Hi, it's been a while since I've been on this board, A little history Had trouble with heating issues and corals died, also inherited some sort of poisonous brown algea, so I went fish only for a few years, then one of my pump's had an internal shortage and killed the fish. I was done after...

Have an old t5 coralife 4 bulb 36 inch unit for my 40 gal breeder Its actually a pretty good light, but current set of t5s are getting near 12 months old I have a pretty complete led setup that I bought from rapidled a while ago Would be a good fit for the heatsink to go into body of the unit I...

I think I may have found the perfect non dimmable LED driver for UV LEDs. Since the maximum current rating of most UV LEDs are 700mA. Driving those LEDs at 500mA is near perfect to extend the life of the LEDs. and you would not need to buy a dimmer. Granted most people like to dim, but for...

Hi, I am building a DIY LED light fixture using 8 LED X 10watt each. Below is the spec. Specification of each 10Watts LED 1. Input Voltage: 9-10Volt, 900 MA 2. Luminous flux: LM1200 ~ LM1400 3. Output power: 10W 4. Color temperature: 15,000 K To dissipate heat produced from these, I will be...

Hi All, I have been deliberating which new LED's to get for some time now. My original plan was to used Kessil A360's but they are impossible to get in Malaysia and the cost of shipping them from the US was astronomical! That, couples with the fact that I really enjoy DIY projects (and used to...

In the concept phase of another DIY, need help making the circuit diagram. If anyone knows anything about rectifiers, capacitors, and voltage regulators and has a lot of patience/free time please message me or reply.

Decided to build a LED light for my refugium since I like to tinker with things and just bought new DT lights, but did not go the DIY way. So I ordered up a Mean Well LPC-35-700, 4 CREE XP-E Red LED 1 CREE XT-E Royal Blue LED, and 1 CREE XP-G 5W Neutral White LED, along with some wire, a plug...

It's finally here! The DIY build thread you all have been waiting for.... Give it up for 90ReefZilla's DIY LED Build Thread!! (insert hand held air horns) So, some basic information about me and my tank before we get started. My name is Travis, and I am known as the "Computer/LED/Fish guy"...

I know there are a ton of LED builds out there as resources, and I've looked at a lot of them. I wanted to start a thread of my own so that any questions I have or suggestions you all have are easily accessible. I currently have a dual 150w Coralife metal halide fixture. It's getting some...

Happy Thursday folks. I'm building a LED fixture with Cree LEDs, a heatsink from Heatsinkusa.com and drivers\dimmer kit from Rapidled.com. This is for a 12 gallon nano reef I'm cycling now, it's a Fluval Edge. I have 5x Cree white LEDs, 12x Cree Royal Blue and 2x UV LEDs from RapidLED. If...

Hey guys what sup???? So this will be my first ever DIY project and I was thinking on upgrading my t8 light fixture of a 15 gallon to an led fixture. I will use it as were this is going to be installed.This will be for a 15 gallon and I hope it will not be overpowered for a 15 gallon reef. It...

Hey guys so I was thinking of purchasing this http://www.ebay.com/itm/2x-PCB-Circuit-Board-for-12X-1W-3W-LED-Series-Heat-Sink-Aluminum-Base-Plate-DIY-/230995482392?pt=LH_DefaultDomain_0&hash=item35c8675718 from ebay so I can make light for mu 15 gallon long so there is written that it handles 3w...

Finnished my rapid led diy fixture but kin stuck on wich way to face my cooling fans. Im not sure if I should face them blowing cool air toward the heatsink or pulling hot air away from the heatsink. Just wanna make sure leds are getting cooled properly. Any advise???? Thanks

Hey guys so I'm looking to build my own DIY LED setup for my 48" wide 55 gallon setup. I think I did the math right by taking the footprint of my tank and I found that I should get about 32 CREE LEDs. From this setup I would be able to support SPS growth. However I talked with mike from...

So its been 3 years since i set it up, has gone through 2 moves and countless failures. but its going strong, just got my new LEDS and felt like tanking pics.

LED's are fun to play around with, and they are cooler to have than more normal alternative. Anyway,I've spent about a week researching all about LED lighting, and just about the only information that stays consistent is the spectrum. Different sites rate their products differently (lumens...
