Any one really good at working on LEDs? I have a 200w Evo Im having trouble getting running right. On friday I replaced all the fans in my 2 unit as they had slowly start to fail and the wires were snapped off at the motors on a few of them and a few other bad connection there sure not built for saltwater tanks thats for sure lots of corrosion inside cost about $100 to fix and a days if time. Well heres where Im at on the one unit the fans fire up to full speed no problems. On the other there running at maybe 40% and on this unit I did notice on both of the little orange covers over the drivers on just the blues they had started to get hot and melt from the lack of air from the fans going out. I know the fans come on at full speed with the blues but why not 100% on the one? Ideas? The one thats working right you can touch the fixture its warm to the touch. The other is super hot.


Thanks,

Levi

Are they under warranty?

Nope. Im hoping I can fix them and get a little more time out of them but parts are next to impossible to find. Kind of learn my lesson on buying China leds wont go that route again it will be either a dyi or kessil's or maxspect setup something I know can easily be serviced.

You will have issues regardless of where you go once they are 2-3 yrs old. I know 89Delta is a wiz at fixing older led units. He has fixed mine and a bunch of others. I would PM him for a quote. As far as advice I have none as its way past what I do which is to replace burnt out leds. I have fixed 3 EVO units that are way past warranty period and all they needed were new leds to be back to full brightness.

Ok I will have to pm him. I get that everything will have problems I just don't like you can't get parts for them. The fans I replaced had cheap screws that should have been stainless steal as i had to cut them out and the solder connections were poorly done had to redo some of those. For being 2 and half years old and costing $500 each they should last a lot longer than this and at lease be serviceable.

Oh I agree that for age and price that one expects them to hold up better. I think its why many manufacts have gone to plastic.

I have never liked the Chinese leds with big markups. Notably reef breeders since their markup used to be massive compared to wholesale cost and the cost to change the spectrum of leds is free and they claimed all this research went into it. At this point anyone can do about 10min of googling to find out what color or spectrum bulbs are best. Also with Chinese eBay units going for 88 bucks new with USA warranty and full spectrum there just isn't a market to sell them for $500 anymore.

For 88 if it lasts me 2 yrs then it was cheaper than MH bulbs and electrical cost so I'm OK if it stops working.
