Lighting Hydrostar LED... Anyone familiar with them??

[SourDeezDC]

I came across a Hydrostar LED on ebay recently that verysimilar to the 5w Mars II but the price for their 600w unit is extremely low. Has anyone used an LED from this company before, and if so, what were your results/yield like??

I will be trying these in mayb a month! But their name has changed to SunSpect though .. Idk why! My buddy grows with them... The 600 watt led... He has 8... They have been using them in their bloom room for almost 7 months without a issue... No fails... Nada... Think I have a few pics of his girls he bloomed
with these leds! I'm trying to myself... Was either goin to try the old Mars Hydro 600 watt or the SunSpect 600 watt... The SunSpect has to cooling fans vs one with the Mars Hydro... The optics lens is 90
and 120 degrees... 5w diodes so we're getting good light penetration... Can't Daisy chain em like with the Mars 2... But they work good for me to buy them! Definitely will be ordering mine!

Thanks James for the encouraging review... I bit the bullet and purchased the light yesterday and it'll be delivered next Wednesday, just in time for my purple kush which showed her pistils earlier this week and my sugar black rose.

These lights are now being sold as ViparLED also.

They don't look bad for such a price, I'd probably buy this instead of Mars.
Only thing I find kinda funny is the wattage. They call it 600W while it draws less than 300W. The name 300 would be more accurate I think.

Any update SDDC?

The Epistar 5 watt LEDs must be real crap. light makers were driving the 3 watt chips to 50-60% of rated power yet they drive the 5 watt chips at 45% 0r less. They don't want chips burning out and losing face because of it.........

I have 4 lights with 5w diodes, and have also noticed the lower driver draw, which in an idle moment sent me scampering all over the Internet looking for a technical explanation, but didn't really find anything that satisfied my curiosity.

But I can say they are not crap IMO, and if they are, it is very decent crappie indeed. Take a look at my journals, links in my signature..... Most of the mayhem there has been produced by those 5w diodes.

I suppose, but don't know it as a fact, that the lifespan and gradual fading is prolonged and reduced respectively, by driving the 5w diodes at a slightly lower actual wattage than 3w diodes.

Over to @pop22 ...... I can handle any flaggelation...... And I know he is delving into the finer details of LED tech with relish.

The trick with underdriven leds is longer life and better efficency.
A led, when driven on nominal full power, produces its 100% of light while at half the current(50% of power) it still puts out more than 50% of possible light, so it's actually more efficient compared to the same led at full power.
However this can be used best with COB leds(also smaller epistars).
I hate when the manufacturers still advertise the led's max power which is never reached. At least put on a dimmer, it can't be that expensive to make.

What I meant is the fact that they either can't take a 50-60% power load, or the light makers are hedging their bets on life span. I'm not saying they don't do the job they are targeted at. If Cree can build chips that run at 100% with the same life span, why can't these do 50-60%? something is fishy when you buy a light with 5 watt chips that are run on 2.1 (-/+ 5%..... ) watts... or they are using chips that should have been binned rejects....
Wish I had a PAR meter. I'd love to do a side by side output test between a 5 watt chip light and a three watt chip light running at the levels used in these grow lights.
