lighting idea

[jfoster38122]

was thinking i have a bunch of single leds i got on ebay...red, green, blue, and uv

i have 9 volt battery snaps i got from RS

walgreens has clear or maybe frosted tubes in the candy isle

could i fit all that in a tube use a little oil or what not to lightly seal it all inside the tube with a stopper or cork

punch a hole in the ground and bury the thing as deep as i want and use it for lighting in the cemetary or wherever i wanted?

Hey jfoster could you explain a bit more on what you mean? from what i've read it seems like you want to get a frosted tube fill it with LED's and oil and put it in the ground to light your yard.

hey the oil is just around the rim at the end where you will put a stopper or cork to help create a seal
everything is battery powered so you can put them anywhere
i just thought you could partially bury them if they were too bright or to just get a different look

While it's all technically possible, 9V batt is not a good match for single LED's. You're looking at probably ~3.2V for the green, blue, and UV bulbs, ~2.0 for the red. You've got to burn all that battery power up in a resistor to keep from burning the LED's.

You could probably run series strings of 3 for the G, B, and UV. Those would need 3 x 3.2V or about 9.6V - which would be perfect for the 9V battery alone. The reds, you could probably do a string of 5 or about 10V - and that would work with a 9V batt, too. Or you could step down to 2 AA batteries in parallel and run a single G, B, UV led, Single AA battery for a red LED. Either way, it's all about matching the batt voltage to the LED voltage - otherwise you're just planting a big battery draining heater in the ground.

As far as sealing them, probably what ever you have on hand. Plastic tubes, vials, bottles what ever is easy.
