You could get some superbright LEDs that match the wavelengths too. Then create an array of standard 5mm LEDs (add a few resistors) and power that. Not as intense light but would still do the job.
You'd need to put them close to the plant.
A guy on the chilli forum has four 130,000mcd blue set in an old espresso bean can to make a solarium for a signal chilli.. that chilli is now really doing well and fruiting once out of the blue (needs some red to trigger flowering/fruiting).
Am using a set of these over a planted fishtank, they are rather good. The good thing being that they don't throw out any heat and are easyer on the power usage. Not as good light outup as a set of MH but nice all the same.

I'm using a 400W Euro Grow light combo which is a little confusing but only one bulb is used at one time but you get separate MH and HPS bulbs in the pack. There is, of course, the dual spectrum bulb version (and you can buy other bulbs too as needed). Just to explain the acronyms to anyone reading:
MH = Metal Halide which produces a blueish cold light that causes the plants to grow vegetation.
HPS = High Pressure Sodium which produces a orange tinged light that is meant to help promote fruiting.
The dual spectrum is basically MH and HPS in one bulb.
The reflector is ok but a little flimsy (does the job - don't get me wrong).
Metal Halides which produces a blueish light come in different shades from orange to blue. The more blue the light the higher the color temperature, 20000k is very blue white --------> 3000k is a very orange white. So you could drop the HPS unit by having a few MH blubs with differing color temperatures. Do you blubs have a UV filter, if not you should use a UV filter glass?

How long to the chilli plants live?
