Reviews

It is always a good idea to find out what other people think of a light before buying. There are some good places online that provide professional reviews with information about light output, runtime, and features of a light. If you look under Flashlight Manufacturers and click a brand listed there, there are often links to reviews of lights. Here are a few websites that offer flashlight reviews:


 * Light Reviews: - A nice website with hundreds of reviews of lights, constantly being updated with the latest flashlights.


 * CPF Reviews: - CandlePowerForums posts reviews in a special subforum. Reviews by user Selfbuilt are well-written and include a wealth of beamshots, runtime graphs, and comparisons with other lights, but all reviews in the sub-forum are generally good (the CPF moderators hand-pick reviews from other subforums to include in Reviews). See a list of all of Selfbuilt's reviews here.


 * Budget Light Forum: - Reviews for budget lights are stickied in each subforum based on battery type. Some lights will have reviews by different authors in separate threads. The budget light reviews page has a compilation of all the reviews in a sortable table.


 * Jayki.com: - Reviews and news of mostly budget lights, but also some higher end lights.

For China-based budget light brands, always check out the reviews and comments at DealExtreme. While some sites use fake comments, DealExtreme comments seem to be genuine. Because they don't rate reviews as helpful like Amazon does, sometimes you need to read older reviews to get a better picture of light performance. Be aware that specifications and quality can be variable and budget lights seem to start out higher in quality and degrade over time.

Measurements
These sites don't do full reviews, but offer some good information.

Fonarevka - This site has tons of outdoor beamshots of popular lights. It is a Russian site, but this link goes to an English version.

Budget light output - Readings of a lot of popular budget lights at Budget Light Forum. Also tabulated here at Flashlight Wiki on the Budget light output page.

Lumen Readings - This post at CPF by bigchelis has lumen readings taken in a calibrated integrating sphere. There are a lot of readings of custom-made lights and P60 drop-ins, but also production lights. Older readings taken by MrGman are posted here.
