No. LED’s have the added benefit of getting more efficient the more dimmed they are.

it alters the sectrum a tiny lil bit, but nothing you have to worry about, its maybe a 100 kelvin, so low i never worried about it.

yes but you need to consider the driver gets less efficient

The real question should be "does typing in all caps actually help get your point across?"

PWM? Can you explain?

PWM pulse width modulation. Basically when you analog dim your LEDs you are giving them less current and thus less power. When you dim with PWM you are making the light flicker (turn on and off really fast) anyway it happens so fast you can't tell it's happening. But with this way the more "off" time the dimmer the fixture will be. But the spectrum stays the same because the led gets full voltage and current all the time it's just for short bursts.

But even with analog dimming the spectrum really doesn't change appreciably.
