Ok, never mind. I wrote them an email to see about getting a new video and this is the reply I got back.

"Yes, they are AWESOME! However, to replace 1 1000 HPS, it takes 20 Red and
10 Blue Lights which translates to around $3500! WHEW! It is good to make
the one time investment, but not for the faint in the pocketbook.

Thanks, I will let you know!"

That could still be affordable if you aren't going for the equivilent of 1000watt HPS. I guess for a small grower with a 250watt HPS it would make sense. Also, from what I read it seems these work best in conjunction with normal lights. I will keep pumping them for info.

Peace
