Specs on these lights are these, look at pg 20

From what I see, looks like there 45, unless i am not reading them right.
I just got off the phone with Mike, i believe we spent like over 3 h on the phone.
The time I spent with the guy, I felt i was talking to an engineer, not sales guy.
I should know, I am Maintenance Supervisor, and I deal with both the engineer and the sales types almost on a daily basic.
I even got on his case, because i felt no pressure of him selling the lights.
He is very knowledgeable in electronics, we talked about everything under the sun and then some, mostly different types of technology.
What Attracted me to his product was the way the LED fixture are built.
Trust me, i know. I use to build and final test 5 million dollars Etch/ deposition machines, with 3 axis robotics for a semiconductor company.
There is a lot of fine details with his units that most don't see. I am going to list a few.
1) Heat sink to a certain agree is passive, LEDs are not going to go boom, if the fan fails, depending on the room temps, you got some time to deal with it, not like other LEDs Assembly's that are totally active cooling, he has massive heat sink on those LEDs.
2) Wiring, he is using Teflon silver tin wire, those wires will not melt or corrode, its the best wiring for harsh environment.
3) Each LEDs are are electrical power separated, if one goes poof, it doesn't take the whole line with it and the rest continues to work.
4) Power Supplies, any 13.5 v DC with the right current rating will work with his LEDs.
5) Any of his LEDs can be replace by an idiot well maybe not every idiot, lol, what does that mean?. If one LED goes bad, you just need to get that one replace, not have to shipped the whole unit out. It also means, you can upgrade to a newer type of LEDs if you need to.
6) Warranty for one year, and up to 5 years for LEDs if there are found to be a manufacture defective. Water damage of coarse voids it.
Like I said before, this guy know his stuff, just send him a email and talk with him you wont be disappointed and don't ask him a question if you don't want it answered, lol.
I place my order for 3 x 88 watt units, he convince me not to get the 144 watt, good chance i will not need them. But if I do need the 144 watt, i just need to buy four more LEDs and 1 board and my 88 watt is 144 watt model.
I will report once I get them in my hands. I can also return them, if i dont like them.
