The cost performance of our this 100W 5600K COB LED is better than YUJI COB LED. YUJI COB is too expensive
Please Note: this listing is multi-option products, including 100W/200W/300W COB LED, please choose which one item you need to buy, you also put them into your cart one by one, and pay them together, we will ship them in one package together to you.
Features of 100W COB LED:
- High Power COB LED 100W Daylight White. Color Temperature: 5400K-5700K (5600K). Material: Copper Brackets.
- CRI Ra 95+. Working Voltage (V): 34-36 Volts, Max is 38V. Luminous Flux (LM): 10000-12500 LM. Current: Rated 2.5A, Max 2.8A, please note: in order to protect COB LED not burned, the working current must be limited to 2.8A, can not over 2.8A, hope you understand.
Brand of LED Chip: Citizen. Working Temperature: -30-60℃. RoHS Compliant and UL recognized component.
- Note: It will work more than 30000 hours if the working temperature is less than 60 Degree Celsius. So, they need to work wih heatsinks and Thermal Silica for cooling and heat dissipation, otherwise the COB will be burn broken due to too much hot.
- The cost performance of our this 100W COB LED 5600K is better than YUJI 100W COB LED.
