The CIRLS Kit is available in 5 and 10 piece versions and offers visible and IR (steady or strobe) lighting to mark LZ, HLZ and DZs.
Powered by your choice of CR123 or AA batteries! In steady on mode you’re looking at 40 hours and the strobe mode, expect a light to run for about 200 hours.
The kit also come with tent stakes to hold the lights down.
One other cool feature is that there is a photo electric eye in the light that detects the ambient light level and automatically adjusts the light’s output.
