DIY Moonlight

Well I decided to make my own moonlight since it was a little cheaper and I could modify it how ever I wanted to. This is my fist DIY so if I leave some stuff off just post and I'll try to respond asap

DO THIS AT YOUR OWN RISK YOUR! YOUR MESSING W ELECTRICAL STUFF THAT CAN DANGEROUS AND CAN CAUSE A FIRE IF NOT CONNECTED RIGHT

with that said let's get started

Cost
right about 8-10 dollars total

Materials need it

LED's
Resistors
Switch
Soldering Gun
Wire
Drill
some sort of metal
Old Power supply like from a phone charger or something similar

Ok well the LED's that I use are 4v 25mA 35degree and there 3, power it's 9V so the resistors that I will be using for this is 3 200ohms

First thing you wan to do is solder the resistor to the negative side of the LED's you wan to do this to all 3 LED's


Next connect the LED's w the wire positive to positive and negative to negative like soo


next drill a hole in the back of the light cover to put the switch in trough there next connect the positive wire of your power supply to one of the outlets from the switch after that connect the other outlet to the positive wire of the LED's. Then connect the negative wire of your power supply to the LED's

Next you want to build your brackets to put the LED's in there. Here is a pic of my brackets you can do do them how ever you want



then drill two holes one is for the LED and the other one for the screw to tighten down the bracket



after that screw the bracket w the LED on to the light cover like so (you might have to put some hot clue or silicone to hold the LED in place luckily I made my hole pretty good to were I could wedge the LED in w out having to use anything)




do the same for the other side
I kinda left the LED in the middle just hanging because I couldn't find anything to mount the bracket to soo I just left it hanging

dont forget to put black tape to your expose wire.

Also tape your wires to the edge of the light cover so you don't burn them w your regular light and this is sort of what your moonlight should look like



and here is how it looks like once its all done




it's kinda getto but it's cheap and it works soo I like it lol

I would recommend getting some wider angle LED's

You can sand the top of the LED to make it wider. You don't want to do it flat, make some angles, like a prism. Quick and easy way to get some width, though usually not as good as an LED made for that.

i made something very similar, looks great! i would definately lightly sand them with a fine grit sand paper. like "talontsiawd" said dont sand it flat, try to keep the lense the shape it is (rounded)...if it is flat, try to round it out a bit. you dont really want to grind on it though, like i said, "lightly sand". your outcome should look almost like frosted glass. this should diffuse your light better great job
