What Are the Best Types of Lamps for a Compact Solar Simulator Setup?

[lifesigns]

I'm doing an experiment on Solid-State Greenhouse effects. For my setup, ideally, I require a solar simulator lamp capable of fitting inside a 1" diameter (~2.5 cm) quartz tube. The two types best capable of simulating the solar spectrum seem to be:

1. Quartz Tungsten Halogen lamps - A great blackbody radiation source, but most seem to operate at a temperature ~3300 K (compared to the solar spectrum's 5780 K), essentially these lamps give off a disproportional amount of IR compared to the visual parts of the spectrum.

2. Short-arc Xenon lamp - Most often seem to come mounted in bulky apparatuses and requires heavy filtering to achieve a reasonably close solar spectrum (hard filters could be tough to fit in a 1" tube).

Recommendations?

You didn't tell us how much power or how closely you need to match the spectrum.

LED grow lights may fit your needs. LEDs have low power consumption, they are small, and the grow lights deliberately try to match the solar spectrum.
