ccampbell Posted January 6, 2012 Share Posted January 6, 2012 Finished a 15 light dimming kit earlier today. No soldering experience and it only took about 4 hours. Hanging it tomorrow and I'll get some pics Link to comment
fast93accord Posted January 7, 2012 Share Posted January 7, 2012 finally figured out how to downsize photos... my 20 long with 24 leds, 12 royal blue, 12 10,000 white, both on 100%. i put each driver on its own timer so morning and night will have an hour of blue... my heatsink goesnt get very hot, i guess due to size... i put the fan on anyway... gonna build a hood and toss the hangers... oh, and im not using the optics... tank looks bad due to gha and diatoms...

Trogdor447 Posted January 7, 2012 Share Posted January 7, 2012 Just ordered 2x 12 LED DIY kits with the meanwell drivers. Making fuge lights out of them.... Each fixture contains- 3x 10000k white 3x 6500k white 3x 4,500k white 2x red Also ordered two extra royal blues for each fixture... RapidLED sells the same drivers and says they can be used for 14 LEDs, so that's what I'm doing. I don't expect the color blending to look nice at all... Just need to grow algae. Did you see my sump build? Link to comment

Felicia Posted January 8, 2012 Share Posted January 8, 2012 Here's my 30 gallon (still working on the upgrade, so there's no water in the tank yet) with the dimmable 36 LED kit 12" above the tank. I used two of the 15.8"x4.7" heatsinks and there are 18 royal blue LEDs, 9 4500k whites, and 9 10000k whites. The drivers and fans are mounted down behind the tank out of sight. Link to comment

Are you worried about water or salt creep getting on the Pot's or drivers? I think it is a slick setup though. Link to comment

I may be wrong but I always thought the fans are supposed to be on the heatsinks to keep the led's cool not the drivers. Link to comment
kgoldy Posted January 8, 2012 Share Posted January 8, 2012 http://www.nano-reef.com/forums/index.php?showtopic=287534 Ah. Guess those 80 degree lenses don't produce much color banding. P.S. All DIY projects belong in your sig. Link to comment
ALexpsycho Posted January 8, 2012 Share Posted January 8, 2012 Is there a way to make a sunrise-sunset effect with the standard drivers? Link to comment
Trogdor447 Posted January 8, 2012 Share Posted January 8, 2012 Is there a way to make a sunrise-sunset effect with the standard drivers? not without creating your own diy project on that, and its totally not worth the time.. and i will get that in my sig sorry Link to comment
iball1804 Posted January 8, 2012 Share Posted January 8, 2012 I may be wrong but I always thought the fans are supposed to be on the heatsinks to keep the led's cool not the drivers. That's what I though. Felicia, place the fans on top the heat sink. That's where it's all the heat is generated! Link to comment
Trogdor447 Posted January 8, 2012 Share Posted January 8, 2012 That's what I though. Felicia, place the fans on top the heat sink. That's where it's all the heat is generated! not fully true.. ray throws in the fans.. honestly in most cases they are not required... Where they really help is when the heat sink is enclosed - the design of a heat sink is to pull heat away and let it cool off with more surface area. Blowing fans over this only increases the air contact with it.. thus making it even cooler. As long as his leds stay a mild warm to touch it should not be within thermal degradation of the leds. and he probably wont need the fans over the drivers either, i just have mine all on the same platform just because its easier for now. Running the drivers @70% or less really causes no thermal build up and it can dissipate the heat properly. Link to comment
Bishop Posted January 8, 2012 Share Posted January 8, 2012 The drivers and fans are mounted down behind the tank out of sight. Fans are for the heatsink. This is like putting the heater outside the water... funny though. Link to comment
kgoldy Posted January 8, 2012 Share Posted January 8, 2012 Am I the only one who bought the non-dimming kits? Link to comment
Trogdor447 Posted January 8, 2012 Share Posted January 8, 2012 Am I the only one who bought the non-dimming kits? lol i think im just to scared.. i dont know if it runs at full 100% all the time or not.. and i dont want that.. lol Link to comment
kgoldy Posted January 8, 2012 Share Posted January 8, 2012 guess if mine is too bright I'll just use diffuser to break it up and tone it down. Link to comment
Felicia Posted January 8, 2012 Share Posted January 8, 2012 I ran the LEDs yesterday and the heatsink isn't heating up much even at full power, so I don't think I need the fans and I don't really want them cluttering up the heatsink anyway. I wasn't going to use them at all, but I noticed the drivers got pretty warm. Since the drivers are down behind the tank and not on the heatsink, I figured I'd run the fans to make sure the drivers stay cool enough. Link to comment
Trogdor447 Posted January 8, 2012 Share Posted January 8, 2012 Fans are for the heatsink. This is like putting the heater outside the water... funny though. Fans are more for enclosures - as fls just said - the heat sink doesnt even get warm.. These leds do not burn like CREE's Link to comment
Felicia Posted January 8, 2012 Share Posted January 8, 2012 Are you worried about water or salt creep getting on the Pot's or drivers? I think it is a slick setup though. The tank is going to have a glass lid, which should block any salt creep from getting to the drivers and potentiometers. Link to comment
fast93accord Posted January 9, 2012 Share Posted January 9, 2012 so i got a project box and some male and female mono stereo connectors and built this enclosure... oh, and 1 of my potientometers works perfect, while the other one makes the driver make noise as is glitchy... enclosure came out perfect... now i just need to make a nice surround for the heatsink to block visually seeing the leds, and mount the fan... i mounted both drivers to a piece of metal that came with the enclosure. looked very professional. i used the qiuck connects for the power cords in case i need to dissassemble. everything else unscrews... another shot Link to comment
cet98 Posted January 9, 2012 Share Posted January 9, 2012 ooooo...a club I can "join"... here's my custom 44 Led AquaStyleOnline DIY retro fixture: here's my build thread: http://www.nano-reef.com/forums/index.php?...288713&st=0 FWIW, this unit is way too strong for my softy tank and is currently running below 40% power so any SPS keepers will more than pleased IMO with it's performance Link to comment

sanchez Posted January 10, 2012 Share Posted January 10, 2012 Put the 48 LED array up over my 24g cube for schnitzengiggle. 'Scuse the wiring mess Drivers are just sitting on a box right now, I have a project box for them but no fan yet, trying to figure out how to power one. There's 2x 120mm computer fans on top of the heatsink, heatsink is cool to the touch running at 60%ish. Link to comment
