I've done some extensive research into LED hoods now.

I'm not going to spend agrand on a light fixture, even if it was for my car. So I've taken the time to learn that the wavelength of light for PAR required for SPS ald LPS ranges from 400nm to 700nm. Most blue LEDs emit light in the 440-500 range.

For instance, the blue LEDs in the AI hood emit light in the 470nm range

I found a nice new 120 watt hood on ebay with dimmable controls
the specs are:

28 ROYAL BLUE 455NM LED'S

27 COOL WHITE LED'S (14K)

BRIDGELUX LED'S

will this work for LPS and SPS?

Is the wattage an overkill on a 28G JBJ?

Overkill in my opinion, but you can always dim it.
