Ando Posted April 17, 2009 Share Posted April 17, 2009 Very nice light! I'm interested in the group buy! thinking of getting the twentyK light. Great job Evil. Link to comment
evilc66 Posted April 17, 2009 Author Share Posted April 17, 2009 I am unclear on what details are about to be posted, but I *hope* they include details on the super-slim actinic supplement and the 20" led fixture. Guess what Tanque. Linky Link to comment
evilc66 Posted April 18, 2009 Author Share Posted April 18, 2009 Question for everyone. Would you prefer these natural silver, or annodized black? It looks like the Sunpod actinics are getting annodized from the number of people interested, and I could get these thown in too. The volume of parts will prevent there being any cost added (hopefully). The only thing that could kill this is that they are painted, and they may charge extra to strip. What do you think?

evilc66 Posted April 18, 2009 Author Share Posted April 18, 2009 I'll be calling monday to find out if they can do it. Link to comment
evilc66 Posted April 20, 2009 Author Share Posted April 20, 2009 These are now available for order in the LED group buy http://www.nano-reef.com/forums/index.php?showtopic=194886 Link to comment
Marteen Posted April 20, 2009 Share Posted April 20, 2009 I saw this on your group buy thread and it got me to thinking that you could do something like this in the same frame as one of those MH spot lights that they love on those Japanese tanks. I was cruising through the eco-lamps store and came across these: http://www.eco-sell.com/services/eshop/mai...15W〈=us Since they are running 5*3w couldn't the heatsink handle 5 cree XR-E lamps say with a really tight optic like 18 degrees for spotlighting on bigger tanks? You could set up a couple of these on a tank and get some nice coverage and get that all important streamlined look. Just an idea time for bed for me. Link to comment
evilc66 Posted April 20, 2009 Author Share Posted April 20, 2009 Could be a fun little project, but those lamps could be trouble. No indication as to the LED brand used, and you have no idea what the output angle is on those. Also, the chances of getting replacement optics for that setup are slim. There are lamps out there that will allow you to do what you want, but I guarantee it will cost you a lot more than what Eco-Lamps is charging. Link to comment
Greenroomson Posted April 24, 2009 Share Posted April 24, 2009 evilc66, Thanks for all the info, I am thinking of jioning the gruops buy. However, I was wondering how many LEDs would be needed to get 200 PAR on a 20 gallon tall tank, (12x24x17") . You input would be much appreciated. Green Link to comment
MGDMIRAGE Posted April 24, 2009 Share Posted April 24, 2009 When the sun goes out, the world will turn to evil. Only when they start making 1 billion watt LEDs Lets hope they aren't solar powered Very nice lights Evil! Link to comment

Green I'm no expert, but 200 par would be simple to achieve. The expensive part would be getting that 200 par spread throughout the tank. Link to comment
evilc66 Posted April 24, 2009 Author Share Posted April 24, 2009 Thats what I was thinking. I don't think these lights would be too practical for that kind of setup. It can be done, and you could get a very Japanese look to the tank, but you could need 6-8 to get decent coverage. Thats $450-$600 if you wanted 12K only. You can build a full high power setup that will give much better coverage and more intensity for less than that. More work though. So Travis, when are you ordering one for your tank? Link to comment
anjay Posted April 25, 2009 Share Posted April 25, 2009 hey evil, what is the difference between the 12k and the 20k? does the 20k have 1 white and 2 blue LED's? or 1 white 1 blue and 1 purple? Link to comment
evilc66 Posted April 25, 2009 Author Share Posted April 25, 2009 12K is 2 white and one royal. 20K is 1 white and 2 royals. Link to comment
milkman Posted April 25, 2009 Share Posted April 25, 2009 12K is 2 white and one royal. 20K is 1 white and 2 royals. Is the par output lower for the 20K due to more royal LED's? Link to comment
evilc66 Posted April 25, 2009 Author Share Posted April 25, 2009 Nope. It's about the same. Link to comment
somechineseguy Posted April 25, 2009 Share Posted April 25, 2009 Evil, I just have a few questions about your new LED light for my 5.5g. I never really understood the PAR system, I basically just had a 250w 20k MH setup and just moved corals around until they grew. What kind of growth should I expect to get from zoas and possibly easy sps(digitata, montis) from probably 2 LED lights? probably the 20k version. Also, what kind of life do these LEDS have? are these the type that still have 70% efficiency after 50000 hours?(ive seen this estimate before) Thanks for your help! Link to comment
evilc66 Posted April 25, 2009 Author Share Posted April 25, 2009 Most anything will grow well under these. Sps will have to be higher in the tank, but montis will grow just fine. Keeping your water parameters in check in a small volume will be the key to success though. These LEDs are top shelf Cree XR-E LEDs. Providing they don't overheat, these should give you a lot of life. I'm not going to guarantee that they will last for 13 years on a 10 hour schedule, but I would expect 4-5 without much trouble.

somechineseguy Posted April 27, 2009 Share Posted April 27, 2009 what type of fixture is everyone planning on putting these in? I know they fit in most standard lamps, but just curious to see what others are doing. Link to comment
anjay Posted April 29, 2009 Share Posted April 29, 2009 i'm going to try to make my own most likely... i cant find any decent looking fixtures anywhere.... Link to comment
adinsxq Posted May 2, 2009 Share Posted May 2, 2009 i'm interested. very cool. but don't think i'll have decided in time for GB Link to comment
anjay Posted May 2, 2009 Share Posted May 2, 2009 i'm interested.very cool. but don't think i'll have decided in time for GB Well, I'll be sure to post lots of pics of my system when i get it up and running! hopefully that can help you decide! Link to comment
