They don't seem to hold the advertised power, and except on low, I don't trust the reliability with the excessive heat generated. <br /><br />For testing the higher settings, I'd RX dropping the flashlight in ice-water after turning it on "HI". <br /><br />I usually have the light in default mode with the stock NiMh battery, as that fills in ahead of my MagicShine bike light without diverting my focus, so not sure why I'd want to risk damaging the light for brightness I don't need. <br /><br />In very cold conditions, the light might be OK using the 10440s, like riding in winter, but also not when you want to risk ruining the light. <br /><br />I think the best decision is to just buy a single 18660 Fenix flashlight, and use it at spec.Grey Beardhttps://www.blogger.com/profile/02238917041257429804noreply@blogger.comtag:blogger.com,1999:blog-4048496041370417301.post-14885618447543949262012-06-12T06:53:05.519-07:002012-06-12T06:53:05.519-07:00I recently bought an LD01 and a couple of 10440...I recently bought an LD01 and a couple of 10440's for it, as I'd heard how bright it could be. I am delighted with this light for general use, and amazed at how bright it is using the 3.7V cells. I only run it for a few seconds at a time on the higher 10440 outputs, as it does get hot very quickly. <br /><br />Have you noticed any problems with your 10440 cells after using them in the LD01? Mine have gotten squished down, so the pole is almost flat with the top, instead of sticking up like it did when new. I expect this is due to the fact that the cell is slightly longer, and twisting the LD01 down to turn it on must be pushing the top down more than it would an alkaline cell.<br /><br />I'm concerned about the health of my 10440 cells, since it would seem that compressing them isn't doing anything good for their structural integrity.Anonymoushttps://www.blogger.com/profile/03451516553981756702noreply@blogger.com
