Good idea using the ski pole LED Thrift!:thumbsup: May have to try it sometime, though I personally don't have a problem with just loosening the tailcap a tiny bit.
I know only owners of both lights are supposed to chime in, but I couldn't help myself.
I don't have the LD10, but my friend has the LD20. The LD20 is a good tough light that has served a lot of people well, but I do not like the design, the beam, or how you have to cycle through all the modes to get to your desired setting. I'm not saying that it isn't a good tough light, it's just my oppinion that the SC51 is designed quite a bit better.
At first I didn't like the look of the SC51, which is why I waited to so long to get one, but since I got mine about 8 months ago, it has become the light that I use more than twice as much as all my other lights. It is amazingly bright! There are a number of 2 AA lights that don't make 200 lumens. Last I checked the 2 AA LD20 was one of them.
I think the quality of the SC51, the ease of use, the amazing output, and how much fun it is to play with make the SC51 a clear winner. :twothumbs
But, if you feel differently, no worries! Both are very good lights!
