Your running 3 in series on two parallel circuits? Have you measured the voltage output of the transformer?

no. Every thing that I read said it didn't matter how my circuits you run as long as you do not go over your MA output. I think the Leds I got run on about 25-30Ma my tranformer can handle up to 600ma.

i think that is really cool looking......very realistic

Krazyplace if you want Macro Algea send me a PM or email I have a ton I am about to dump out of my 29 gallon, probably 4 good size double handfulls.

i cant wait to get some on my tank...snakeman is gonns show me how to wire it all up

Does anyone have a wiring diagram and a list of components?

Snakeman · Post by **Snakeman** » Wed Oct 15, 2003 10:22 pm

Maybe these links will help you, If not I can draw you some diagram of how I made mine. http://ourworld.compuserve.com/homepage ... en/led.htm

If you still have questions give me a Pm.
THey are a lot simpler than they seem to hook up.

Jason, can I get these LEDs at Radio Shack?

Xster · Post by **Xster** » Thu Oct 16, 2003 2:04 am

what is a fair price for these LEDs?

Snakeman · Post by **Snakeman** » Thu Oct 16, 2003 8:04 am

No! Radio Shack Leds suck. Get them off ebay. I payed $15 for 20 blue leds. I got 20 white ones for $10.50 a few days ago. It just depend on how many people bid on them. Do a search for Coldfusionx that is who I got mine from. get the small blue ones not the Jumbo. If you have trouble finding them let me know and I can send you a link.

I just received 50 white LED for $13 shipped. The same company sells the blue ones too. I'll post the email address tonight after I get home. You guys ought to go in together...save some money. Radio shack has a 12.6V 450mA transformer for $7.99. The higher amperages (1A, 2A, 2.5A) are about the same price. They also have a 25.2V version that allows up to 6 LED in series....makes wiring easier.

Voltage is not split when the line is split. What I mean is that if you have a 12.6V source and you have 10 parallel lines, then each line will have 12.6V available. Now you have to subtract "used" voltage if you place the LEDs in series, that is why SnakeMan used 3 LEDs (3.4Vx3=10.2V + resistor).

SnakeMan was 100% right...the limiting factor is the amperage of the transformer. Most LED use between 10-30mA depending on how many volts you run through them. If you assume 30mA then a 450mA transformer will power upto 15 LEDs. A 2A transformer will power about 66 LEDs.

Krazyplace , Young grasshopper has a question. If I use 4 AA battiers to get 6 volts how many MA Is that. Is there a way to see how many MA batteries produce. I want to do some flashlight project.

batteries are different from each other. I have some NIMH rechargeables that are 1800ma's... No clue on alkalines.. prob plenty.

Snakeman · Post by **Snakeman** » Thu Oct 16, 2003 11:43 am

is that 1800ma per battery? That's seems like a lot.

Brandon · Post by **Brandon** » Thu Oct 16, 2003 11:49 am

Should have said MaH I guess.. which is based on discharge rate.. Which theoretically could discharge 1800ma's in an hour or 900 in 2 hours, etc.. I'm sure they are overestimated, but NIMH's still are the bomb.
