Thanks Stephen, I'll try that

I haven't officially started a real feeding regiment yet, but the couple of times I did try this food out I had trouble with it...that is, once it's defrosted and I try to put it in the tank, it pretty much disintegrates immediately. There's not any real form to it, so a lot of it just doesn't get eaten. I'll start the regiment tonight (rabbitfish now showing ich spots).

bump!

Do other LEDs light up when you plug them into number 3? That would be a good way to test each led. Use conductivity mode to check for a short like I suggested before, and check conductivity between the driver positive or negative and the first and/or last led

Planaria?

Sounds like he won the RapidLED retrofit kit, and is trying to put it into a Marineland Non-LED housing.

For sale...Hagen 48" Dual T5HO Light. I bought it second hand from a member here, so I don't know the age, but it's in good shape and hasn't had any problems. The bulbs are one of each: 12K, 10K, Actinic Blue The 12K is about 3 months old, I don't know the age of the other bulbs. Price is $60...I live in Leander, and work in North Austin, so I can meet up on the north side if need be. Thanks! Kevin

I'd start with checking for shorts. Set you multimeter to conductivity, then put one probe on whatever the LEDs are mounted to, and the other probe on a positive and negative solder pad of each LED. If it beeps, you have conductivity which is bad, you'll have to figure out how and why the connection is being made from the LED to the mounting surface. Next I'd set the multimeter to check voltage @ 20amps. Put the probes on the positive and negative leads coming out of the driver. Obviously the LED string needs to be powered. Is it giving you voltage? Depending on the driver, it should be anywhere between 12 and 24v. If you don't get voltage, you know that the problem lies with the driver or somewhere ahead of it. If the driver is putting out voltage, put one probe on the positive side of your first LED, and the other probe on the negative side of your last LED. If this is good, the the connection between your driver and LEDs is good. Next, use the multimeter in conductivity mode again, and this time test the connection from one LED to the next starting with your first one. If the connection from LED 1 to LED 2 goes positive then negative, our the probes on the positive of #1 and the other probe on the negative of #2. This will check if you have a good connection between the two. Test all the way down the string like this. If all this seems ok, then use the Diode setting on the multimeter and check each LED. The diode symbol looks like a sideways triangle with a line next to it. Sorry if my explanation seems elementary, I don't know how versed you are in this stuff. kevin

Yeah, I sent you a pm...let me know if you're interested

Fixed it...a couple of solder joints were too big and touched the side of the LED pcb, causing a short

Looks like it's a shorting problem...I'm trying to track it down, but I've got continuity between the aluminum and a couple of led positive pads. the search continues...

So I got my first string wired up tonight, 14 LEDs in the blue , royal blue, and violet varieties. The product page for the meanwell driver I'm using says it powers 8-14 LEDs. My string has 14 LEDs on it currently. I tuned the output of the meanwell to 700ma. I have it connected to my Typhon LED controller that uses PWM dimming, it is set at 100%. The problem is that I can't get ALL the LEDs in this string to light up. When I plug it in, I get: 1-8 lit 9, 10, 11, 12, 13 unlit 14 lit I've tested all LEDs and they are good. I'm at a loss...what could the problem be? Kevin

I will be selling my Hagen 48" Dual T5 fixture in about 2 weeks. PM me if interested

Sending pm

Yes! Last names in Cooper Black type would be pimpin

Sorry, I'll have to disagree, I wouldn't want it for myself. I think it would probably increase costs as well

Ha!

Here's my entry for the Port Aransas trip. Aaaarrrrr matey
