Object/Subject Review: Lumapower EDC LM21 (In Progress)
Review in Progress...
Lumapower has been in the illumination business for about 10 years now, and has been making LED flashlights since 2006. They've got several lights that they're well known for, but their new EDC series will be my first experience with Lumapower. So far the new EDC series consists of the LM21 (single AAA or 10440 li-ion), LM31 (single AA or 14500 li-ion), LM32 (double AA), and LM33 (single CR123 or 16340 li-ion). They've also announced that the series will include the LM22 and LM36. They've confirmed that the LM36 will take a single 18650 li-ion, and my guess is the LM22 will take two AAA. Each light in this series has the same look, with knurling on each end and a smooth portion in the middle where the brand and model number are printed. They have matching anodizing and green tail switch boots, with a glow-in-the-dark O-ring in the head, so they look pretty slick as a family. Thanks to Ricky at Lumapower for supplying the LM21 for review. I’ll be reviewing the LM21 in two sections: first, I’ll discuss the light objectively (the facts about the light itself), then I’ll discuss the light subjectively (my impressions about the light's performance when used for specific applications). This is a tiny AAA light, designed well for pocket EDC, so I'll be reviewing it as such. If you have any other specific applications you'd like the light tested for, let me know and I'll see what I can do. Objective Spec-Check In this section, you can see a quickly if I found the claims made about the light to be true. Packaging Construction Quality Coming Soon... Action Shots Light in Hand White Wall (Low, Medium, High) ISO 100, f/3.3, 1/10" BeamSlice MugShot Indoor Shots (Control, Low, Medium, High) ISO 100, f/3.3, 1" Outdoor Shots (Control, Low, Medium, High) ISO 100, f/3.3, 2.5" Mid-Range Shots (Control, Low, Medium, High) Performance Coming Soon: submersion, heat, PWM, drop, polarity, protection, etc Spectral Analysis All light that we see as white is actually made up of several different colors put together. The relative intensities of the different colors in the mix are what determine the tint of the white we see. For example, cool white LED's have a lot of blue, and warm white LED's have more red or yellow. This measurement was done on a home made spectrometer. Note: the peak in the 900nm region doesn't really exist, it's a piece of the second-order spectrum that's showing up here because of the high intensity of the light source. Coming Soon Current Draw Coming soon... Runtime Note: The vertical axis of this chart represents a relative brightness measurement using a home made light box. The horizontal axis is time in hours:minutes:seconds. Runtimes are stated in hours:minutes:seconds. High (Trustfire 10440) Time to 50%: Full Runtime: High (Eneloop AAA) Time Regulated: Time to 50%: Full Runtime: Medium (Trustfire 10440) Time to 50%: Full Runtime: Medium (Eneloop AAA) Time Regulated: Time to 50%: Full Runtime: Low (Trustfire 10440) Time to 50%: Full Runtime: Low (Eneloop AAA) Time Regulated: Time to 50%: Full Runtime: Subjective Review General Quick break down: + - Coming Soon Mini-EDC Coming Soon Long Term Impressions I'll fill this part in after carrying the light for a while. If nothing get's added here, either I find nothing else worth noting about the light, or I end up not using it often. |
