heat sink face is significantly larger than the LED device so I think it would run cooler if it had a better heat spreader design. I haven't measured the device hot spot temperature yet but I can say that on my working unit the heatsink / fan is at least somewhat effective at removing some of the operational heat. In ~25C ambient environments, the heatsink temperature in operation gets warm but not hot with a 30W device heat load and the exhaust air from the fins feels not much higher than ambient temperatures. Possible improvements I can think of: 1: Thread the screws into the holes in the bracket and the heatsing as part of the testing / kitting process so there is 100% guarantee the mechanics can be assembled correctly. 2: adding some means of air exchange between the space between the lens and the LED would probably help trapped hot air escape by convection and help cool the device's hot spots. 3: Show some thermal camera images with hot spot measurements of all sides of the unit operating after being run for 30 minutes in 25C room temperature with a 30W LED to show how effective the heat sink / fan is. 4: I don't recall that any thermal adhesive or thermal grease is supplied with this product, it seems like a small tube of thermal grease could be supplied or suggested for the LED to heatsink interface; I happened to have some already. 5: The product specifications should indicate what the screw length and thread diameter / type / pitch should be since it would have made it easier for me to check whether the screws were correct or the heatsink tapping/drilling was incorrect. Also it would make it easier for somebody to replace a screw if they lose one in the future. 6: In the case where someone might want different beam angles than the lens options offered it would be nice if the manufacturer linked to some alternative compatible lenses and provided the lens diameter / thickness specification that is compatible with the supplied lens holding bracket. 7: Since the heat sink is an extrusion I don't see why there isn't an option to have product variations for 1 LED, 2 LEDs, 3 LEDs, 4 LEDs in a line or maybe 2x2 grid, 8 LEDs, etc. mounted side by size to a longer variation of the same or some similar sort of heatsink. 8: An option for a quieter fan (and as may be appropriate one with long endurance design specifications would be nice -- I didn't check the fan to see what kind of bearing / drive design it uses yet). 9: Actually I know some people would be interested in passive cooling options so another variation could be one with a significantly larger heat sink that is intended to be used without noisy fan based forced air cooling at all.

Bought this for my daughter, because the lens cover also covers the electric leads on the LED which wasn't as big of a concern on my grow lights. I'm still going to need to cover everything better, but the lens, heatsink and fan were all better quality than I was expecting, and I realize now that I should have just ordered this for myself in the first place instead of DIYing the whole thing because this setup with everything predrilled and threaded saved a TON of headache. I'll be getting more of these in the future. Also, this heatsink DOES work with the more rectangular nagulagu COBs that I ordered, not only the square ones that Amazon recommends / can be ordered with it.
