Is this a long range black light? Will it be powerful enough to test jadeite to ensure that is it real and not a reproduction; i.e., will it florece?

No. I bought it for similar uses and it is basically worthless. If you want something for minerals you need a light that will emit A,B, and C ranges. I haven't found any that work for under $200.

Sorry to say that this is not a long range and do not think it would be powerful enough to test jadeite. I specifically used it for when my furbaby was sick and wanted to be sure I got all the "spottings" cleaned. As far as that went, it does what I want it to do. Range wise I would say at most 5-7 feet! Consider the price and that pretty well sums it up! Hope this helped.

Nope it was ultra weak! Try another brand. I found a dye leak tester at a local auto store for about 20 that worked well for that

its not that strong of a light source. i order a different more powerful set to go along with it.

Susanna, all the answers below are addressing you testing the light during the daytime. If so, they are correct. One item that you may want to consider is how you have the light powered. This is a powerful light, and at night time I can stand 300' away from my house and see it clearly. So, if possible make sure you are using the correct power source that came with the light, and also, if you have it in a power strip it does not always receive the power it needs. Try plugging it in to a single outlet, and you will probably solve the problemm. Good luck. Dan

It does pick up any light that is out there but at night, without any light source, it is hard to see. Not a big deal IMO since you you should not shoot at something if you cant see it....the main thing is that it actually works at 100 yards and is fairly accurate. I was surprised.

I was skeptical myself. But for me, it's a god send!!! I Love it. And I only paid about 50 for mine. Be sure to get minimum 10,000 Lux!! Hope this helps!!

I bought this and it died within 3 days so I don't know. I had to return it. While I had it I found that the light was not bright enough and also that you cannot adjust the angle.

I apologize for not getting back to you sooner. I rarely ever check my email. I bought this light as a replacement bulb for (a very old) outdoor fixture located above my car. It is strong enough to light up my side of the street (as well as a few other houses). As far as reptile care, I have no idea. Sorry, I was unable to answer your question. Best of luck finding your answer.

It is a great light It does have some long range viewing but if you dont aim it right you do get a hot spot. Overall i would buy this light no questions asked.

I have since purchased a new light from my first review. I would not recommend this light. The light will not stay charged longer than 45mins. For the first 20mins. The light works well then slowly light grows dim. If you are looking for a inexpressive light that works well; I would recommend you continue to look.

It's very bright for such a small light. I would say the beam shines 150 yds before faltering off. If you really need a tight compact beam for ultra long distance, this wouldn't be a good fit.I'm guessing this has a 20' diameter spot at 100yrs. Also, I'm very surprised at the operating time before charges. It's very good. Build quality is excellent, marine quality. I was tired of buying cheap flashlights that only last a few years. This will last a few decades.

Probably...I can't really say how far the throw is, but there is a very bright center spot. I would say that for its overall lumens, it probably will spot things farther than other lights of similar power.

I don't know about the Cree but if # of lumens means anything, I would assume the Cree would be better. I am very satisfied with my Cygolite.

I'd say those infrared lights were not designed for such a long distance - especially if you are talking about an exterior garden or an open field. Half that distance (15-20 feet) is more likely.

The info. I got was 500. I have no way of testing it. At 500 or 600 its still super bright. I saw a test where it beat a 800 lumen light.

Send it back to amazon for a refund or exchange it for another one and hope it comes from a different seller. There are alot of fakes from all these cheap LED flashlight's that are identical in look's but not in quality. Good Luck

Radiates about three foot radius, distance will depend on the light requirements of the plant. LED puts out minimal heat, so it should not scortch the plant. Have one light on 12 hr timer to supplement the Alaskan winter "daylight", So far so good, because my orchids are spiking blooms and orange tree has not dropped it's fruit or leaves. Good luck

I don't know the technical answer. I'd suggest you Google it and check the Ottlite Website. I'm happy with its clear, crisp light.
