• weight (without bracket) 695 g

LED Cree CXB2530-0000-000N0HU440G, characteristics at IF = 800 mA, TJ = 85 °C:

• CCT 4000K
• CRI min 80
• Flux 3955

• input voltage: 6 - 26 V, recommended 24 V
• output current 0.01 - 1.5 A
• power: up to 60 W
• save settings to flash
• RS485 ModBus for calibration and control
• output power is limited when temperature is greater than 85 °C
• output power is linear limited if the input voltage is less than 15.0 V, At 6.0 V maximum output current is 0.3 A
• smooth button control from 10 mA to 1 A
• temperature compensation

Driver schematic:

• use 5 pin connector, pinout:
  • 1 (white) - GND
  • 2 (red) - Power +6-26V
  • 3 (brown) - RS485 B
  • 4 (violet) - RS485 A
  • 5 (black) - Switch button

It works according to the formula: $setpoint = setcurrent * (termalThreshpoint - temperature)^2$
The work of compensation on a real hardware is shown below:
