I have the normal WF-502B, and its a good product for the price.
Took a while to get to me (from China I think). But overall, a very good buy.
Oh I got it from "Highly Inc" that seller was good. I tried getting it elsewhere and it didn't work out so well.

I'm a fan of Ultrafire / Cree LED products so when I saw they also made infreared LED's, it got my attention. I have two night vision goggles, but when purchasing them years ago, was disappointed at the lack of actual night vision capability these goggles gave out. After doing some research, I learned that it was the infrared source that determined how good your night vision goggles worked, and the factory built in ones they came with frankly were terrible.I took a shot at purchasing this 3w led, already being familiar with the Wf-502b frame using XML-T6 white light led. As soon as it arrived, I put an 18650 battery in and clicked the switch... wow! The whole reflector lit up red. I'm not talking flashlight red, but infrared red, like you see on those clear plastic led's. It was still daytime, so I couldn't test its brightness/capabilities yet.
Night came, and I took out both my night vision goggles and this Ultrafire 502b infrared flashlight. I turned on the night vision, then once focused up high on a tree at the edge of the fence, I clicked this baby up. Bam! Astonished once again. This infrared light lit up the whole tree. I aimed it at the neighbors tree, now about 2 acres away, it had same result. I was seeing further than I have ever seen with stock built-in night vision infrared source.
Because of this new powerful infrared flashlight, I'm able to finally use the night vision goggles for the purpose I originally bought it for. Cree astonishes once again. First with their XML-T6 led's, and now with the IR led's.
I will be taking this out hunting this weekend and using it to scout the field at night without alerting the critters. I rate this one of my top 3 purchases I have ever made on Amazon and am more than please with the product.
I will try to take some pictures when I come back from being out in the field. It's going to be difficult because cameras pick up infrared light as regular light on screen.
Note to other customers:
The customer, samuel clements who also purchased this product must either have faulty night vision goggles of received a faulty version of it from the seller. The led fits the description of 850nm, which is infrared wavelength. Blacklight wavelength is 390-410nm. This baby glows faint red to the naked eye. The only time it glows purple is when using a camera phone to look at the led. Using proper night vision, this baby shines like a regular flashlight in the view, without the actual white light on the outside.
