Can sometimes get halogen outdoor floodlights on special $5-10.
Got two that way, room enough for a Pi and a bunch of 1Amp IR LEDS.
I use this to inject power over the Ethernet cable

The 12-24V goes to a 12v USB cigarette plug $2 on special, some can handle up to 24Vdc.
Grab a RJ45 crimper, lots of plugs and a roll of cable, next thing your house and garden is wired up.
I use one of these to driver the LEDS, dial up the power I need.

Not sure who makes 940nm 1W+leds, alternative is lots and lots of 5mm 940nm leds.
Checked Osram, they have some.

Still trying to figure out how to strobe/GPIO control my 850nm leds, might have to make up a mosfet pcb on vero, work in progress.
