I decided to look at ebay out of curiosity to see what LED's are being offered now. It is amazing what you you can find in the $125 range, with dimmers and lenses. I may order some just to have back-ups.

Any opinions? Are they junk?

I currently have 6 total LED fixtures, and they are all Chinese, I feel like they do well.....not great.

The earlier versions of the Chinese led units used the smaller dies on the LEDs so they weren't as bright. These days the dies have become larger and the lumen output has become higher. For deeper tanks like yours you defiantly want optics on the units to penetrate deeper. I can pick up boxes of 100 pieces of optics minus shipping for around $34/bx if your not happy with the optics you choose on the new units.

This is the Unit I have. It's a manufacturer photo although after getting new LEDs to replace the ones I used to fix 3 of Joe's other units and finding a 100W Driver it does the job very well just running on one channel without optics although i'd like a little more blue.But since I only have one channel going I can't dial in the color.Here's what everyone should be looking at when not using any optics.A good LED density of around 24 LEDs per square foot for 10" to 12" deep tanks, 36 per square foot or 12" to 18" tanks and 48 per square foot for tanks 18" to 24" deep using a nominal drive current (650mA-700mA).Never use the max rated for the LEDs, which for Bridgelux is 700mA-750mA. By running a lower current you're going to get more life out of the unit as well as the LEDs while keeping heatsink temps down. For tanks deeper than 18" my recommendation is to use 90 degree optics which would give better PAR readings. 60 degree optics can be used as well but would need to be mounted a little higher so a "spotting" effect or coral bleaching doesn't happen.

I think that unless you are going to buy Ecotech Radions or AI or a brand that manufacturers their own and have spent tons of money in RD for the units then everything else is made in china and are all basically the same. I was shocked when a month ago another scmas member pointed me at a website and I started finding these lights that are sold with huge markups and are actually all the same unit made from the same manufacturer in china. sure the manufac will tailor the unit to how you want it to some degree, bridgelux/Cree/epistar etc but its still the same unit made from the same place. A ford is a ford is a ford in my opinion and a Lexus is a Lexus is a Lexus. Buying a unit from the manufac for 140 plus 40 shipping and selling it on a website for 370+ is ridiculous.

I was able to check out 89delta's unit and it is nice full spectrum. I really liked his custom controller that he is able to increase in super tiny increments instead of in 1%, it was so smooth of a transition.

for a 40g breeder would you go with the IT2080 or 2060?

89delta
10-08-2013, 05:37 PM
Me personally I'd go with the IT2080. Soon as I get my 40 fixed and a stand I'll be switching to it. But either will work just fine. The 2060 will have to be higher and will give less of a par reading.

"Full spectrum" is over rated. Really a 2:1 blue:white ratio is where you want to be. Optics are nice but not necessary. Dimmable is important so you can adjust intensity in the tank without raising and lowering the light.

A built in timer is a nice feature but if the dimming is not controlled by the timer its sort of pointless. Besides that if the internal timer craps out on you the fixture will be rendered useless unless you bypass the timer.

There are dimmable fixtures available for about $100 ea. I just webt that style and use an external timer.

It's funny that this is being posted on after all this time, and I literally just got 3 of these in the mail today. x3 for only $263!!! I hung them and tested out the dimmer feature.....WOW!!! So much better than my chinese 2:1. You can really tweak your color spectrum to your liking. My 2:1's were too washed out with the whites on, looked almost yellow, and made everything in my tank look brown when everything was on. For that reason I only ran blues, so I was cutting myself WAY short on light/wattage. My new "full spectrum" dimmables, I was able to run both blue and white channel and get the perfect color for me and the colors still pop and don't appear brown.

This is my opinion based off of the fact that I have now owned both chinese options......and my old 2:1's I actually had to have delta change out some of the white LED's with blue and red to get a better color spectrum.

I say, save yourself the headache and get these! :)

Can you change individual channels? I have the green element white/blue 120w, added an external dimmer and timer, but I would really like to control the individual channels and have 20Ks in the color mix ---and get the colors to pop better. I added a used current marine..and love the sunrise/sundown feature. Or is there a way to add an external controller? But then how do you separate the channels? Soooo, I thought, and all in one for NOT $500 bucks would be great.
Oh, and I would like to mount them pretty low on the tank so I don't get too much blinding, so 120 degree optics. Can you change out the optics on those Chinese contraptions?

Stated that it is full spectrum - their specs state othewise.
stated 150watts - at 680mv each led is 2.4watts x 52 led's = 125 watts
Price seems to be a bit high compared to what is available on ebay.
Dimmable is very good feature. The timer is a plus.
Look into the LED's tha Levi got or the one that 89Delta is selling. There are other vendors on the forum. Look through the sponsors websites.

UPDATE!!! Like I said, I purchased the same lights as Levi posted ^^^ and I freaking love them. After experience with lights that have no optics compared to the new dimmables with optics, I have to say that I love the optics. This may seem hard to believe, but the colors that I am getting out of ALL of my corals is ridiculous and after just one day of having them. There are colors in my zoas/palys that I haven't seen since a week after I bought them. I have around 10 acan frags that looked great when I bought them....then after about a week in my tank they won't inflate. The acans have been in my tank from anywhere from 10 months to 2 years and have always stayed closed and bland in color. After one day with optics (my tank is 30" deep) they are starting to inflate like they never have in my tank, and I'm hoping/thinking that they will only inflate more with time. You may be like me and think that acans don't need much light but mine prove otherwise. Blastos looks better, sps is looking better, frogspawn and hammers are looking better.

Long story short, I wish I had some before and after photos, but if you have ever seen my tank and you see it again you will notice the difference!

These are the ones that I got, but we have some sponsors with great dimmables with optics as well. Bubba's Guppies (delta), coral xpressions (bush), and reef koi (chris) to name a few. Highly recommend optics and I can't stress that enough. They penetrate the water so much better than ones without!

Levi, do you mind posting a pic on how you have them set up?
Those don't have a timer right? so they don't dim automatically? Ugh...all this research got me royally confused. There is a insurmountable amount of differences from one unit to the other...

no timer or auto dimmer. I run them at 100% so since they have 2 cords I have the whites on a timer and the blues on a different timer. I really like that they daisy chain off of each other so I only have 2 timers and 2 plugs going to the surge protector but it controls all my lights. I am working with 89Delta to get the same touchscreen controller you liked on the expensive unit and seeing if it can be used on my units. I bought 4 of them, use 2 over my 75g, 1 over a 40g and 1 over my frag tank. The controller will add cost and honestly for time and effort involved to get a fully controlled unit like what you posted, I will not be saving much, around $40 per unit to do it myself with 89Deltas help. I have the timing down and I run at 100% so I really do not need the controller it is just a luxury purchase that I WANT, not need with these lights. I am really impressed like Cody with how my clam and corals are coloring and how fast they are growing. Some of the zoas I have, I have only had in the tank for less than a month and already have many new baby heads sprouting as well as some have 2-3 full heads that are new in just 1 month. I never had that type of growth with my t5 but that is most likely because it was the wrong spectrum and underpowered compared to the LEDS. They say 165w but they are not running at max power from the drivers so its more like 120w when calculating it all out. Mine came with 90 degree optics and were slightly more expensive than the ones with 60 degree optics. Also dont look at the picture because it is not accurate, look at the specs of what they say are on the units. The pic shows 4 UV bulbs and these lights do not have UV. I will be modifying my lights to get rid of the low end warm whites and replace with cold white 10k or 14ks as well as changing the blues from 460nm to a more royal blue 445nm and adding UV.
