Re: Best IR illuminators
The CIRIS illuminator has an IR LED (note the large lens on the front), while the Luna uses an IR laser diode. One is made in the US and the other in Russia or the former Soviet Union. Here's a brief comparison, the major functional difference is the variation of the IR beam width; the Luna's minimum beam width allows it to throw its smaller spot size a longer distance, while the CIRIS' larger beam size can nearly fill the FOV of the PVS-14 at its maximum:
* Adjustable beam divergence from 2.5 to 30 degrees (the FOV of a PVS-14 is 40 degrees at 1x and 13 degrees at 3x). <span style="color: #FF0000">Luna: 0.1 to 5 degrees.</span>
* Adjustable output power. <span style="color: #FF0000">Luna: 9 brightness settings (not mentioned in specs).</span>
* Can be handheld like a flashlight or rail mounted. <span style="color: #FF0000">Luna: Could be handheld at larger beam widths.</span>
* Eye-safe source (I have grandkids), LED "on" light. <span style="color: #FF0000">Luna: Eye safety not specified, no LED "on" indicator.</span>
* Uses 2x123 batteries, no operating time specified (depends on brightness). <span style="color: #FF0000">Luna: Uses 1x123 battery, 6 hours operating time.</span>
For those outside the US who might be interested in the CIRIS, its ITAR status is under review, "although there are currently export restrictions in place pending a commodity classification."
The CIRIS ($1195) and an accessory Picatinny rail mount ($180) are $1375 shipped in the US.
