Advice on LED lights

[Weezard]

Hey Weezard,

Have you ever seen this model of LED.

Kessil LED Grow Light


If you do. Do you have any opinion on these?

I've read their site but have not used their light.

The science looks good and the packaging is nifty.
However, at the price per Watt, I won't be trying them anytime soon.
IMO it would take 4 of them to even approach what a 400W HPS will produce.
So, $1200 seems too pricey
Just my opinion, I have no first-hand knowledge on these.

Aloha,
Weezard
