I paid 69$ for my NiteCore CI6 Chameleon flashlight makes a huge difference with my Gen 2 Nod plus it has white light, red, green, blue, SOS and strobe features you should check it out!

Thanks xjronx, I'm going to order an ultrafire 502b and do a side by side comparison when I get it. the 502b has been around a long time, and was a go to host for lots of custom light and laser builds. the hot set up for the 502b is one of ahorton's drop in IR pills with a spacer/non reflector and an aspheric lens. he sells or sold conplete units too. they arent too shabby, but cost about as much (pre made) as the pro tac. the new DIY hotness is the t-20 ir build. larger aspheric and twist head for flood to zoom focus.

Quote Historyultrafire 501b and 502b are essentially the same housing, just a little different looking. That 3w ir led is pretty bright, its actually 3 led's , very small next to one another, so the output is very floody and hard to focus into a tight beam in any light. I think that drop in runs about $11 on some websites with cr123s when the battery voltage drops a little the led goes into blink mode. with those rechargeables you should get better runtime.

Posted Via AR15.Com Mobile Since the 501b is only 1 LED at the same wattage, is it a tighter beam and about the same brightness? If so, it would definitely be a better option since it's also $10 cheaper. |

even 2 501's or 502's can have sublte differences.
the difference in the throw and spill can be just the reflector, I see one is smooth and one is orange peel. sometimes the reflector screws onto the pill and shifts the heatsink breaking the wores or shorting. sometimes the large spring on the back needs tweaking to make contact. and sometimes you just have a bad drop in. one of about every 10 I buy is defective somehow, but the rest work Posted Via AR15.Com Mobile |

Tightened down the UF1000 lens cap and it fired right up. So the UF1000 LED/reflector/"bulb" delivered about 4 minutes of run time before burn out.  |

hard to say what the problem was but it could be an issue with those rechargeable batteries and the the voltage the led was meant to run at. just because the seller supplied rechargeables, doesnt mean that drop in was meant to run at that voltage. when too much voltage is applied, most drivers dissipate the extra as heat, and that usually fries the driver ot led. its a good host, so get another drop in, just read the specs and make sure its spec'd for the voltage from that battery.

Nitecore has a couple lights with vis and IR amd they run under $100 iirc. Posted Via AR15.Com Mobile |

Quote HistoryQuoted: Let's start with the photos: Side view http://www.ar15.com/media/viewFile.html?i=70298 And top view (the XT8 LED does not show up in this picture - it was about 1/3 the size of the UF1000's LED) http://www.ar15.com/media/viewFile.html?i=70299 The Hwa0wys Ultrafire 1000 included two 18650 batteries and a charger for a total of $ 15 from Amazon. Side by side the two units are more like brothers than identical twins. There is the same design to each but the head, body and tail cap of the UF 1000 were all slightly shorter than the XT8's and the wall thickness was less as well. The XT8 bulb/reflector and tail cap were of higher quality than the UF 1000. I think the pictures illustrate my point. I put the two beans up side by side on the wall. The UF 1000's spot was definitely a truer "white" color but it covered an area roughly 250% larger and had a more diffuse & larger flood effect beyond the spot. The XT8's spot was slightly "yellow" but was a very tight spot with a sharply defined edge with the flood area being brighter and more tight around the spot than the UF 1000. My intent was to take a picture of the beams side by side ... but before I could the UF1000 blinked once, went out and has refused to light back up since then. Any suggestions on resurrecting the UF1000 or shall I just contact Amazon and express my displeasure with their "Prime qualifying" product?

Any suggestions on resurrecting the UF1000 or shall I just contact Amazon and express my displeasure with their "Prime qualifying" product? The 501b IR bulb ($ 15 on Amazon) finally showed up and I've used a sealed basement room for a quick comparison with the XT8 IR bulb. As mentioned above the XT8 IR bulb puts out a crisp, tight circular spot beam of 12 - 15 degrees from its three LED's. The 501b IR beam is almost as bright but has an irregular distortion along one side of the spot - there is nothing visible on the aspheric plastic drop over the three LED's and the spot is more on the order of 20 - 22 degrees across with some spillover. After it get's dark, I'll check them both outside against one another and update this post ... if there is anything else to add. I am considering buying another XT8 IR bulb and placing that in the Ultrafire 1000 body. That would provide the somewhat better IR beam (for $ 30 from ExtremeBeam) paired with a $ 15 flashlight body from Amazon. The "hybrid" would have a total cost of $ 45, provide theoretically the same performance and save $ 31 compared to my original post on this thread.  |

try, carefully, to adjust the reflector position by screwing it in and out a little. you might find a better sweet spot. they are interchangeable too, you can try swapping reflectors.
you can find an aspheric for the 501 on several domestic and foreign websites. I think mine came from deal extreme and cost $3. the key though is making a spacer for it, or buying ahorton's. Posted Via AR15.Com Mobile |

Outdoors the difference between the XT8 and 501b IR LED units is even more pronounced. The 501b loses a good deal of its "spot" characteristics after 50 yards. It isn't a Torch Pro by any means but then again the Ultrafire 1000 flashlight body with the XT8 IR LED "bulb" will cost a lot less money. |

Is 850nm the best wavelength led for IR detection devices Gen1 and up? I see 940nm offered but from what I can tell they are best for IR camcorders. Anywhere to get more information on what works best with what?

The 940 nm source is supposed to be invisible to the naked eye unlike the dull red glow of the 850 nm LED's. Unless you are hunting those two gazelles with NVG, you should be fine with an 850 nm unit.  |

You want to drive the Osram led at 1050ma or 1.05 amps. Directly driven at that amperage the light will be to bright for 3rd gen intensifier tubes. I used a single mode 1.05 amp driver and removed 2 out of 3 of the 7135 chips reducing the amperage to 0.3 amps +/- and I was still getting burn under 50 yards focused to a spot. I didn't play with it much at full power as I wanted something I could actually use but I was lighting up trees over 1/2 mile away. I ended up buying a custom programed driver and set it for 2 modes. Low and lower.
I posted a shopping list a month or two ago to build one of these. You can do it for less than $40. It's not kosher here to repeatedly plug non paying venders so I won't. I will say about the link posted above for the emitters, the owner is gtg and will build one for you if you ask. If anyone is adventurous and wants to build one and needs some advice send me a pm. I would be glad to help. All you have to do is some basic soldering. |
