Rayovac BRSLEDPEN-B Brilliant Solutions LED Pen Light (Colors may Vary) Reviews
I have tested several LED flashlights before, including the MAGLITE 2-AA Mini LED, Rayovac BRSLED2AA-B Bright Solutions, Energizer Aluminum 2xAAA Pen light (PLED23AE), and Dorcy 41-1218 2AAA Pen Light. They all share a common problem: the LED brightness is strongly dependent on the battery voltage. Full brightness is only achieved when using a fresh set of alkaline cells. As the battery voltage drops, brightness also falls rapidly. This is very disappointing because I prefer to use rechargeable NiMH cells instead of disposable alkaline cells, but not if I can only get 50% brightness.br /br /This Rayovac BRSLEDPEN-B LED Pen Light is cheaper and smaller than all the other LED flashlights above. It uses only one AAA cell instead of two. Yet surprisingly, it gives out the same brightness whether I'm using alkaline or NiMH cell. I measured its input power and found that it consumes nearly the same power as the battery voltage drops from 1.8V down to 1.1V (see my Customer Image for charts).br /br /When powered by a NiMH AAA cell (1.25V), this pen light consumes about 120mA. I have tested the run time using an 800mAh cell. The light output is consistent for the first 6 hours. Only after 6.5 hours the light becomes noticeably dimmer. This run time is very reasonable for a 1xAAA pen light. Note that other LED flashlights may claim some outrageous run time such as '100 hours', but that number is misleading because the light becomes barely visible towards the end.br /br /This LED pen light uses a magnifying lens to concentrate the beam. The circular bright spot it creates is well-defined, but has a 'halo' effect (look at my Customer Image and you'll see what I mean). This is a common problem with most flashlights using the same design.br /br /One 'shortcoming' of this Rayovoc pen light is that: since it is so tiny, it can be easily misplaced. At the present price (around ), I intend to pick up another one or two just in case. I will do it when I need to stuff my Amazon shopping cart to - to qualify for super saver shipping. That way, I can tell myself that the light is FREE!br /br /[Update on June 23, 2010]br /I received my second Rayovac pen light and its case is blue (the old one is grey as pictured). The light beam from the new one is whiter and brighter. So I guess there is an element of luck involved.

It stoped working. - M. Sugimoto -
I loved this one while it was working. It requires only one battery instead of two as other lights. This makes much lighter light and comfortable having in knit shirt pocket. The first battery was getting dim so I replaced it with fresh battery. But, it didn't light up??? Why?? It's not like I put battery in wrong way. I don't think I will buy another one.
