    UV model needed for scorpion hunting

    Would they run away if you light them up with philips luxeon UV LHUV-0390-0450 (390-395nm, 3.1W, Peak Wall-Plug Efficiency 32%)? What about LHUV-0380-0200 (380-385nm, 3.2W, Peak Wall-Plug Efficiency 15%)? or LEDENGIN - LZ1-00U600 - LED 5W 365NM?

    Most Powerful & Uniform IR illumination under 4lbs: HID w/ 850nm filter vs multi-LEDs

    Re: Most Powerful & Uniform IR illumination under 4lbs: HID w/ 850nm filter vs multi- I think Axton also uses Osram Dragon 850nm leds, but they claim a much better range. You have the 10-20˚ or a wider model? I believe these are 3W, have you considered swapping them for Oslon SFH 4715S ?

    Most Powerful & Uniform IR illumination under 4lbs: HID w/ 850nm filter vs multi-LEDs

    Re: Most Powerful & Uniform IR illumination under 4lbs: HID w/ 850nm filter vs multi- I guess you mean in spot focus. Also the case for flood focus?

    Most Powerful & Uniform IR illumination under 4lbs: HID w/ 850nm filter vs multi-LEDs

    Re: Most Powerful & Uniform IR illumination under 4lbs: HID w/ 850nm filter vs multi- I was searching xenon short arc portable lights that 1) have variable focus ranging at least 3° to 9° 2) no distortion or darkened areas within the beam pattern (i.e. no “black hole”) over the entire range...

    Most Powerful & Uniform IR illumination under 4lbs: HID w/ 850nm filter vs multi-LEDs

    Most Powerful & Uniform IR illumination under 4lbs: HID w/ 850nm filter vs multi-LEDs Edit: I should have said under 7lbs including batteries, instead of under 4lbs without batteries. Should have batteries for at least an hour at full intensity. Edit 2: This is about flood not spot. Say 10˚. I...

    Sold/Expired Ahorton's sales (Lenses, headlamps ...)

    So if you get a V4 you can then carry others LEDs with you in the field and when needed with a few minutes of work swap between white, IR and green? Would you need special tools to do that or just a good SOG/Leatherman multitool? Is there many headlamps that offer that versatility? FWIW I'm...

    Oslon InfraRed light with 3inch aspheric

    That bouncing back seems like a significant problem. I guess there is no way around it except distance the lighting source from the camera locations? Or maybe get a IR-corrected objective lens. Have you tried some sort of multi-LED panel (like the 10° 240'/73m 10oz IP67 (12-36)VDC 8W Axton i...

    Green & IR LED for Zebralight, ArmyTek, Fenix Headlamps, other (like NightMaster 800)

    Green & IR LED for Zebralight, ArmyTek, Fenix Headlamps, other (like NightMaster 800) I'm looking at the Nightmaster 800 and really like the concept. In particular having different LEDs stored in a flashlight neck, ready to go. Is there a headlamp product that offers that? Or can we buy spare...

    NightMaster 800 and XSearcher: white XR-E, white XM-L, green & IR beam angle ranges

    Re: NightMaster 800 and XSearcher: white XR-E, white XM-L, green & IR beam angle rang Also is one of the 2 white LED (XM-L or XR-E) a natural white (about 4000K)?

    NightMaster 800 and XSearcher: white XR-E, white XM-L, green & IR beam angle ranges

    NightMaster 800 and XSearcher: white XR-E, white XM-L, green & IR beam angle ranges I'd like to know the approximate beam angle range for the various options. That is, I'd like to know the hotspot angle for widest flood and for narrowest spot as well as the total angle for widest flood and...

    Oslon InfraRed light with 3inch aspheric

    In the pics that you don't see a IR hotspot (smaller circle of IR illumination) is it because you're using the night vision without the IR flashlight, or because you zoomed out the flashlight? Do you know roughly what it would look like with the flashlight but without the night vision (just with...

    Infrared Filter Sheets on Fenix HP30 or separate IR illuminator

    After more reading I realized that a IR filter would probably not work on a LED flashligt. I guess I'll need to mod the lamps with IR LED and green LED. I'll read a bit more and make a new post, that will hopefully make more sense

    Fenix HP30 lighting natural enough to use for photography & filmmaking?

    and if not, can one change the LED to get the colors to come out as they would with daylight? or which compact light/headlamp would give the colors more justice?

    Infrared Filter Sheets on Fenix HP30 or separate IR illuminator

    I'm looking to buy a Fenix, zebralight or armytek light. I would also like to have some powerful IR illumination, not to use at the same time. Option 1 add infrared filters to the white light. Would that reduce significantly the lumen and range of the illumination? which filter? filter sheets...
