Yeap ,in automobile head-lights ,they surely do ...
Other than that ,nope.
You do not want to talk about any nutritional substances of edible fruits/leaves
and the potency of medicinal herbs ,when grown in artificial environments under HID lights versus LEDs ...
Not with me ,at least ....
I've at my arsenal hundreds of researches and papers ,to
dismantle any of possible arguments ...
So...
Be cautious on how you will-if you wish so- proceed further on this conversation ,brother ...
HIDs do grow edible and/or medicinal plants ...
And in some cases with better yields than of LEDs ..
But ...without taste ,aroma ,anti-oxidants ,vitamins ,flavonoids,terpenes ,THC ! , etc ...
They do grow "empty " vegetables ,fruits and flowers ...
Compete with solid state lighting ?
Not even close enough ...
Your turn ..
Cheers.
