100W LED Multi Chip

StirCrazy · #1 10-27-2012, 02:39 PM

I don't think thoes are good color combanations, first they will be very blue and second they are missing colors that will bring out the reds in your tank.

now if they replaced 2/3 of the cool white with a nutral white I think that would be a lot better, but as they sit I wouldn't waist my money.

I do like the idea of a 100 watt LED as you could do smaller tanks with 1 small pendant. you can pick up a 100 watt 4500K chip for about 60 bucks so I kinda question the price of these also.

I was wondering if you could put different colors on a chip, now I know you can. I have a high school buddy who lives in china and is the ceo of a large exporting company who also do LEDs I wonder what kinda deal I could get for us.

My kessil a350 s. aka. Tuna bles are 90 watt multichip LEDs made by their sister company Dicon.

I am eagerly awaiting some longer term results from using these 100w emitters. Sounds like the second GB was started before everyone in GB1 even got their emitters yet.

Unfortunately, if they need to be mounted up high, Irene would most likely never let me use these 100w pendants since she worries about how bright the lights will be to the human eye (we have two little girls and my 10w emitters have to be mounted low and with full reflectors to kill the glare). I'd probably have to mount it nearer to the front of the tank and slightly angled back so that the glare would be against the wall, I guess.

I imagine that once there are some longer term results from these First Adopters and it becomes more common to use these multichips, the price and variety will hopefully reach a point where they will be more available and attractive to reefers.

I'll have to swing my Burgess' place to check out his Kessils with the 90 watters to see it in person.

I think if u use lenes you can mount any hieght you want, some are mounting as low as 10" off water, and others higher up, think just depends on weather you use lenes or not. The colors that were picked for the dream chip are the colors that some reefers are already using, and was decided by what they can do for the corals. I posted the link here for those that are interested in joining the group buy. You will never get everyone to decide on everything....lol, what makes us human. There are so many options out there for LEDS that well you can build what ever u want. I am looking at the chips as my main light source, and possibly adding other colors later if needed. Face it with the cost of T5 bulbs and metal halide and how often you have to replace, where as Leds if powered right should last 30,000 hrs min.

I actually like the mix in these "Dream" emitters. Similar to what I would choose.

These would def. be very nice and I would want one except that I have almost no skill in this area so I would not know how to put them together

Not really that much to doing up just one of these. You only need a few components & some sort of mounting rig. The chip, a large heatsink with fan, a driver and hookup wiring are the main requirements. Since the LED is a DC device it's pretty simple to hook up with only two wires, a positive & a negative. The large heatsinks with fans for these chips also need two wires hooked up, again, a positive & negative, usually 12 volts.

A search on the net on builds of this nature will give you plenty of info. But, yeah, if you're unsure about diy something like this, then it's best to look for something already manufactured, such as a Kessil.

EDIT: Here's a how to vid on utube

The pic posted earlier was taken with my phone so it looks super blue. These pics are more realistic but still more blue than in reality.

I really don't get the popularity of 4500 & 4100K yellow/green chips. LEDs are generally "whiter" than MH of the same advertised colour temp so they are like using 3600k MH. For the past 30 years fluorescent and MH users have abandoned anything below 10k, so what's with the retro yellow/green chips?

Warm white chips have very little blue and lots of green, but they are also weak in reds. If you want red, then add dedicated 660nm red chips. If you want green, 7,500K Cree chips are extremely green as they are designed as desk lamps.
