if you want, I think most will run more wattage than that by quite a ways
DreamChip build

I like it thanks for sharing I will need to look into this very soon.

Yes it can but the effectiveness will go down (PAR/insert Watt)
See these diagrams:

These numbers are surprising. From my experience with LED's when in there recommended operating wattage range the higher the wattage the less effecient they are. While they may give off more light if you divide the output by wattage it is higher in the mid to lower wattage ranges. You first grasph suggests just the opposite of this.

This is looking great. I'm following along as I curious about these chips.

BTW ... where can we get these, i have searched dream chip and get no results

With all respect TropTrea - both graphs show exactly what your experinces is - higher input - less effeciense. From the first graph (the 100 LED chip) at an input of 80W - PAR 261 -> 3,26 PAR/insert W, input 100 W - PAR 315 -> 3.15 PAR/ insert W. Input 200 W - PAR 540 -> 2.7 PAR/ insert W. Graph 2 shows it also rather clear.

Yes after looking closer I see that. I'm used to seeing the x axis being the horizontal axis or in this case wattage, and the Y axis of verticle axis being the result or in your case PAR. From this reasoning your axises are simply reversed. It is a common thing between American and European diferences in charting.
Nothing major to update - I'm still happy with the way DreamChip works and I'm about to install the other one as well in order to increase the amount of light for SPS corals.
Acans are loving the current light, as are some algae which started growing on the bottom the other day (tank is still relatively new with 3.5 months).

Have all my stuff to start my build of my 2 100w dream chips, meanwell drivers here finally next week, not sure if i will post the build of my light or not. Took awhile to put it all together...., finding and paying for it....budget and all...lol.
Hey all, sorry if this is a slight hijacking, but I have a 40g breeder that is close to being set-up again after moving. I've converted my 29g sump into an all-in-one to keep my corals and fish happy while I work on the display tank and stand. I have 2 meanwell ELN-60-48D drivers that were lighting a super cheap 3w array that I did not like (intensity was low and color was too warm). I was wondering if I could use these drivers to run 2 50w dreamchips that are out now and if this would be enough for sps, clams and anemones. I have a 24"x4.25" heatsink these could be mounted to with fans inside the canopy that sits about 10" from the water. I'm looking for a 14-16000k look but am interested in 2 chips with a large spectrum.

Well here is the heat sink i am going to use with my 100 dream chips Accelero Mono PLUS, i would post some pics of these with the aluminum heat sink adaptors
this is what i have for heat sinks and chips

here is my aluminum adaptors to attach my chips
installing heat sink adaptors

picking up meanwell drivers tomorrow
Work in progress

I use the same heatsink, you dont have to use an adapter just bolt it right to the heatsink it covers plenty

well i did it this way because it also allows me to bolt it to my aluminum housing
