Looks like you're a little EXCITED about this group buy!

Can you also order the matching resistors from this site? Also, do they have 100 degree LEDs instead of these 30 degree ones? Might create less spotlighting.

 

[Daragon]

You can buy the resisitors at Radio Shack for .99

 

[clamm]

radio shack for resistors, dont have them...i plan to use pots so that I can very the resistance and increase and decrease the intensity to what I like w/o overdriving the bulb...remember they recommend 3.3V to drive the bulb. Also, recommend getting a few extra bulbs because you can damage by improper soldering.

and yes, im excited about this...get to finally use my degree with this hobby to save a little cash, and it will be fun.

 

[clamm]

30 degree are all i have seen...Im just going to use more bulbs. Im going to use 12-15 bulbs...

 

[NateHanson]

Cool Casey. thanks for the info. If I can't get them from 3Mrhythm I'll probably get in on this.

 

[clamm]

Ok, no problem...wiring them is very easy, I may do a DIY thread and show what differnet resistors will do...

 

[NateHanson]

I think a DIY thread would be great.

Would you consider...

...having a 'workshop' at someone's house (it could be mine) when all the pieces parts come in so we could all wire them together. That way, those of us that aren't as knowledgeable about electricity could get a little help.

We did something like this awhile back when we put together some cheap float switches. The way it worked was someone hosted the 'party'. People signed up and different people picked up different parts (enough to cover everyone attending). We assembled them at the host's house, paid for a pkg of parts and went home an hour or so later with 2 float switches.

Just a thought,

[clamm]

i am open to that...

 

[Armando]

what is the suggested power/transformer/etc for this?

 

[clamm]

Transformer

ANY GENERIC TRANSFORMER. 1-6V DC OUTPUT 120AC INPUT. AT LEAST 300mA....600-1200mA idealy. you can also go 1-9V if you have to...just might have to just different resistors. If you goto the link provided you will see what he used. If in doubt, I would just duplicate his setup.

 

[clamm]

i would go with a 9v 300mA one, they are probably about the cheapest and the most easily to come by. You really dont need a 600mA or a 1200mA unless you plan to experiment, as do i with different numbers of them and different series/parallel circuit combo's.

 

[Armando]

the guy used 5 bulbs in his 4 ft tank. Is this a good number or overkill? What do you guys think?

PS: I like KAS idea!

 

[clamm]

im using 10 on a 75 gallon because you only get a 30 degree angle of coverage, I don't want as many dark spots... but with 5 you will be fine but you wont have 100% coverage unless you are very good and accurate with your spacing.

 

[clamm]

*Caution* Just a warning. I have seen people mount these on reflectors. You have to be very carefull when doing this to make sure that the leads dont short out if your reflector is metal. If mounting to a reflector I recommend only allowing the bulb to stick out through the hole because if the leads do also you can short them out. I am also adding a 3amp fb fuse in my ciruit for extra protection. these shouldn't draw that much at all...you can add them up roughly, what was it 20mA per bulb. depending on how many you use you might even use a 1amp fuse. basically you would just place the fuse in series with the anode of the 1st led. That way if the fuse opens you have no circuit, and no current going though it.

 

[clamm]

3m has similar leds for like .75 each so im going get them from him unless he runs out.

 

[Matt L.]

I'd be interested in this, as those moon lights are so darn expensive, but I'm not confident about making something water resistant and wiring it up myself. Could some of you electrically inclined people post a wiring diagram. Then I'd certainly be interested in buying some, if the group buy is still open,

[clamm]

It is. basically you have your supply with a positive and negative comming out of it. you take the negitive and connect to the anode take that wire you just connected to the anode and run it to the next led anode. so you are running them in parallel. you keep doing that till all the anodes are tied together. then you have to do the cathode portion...only this time you wire a resistor in line with each cathode. So you would come out of the + end of the supply and go into a resistor, the resistors other end would then goto the cathode of the 1st led. You would then run a wire from the same point cathode of led 1 to another resistor attached to cathode of led 2...you would continue to do this till everything is done, if you want I can help you.

it looks like clamm is no longer doing the group buy. Matt since you're volunteered, you're the new organizer
