How hard is it to convert 110v to 3.7v?

[waddup]

i really want to use a couple of p7s as flood lights in my yard.

surely there is a way to do this on standard light fixture/p7 modded bulb?

I have seen 3.6V wall wart power supplies before.
Its just a matter of finding one with sufficient power for your application.

How many emittters and whats your target drive current?

just buy the Philips Xitanium LED driver on the shelf, dont crack your head , it is robust and reliable

The Xitanium is nice. I have the 700mA version driving 4x warm SSC P4. However, since the P7 is parallel only, you should use Cree MC-E wired in series instead.

Hook 34 of them up in series.

think the P7 drop can be driven from like 4 to 8 volts and handle well over an amp but needs to be heat sinked well.

this would be one easy way,
