Mike And Me Photography - A photo for a Star Wars-fan friend. This was shot at 35mm on a 1.5 crop ratio and lit both practically (the light-saber is "functional") and via a nearly-unmodified RGBWW COB LED.

May 22, 2025 12:07pm RGBWW = Having red, green, blue, warm-white, and cool-white emitters, providing a wide range of output tuning. RGBWW lights provide color convenience without sacrificing fidelity when wanting to operate in the "white" range. The downsides are that less of the emitter array will be employed for any given setting, along with somewhat reduced brightness relative to wattage rating.
COB = Chip on Board. This refers to the LEDs being integrated into a circuit board as an array en masse. It results in significantly higher power efficiency (and, often, therefore brightness) compared to groups of individual LEDs. Also, it allows for better cooling, with the whole array often being mounted directly onto a large heatsink ahead of a fan. Of relevancy here, COB lights, because of their dense emitter array, are generally used with conventional modifiers, in contrast with large LED panels, for example. In this case, I *think* I just had a 7" standard reflector on it, but I'm not positive.
LED = Light Emitting Diode. A color-stable, efficient, cooler-running, more compact, and long-lasting bulb-like technology.
