Review: Great purpose built heatsink for LED COBs works perfectly for a 50w LED - If you are getting a bare COB LED light, driverless or not, this unit is a must to keep the light and electronics cool. The lens works great too, with some slight modifications for certain COBs. I could have made a DIY heatsink for less, but the time to drill the correct holes, tap and get screws didn't seem worth $24. The LED I used was a driverless 50w COB chip found on desertcart: https://www.desertcart.com/gp/product/B07GTMQSFZ/ref=ppx_yo_dt_b_asin_title_o01__o00_s00?ie=UTF8&psc=1 I measures the wattage and it's a true 50w. With the fan OFF, the heatsink got quite hot only after a few minutes. Some important things to consider: 1. Use decent thermal paste (has some old Arctic Silver 3 laying around), clean the back of the chip with rubbing alcohol, as well as the heasink surface. Put a thin coat of the paste on the back of the LED chip, spread with a razor or credit card. Mount and secure well with the 4 supplied M3 screws. (they actually supplied 5 of those for some reason). 2. On the back of the small reflector that coems with the lens, there are 4 raised bumps. These align with holes in several COB chips that require a driver. My COB did not have those holes, so I took a razor and shaved the bumps off off. That way it sits flush on the chip. The reflector is plastic, so that's easy. 3. With 12v on the fan, it's LOUD. I used a universal 2A power supply and set it to 7.5v. At 7.5v, the fan is virtually silent but provides enough airflow to keep the heatsink just warm to the touch. I had to do some soldering to make that connection. 4. If you have concerns about glare, get a stainless mixing bowl, cut a 53mm hole in the bottom center, then 4 more holes that line up with the screws that mouth the lens housing. See attached. It looks cool too ;) 5. For hanging the light, I put a string diagonally from one screw to another on the fan grille, then hung from that. Works great! After working with the first one, I went and bought a second. Yes, I would recommend this.
Review: Quality heatsink, with a lens - This heatsink is a must for a 100W LED array, othwise the chip would be destroyed very quickly.

## Questions & Answers

**Q: Do you offer a passive cooling version (no fan)?**
A: LOL @ those other answers. Modern LED grow lights are often cooled passively. No 25mph winds or heatsink the size of Delaware. *eyeroll* (I have 600w of LED for my tomatoes and peppers, manufactured by a famous company, all passively cooled. However, those go through extensive research and development. This could probably cool 5-25 watts of LED without a fan, but heatsinks like these are specifically designed for air to flow over them. The tight, tall fins just pass heat back and forth without air movement. A much different design of heatsink would be needed for 50-100w. You can get a very silent 80mm fan for not much money, $9-$16. Brands like SilenX, Arctic F8, BeQuiet!, or GeLid are options. Then you just need a 12v 1A power sully to the fan.

**Q: Can this also fit a 150 watt led chip?**
A: This heatsink fit 20W/50W/100W/120W ,If use for 150W we suggest choose this 2 models will better: http://www.amazon.com/dp/B01CTZ8X8Y  or http://www.amazon.com/dp/B01D1J1JFQ

**Q: I prefer something with passive cooling (videography) because fan noise is not acceptable. How many watts will it sink if fan is removed?**
A: As already mentioned, air movement accross the fins is what removes the vast majority of the heat. And, there are some extremely quiet fans available. They spin slower, so less noise.

**Q: Do you have an option to purchase without fan i already have 120v 80mm fans just need heatsink, lens assembly and screws.**
A: I am sorry, Our inventory in amazon wareshouse all include the fan.

### ⭐⭐⭐⭐⭐ Quality heatsink, with a lens

### ⭐⭐⭐⭐⭐ The Aluminium Heatsink & Cooling Fan works great
*by J***R on October 25, 2020*

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.
