Helios Crew Corporation (HCC) LED. 3w puts out 170 lumen @ 700ma.

I've been following this thread with interest as I'm still very much on the fence about how to light a 6 foot x 3 foot by 26-30 inch deep (haven't decided how deep yet) tank. After reading the whole thread, I'm still firmly perched on that fence.

i am just doing some finishing touches on one of the led module.
i will post a couple photos later.

Older thread here but wondering if there are some more pictures that people can add to this thread. I am still planning on building my DIY fixture but my house got stalled part way into the build and I've been preoccupied with that, and children and changing jobs...etc.

Any new pics people have of their LED's?

My 2 cents. Cost isn't going to be huge saving, like people have said and showed, cost of builds and electricity savings are going to eventually pay off the LEDS. But as also stated, people are assuming the LED's and drivers won't malfunction during that time (technically they shouldn't... but...). Same goes with MH too though, as i'm sure anybody using an old humming ballast knows.

The HUGE benifit in my opinion is the wave length on LED's... it doesn't change. No color shifting after 6 months like MH(even the best bulb will have some shift.) The output is at least 70% after 5 years of 12 hours a day use. Most people are underdriving their DIY systems, so they can increase to get that 70% back later on. Big setups are usually driven to max, but have sufficient cooling so that it won't matter.

People ahave been arguing the PAR rating etc, but PAR is a poor measure of what we need, most meters check all light between 400nm-700nm and give back the average over that amount. What we really need is the used wavelengthss since coral doesn't use an average from 400nm-700nm. PUR is better, but hard to measure. What you CAN see is the output of LED's on a wavelenth compared to what algee needs to grow. This is why i'm going LED's(not cree LED's or a good MH bulb/balast, but you can find wavelengths for both from cree's site and from sanjay's site, just a good general example)


Here's some links on LED's that should relate to this "tank pics":

Here's a pic of that tank:

I'm upgrading my tank and debating if i should keep my MH or switch to LEDs. My first impression of LED is fairly positive. I hate switching MH lights every year. The heat output is a big minus as well. I've been habituated to the cooling fan noise, but it is loud and annoying for others.
I don't see many commented this setup. I think the setup looks pretty amazing. How is your tank doing, Lampshade?

Here is my 72 3watt Cree, DIY, 36 XPG cool white, 27 XPE royal blue, 9 XPE blue, no optics, w/meanwell dimmable drivers, controlled with RKE ALC.
The first pic is the LED, the 2nd is a 4x54w T5 HO

Nice...good to see some more setups here.

2x E.shine 60w LED units @ 70% (acclimating)

Excellent value and no heat issues!
