Sunshine Systems 90w LED -- any thoughts on it?

I was wondering if anyone has had some experience with this LED?

I've been extremely happy with their 28w Grow Panel for vegging, so I was thinking about trying their 90w with a little HPS combination for flowering.

Has anyone had any success with this light? It's a litle pricier than other 90w LED--success stories?

I was also wondering, if there was any heat with the 90w..the 28w had none. Some LEDs are a lot hotter than I expected.

Thanks!
