ElectronicsPrinter I would guess that this light puts out about 700 lumens in the sensor-activated high mode, similar to a 60 W incandescent, with a wider beam pattern (this is the 6 COB version). Didn't pull out my Lux meter, just using my calibrated eyeball. The constant-on illumination is about equivalent to a 15 W incandescent, enough to see where you are going in the dark.

ElectronicsPrinter This LED light uses AAA batteries. It does not accommodate charging of batteries in the flashlight.

ElectronicsPrinter Apply power to the module Hold the learn button for about 8 seconds When the LED light turns off the module is reset to factory status

ElectronicsPrinter I would think so. Connect it to a normally-open (NO) relay contact.

ElectronicsPrinter This LED light panel has a color temperature of 6500 to 7000 K, no warm light option.

ElectronicsPrinter The board operates on 12VDC. It can switch 10 amps at up to 250VAC or 10 amps at up to 30VDC. You can switch a 5 Volt device (using less than 10 amps), but the board needs a 12 Volt DC power source.

ElectronicsPrinter I have used it successfully to engrave flat plastic workpieces with the 500mW laser. Keyboards may have tapers, angles and curvature which may require multiple adjustments to the laser focus, i.e. you may have to engrave a section, stop, adjust the focus, engrave the next section. But, in general, yes, that should work.

ElectronicsPrinter Yes, the lamp has built-in magnets that attach to an adhesive metal strip that can be placed on any flat surface. The magnets are strong enough to secure the light, and it is easy to take off for charging.
