1. The round 4 inch Downlight Light Engine, 6 inch Downlight Light Engine, and 8 inch Downlight Light Engine is idealy used for 4 inch, 6 inch and 8 inch LED Downlight and LED Can lights. They utilize efficient and economical Seoul 2835 LEDs. The efficacy can get to 200lm/W without lens and power supply loss. After lens and power supply loss, it gets To 160lm/W. In the market, the most LED which is used for 4 inch Downlight Light Engine, 6 inch Downlight Light Engine and 8 inch Downlight Engine is 3030 package. Because a lot of worldwide brands use this LED a lot, it sounds premium than 2835 package. In fact, Seoul's 2835 has higher efficacy than 3030 from a lot of big brands.
2. Our LED Downlight Light Engine uses Aluminum board instead of FR4 board. This helps heat dissipation since LED Downglights and Can lights are normally lit for long hours a day. The main reason to cause LED Product failure is the heat is not handled properly and the capacitor failure of the power supply. Of course, Aluminum Board to make a high quality 4 inch Downlight Light Engine, 6 inch Downlight Light Engine and 8 inch Downlight Light Engine can't completely solve all the heat problem. The fixture heat sink is necessary to dissipate the heat as well. We make LED Downlight Light Engine, so we make sure our part is doing well before they get to our customers' hands.
3. Our current 4 inch Downlight light Engine, 6 inch Downlight Light Engine and 8 inch Downlight Light engine probably can't meet all your applications. Other size LED Downlight Engine can be tailored to your needs as long as you tell us the specific voltage, lumen output information. Here I only talk about Round LED Light Engine, other shapes can be customized as well. If you need other brand LEDs, we can help with it as well, for example, using some Chinese Brand LEDs, like Refine's or Hongli electronic's. For some products, probably it is unnecessary to use top 1 line brand LEDs. Chinese brand LEDs are enough to achieve the result. This is a nice way to lower the cost while delivering satisfactory result.
