How can you make an LED light run that is as bright as 70 watt buld on 110v AC?
I want to build a light like the one below because I don’t want pay $35 for a pre-made one. I know it can be done because I own a night light that is just a blue LED. I figured $35 for what amounts to a cluster LED’s, a resister, a compositor, and a base is a bit excessive when you figure they’re built in bulk.
When I searched on Google all I could find was plans for battery powered lights.

I am working on this very same problem now for the same reason you are.
You need the brightest LEDs you can find, but you have to take into account *both* the mcd (millicandela) rating, and the angle of light projection. The two combined determine lumens, and it’s the lumens rating of a bulb that you want to aspire to (but good luck, incandescents are bright). There is a calculator on the Web for mcd+angle -> lumens.
The brightest LED now made is supposedly made by Cree. You can get a free sample but there is a delay in getting it.
Anyway I suggest using a spare AC adapter for AC->DC conversion. Put the LEDs in parallel of course and calculate the proper resistor (need a high wattage one!) using Ohm’s law.
