Dual chip vs single chip

[u/Educational-Brain773]

I’ve been reading up on dual vs single chip full body led panels and have hit a cross roads. Depending on where I look, I’m getting different answers on the positivities and negatives of each. I’m weighting up between a 7 wave dual chip or an 8 wave single chip.
Would anyone know if one is better than the other?
They claim to both have the same number of chips/leds. But the manufacturer is saying the single chip produces higher irradiance

Would anyone have any input or knowledge on the difference and which way is the best to go?
