Windows 7: Handheld Spotlight

The thing that throws me about your Black & Decker link, is that it specifies a luminous intensity, which is not the same thing as lumens, candlepower, radiance or iluminance. I'm not certain what they are talking about. What is important to me is lumens, because that is the amount of light measured at the target, not that coming out of the light itself. If one makes a supposition that a light specifying lumens is measured only at a 1 foot sphere, then I suppose that you could determine the lumens, but no one uses a light at that short of a distance.

Even if one knows the amount of light that is being produced, that is not all that there is to it, because both the lens and reflector work into the equation in some fashion. I have yet seem any means of computing all of these factors to know exactly what to expect from a beam at any given distance.

I agree Black & Decker's reference to luminous intensity is somewhat confusing.

From what I've read (not much) I think one of the biggest problems for choosing a spotlight is that there is no standard to measuring in either candle power or lumens eg. the distance/method they use.

I think I would go to a local store and ask for some advice, not your local Walmart or your big stores where the service staff wouldn't know jack but somewhere small where the staff would have more of an understanding of what there selling. If your lucky they might even let you test a couple of brands which specifiy in different measurments and allow you to get some clue to the differences and if you buy something they recommended and it doesn't meet your requirements then at least you could take it back easily depending on their return policy.

Good luck with this, going by the forums I linked it sounds very hard to understand what will fulfill your requirments.

Does such places still exist? I can remember stores like that many decades ago, but if there are some still around, they are hiding from me. Maybe because I never go to expensive stores.

That light looks very interesting, but it doesn't give many specs on it, and when I have looked at similar lights before, the price was prohibitive. The fact that they don't publish a price, and require that one request a quote seems to reinforce that likelihood.

I came across one light that I'm thinking about:

WAGAN EL2741 12 VOLT 18 MILLION CANDLE POWER CORDLESS RECHARGEABLE HALOGEN SPOTLIGHT

The price is right, but I can't find any reviews on it. I wanted to call for information on it, but they don't have a toll-free number. Every other light that I have found in it's class had some pretty bad reviews, which made it sound as though that the odds were that the lights would arrive in less than desirable condition.

EDIT: Being a 10 pound light, I guess it's not something that one is just going to snatch and grab very easily. I would need to keep in in position most of the time...at least at night.

EDIT: Ignore me the reviews weren't great and I think you have looked at this one by what you wrote after boohbah's post.

Did you look at this one boohbah linked too? It looks like it might be suitable it has a video review by a customer which gives an idea of the distance and spread of the beam.

It's $38.88 on Amazon if I'm reading right - Amazon.com: Thor Rechargeable Spotlight: Home Improvement

EDIT: The Pelican one linnemeyerhere linked to, I had a quick look on Google and found prices around $600 - $800.

That video was very helpful. It gave a good idea of what brightness to expect, but considering the ranges that he gave at a couple of points, it didn't seem that the beam was very wide...just judging by the number of tree seen. Since that light is ~ 1/3 the power of the lights that I have been focusing on, I would imagine that they have a wider target area, which I would prefer.

Maybe I'm looking at this all wrong, but I want the light for two purposes...first, the obvious of seeing a deterring vandals, but also a second, in that I figure that occasionally I will shine and innocent tenant, and they will complain to the management, which might give them some motivation to fix the street light.

This is just another problem you face, a lot of products don't specifiy there beam angle. I noticed that the expensive Pelican one does and it's only 10 degrees so I wouldn't think that would be very wide.

I hope that I don't regret it, but I went ahead and ordered the WAGAN EL2741. I don't know that it counts for much, but I did send an email to the seller, asking about it's track record, and they claimed that they have not had any problems with it. I also asked about the battery recharge time, and they said that after the intial charge, that it should take ~ 6 hours to recharge. Guess I shall just have to wait and see.
