LED revival - Page 3

Loving LEDs this evening.

After spending much of the day drilling for the the 5g's array, I realized I was going to have more than a few leftover.

So I figured some augmentation of the 2x20w NO's on the 65g right now would be a good thing. Mounted (superglue) 16 of them to a 36" peice of eggcrate, then wired them up. The 2x20w NO's got removed, as they were easily being outdone by the LEDs.

Of course, we'll see how long they last... Tried something 'different' this time. Used my standard 12v 1.2Ah wall wart (actually puts out 14.4v), used 4 LEDs in series, no resistor. I tested a series like this all last week - and it didn't burn any out, strangely even without resistors they're only drawing 34mA. Spec's list a Vmax of 3.6v and max current of 30mA, so they are being overdriven slightly.

I'm thinking I may have to get a few more white and blue LEDs, may just do the 65g up with only LED lighting.

this thread is useless without pics and diagrams and store locations to buy mats

Best place to buy LEDs is by far ebay - you'll pay under 1$ each there (most retailers will charge at least twice that). Personally I like the ones lckwtc is selling, but to each their own.

iagrams - there's a thousand websites explaining wiring LED arrays, just do a google search.

Pics - Might have a few coming later today if I decide to go nuts and light up the 65g totally with LEDs. Not going to post the duct tape and bindertwined version I'm running now

I buy mine from distrubitors, about 1 buck each and no shipping accross the boarder.

That's how I'm wiring up the 5g. Red for positive, black for negative - that blue wire connects an array thats split on either side of the AC300.

That's about as close as you get to a running picture, anything close to overhead results in black with white dots

hmmm. How many times you electrocuted yourself on that thing?

It looks pretty clean and simple - which is good for me if I ever try to attempt it.

Low voltage, low amperage - so I haven't - I could probably lick it and get nothing more than the equivalent of a 9v battery lick.

Figured I'd post pictures while things are pretty clean and easy to see - planning to dip the whole bottom in "liquid electrical tape" before putting it into service.
