am using a philips r7s 4K metal-halide light 6000Lm 70W ... but best 'reliable' led brand I found, still in my basket, is pultry 2000Lm
https://www.amazon.co.uk/gp/product/B075ZZWC65
metal halide cannot be dimmed, but the reviews on the philips do not indicate if it dims reliably (some led dimmig is rubbish independant of dimmer control)
hey're great none of this nampy-pampy multiple spotlights in the ceiling , just diffused light bounced off of the ceiling
... no reflections on tv etc. (if you don't watch in the dark)
the halogen ones are omnidirectional, so you loose some in the reflector, so maybe you can get away with less on the led directional ones
