2 Optimal Heat Sink Solutions
The NTC (= Negative Temperature Coefficient) thermistor and the PWM (= Pulse Width Modulation) control are combined to work in an intelligent mode where the inbuilt fan could monitor the COB light temperature itself and adjust itself to cool the fixture properly. When the fixture is overheat, a self-protection mechanism would initiate to prevent any accidents.
28dB Quiet Overheat Fixes
The copper heatsink based dissipation regime runs to transport and dissipate the COB thermal energy quickly and efficiently. The upgraded FDB (= Fluid Dynamic Beating) built in the cooling fan is much more quiet, significantly decreasing high-frequency mechanical noises. Under this, the CL220 lineup is able to keep a balance between high output (= 220W) and low noise (= 28dB (±2dB) at 1m) even when the temperature outside reaches 35?.
