Portable light (back-up light) in regular Lumen
Of all the compact lights below 700g, there are some limitation on lumen due to its SIZE. In the market, there are various options, however, ARE THEY ALL REAL?

Estimate by Lumen & Reflector
One of the most important is the size and design of the reflector matched with a suitable amount of lumens to achieve the results. Some torch would create the brightness atmosphere around you with 20mm diameter reflector, but it will only light up the first 20 meter well. On the other hand, different reflector creates different brightness. So a balance of lumens and reflector are important.
Strong lights cannot accepted in small torch
1. Putting such a high lumen output level into a flashlight with a small head, the flashlight would become too hot to hold in hand, as there is not enough space for releasing heat.
2. They think it is innovated to have strong light in portable torch, however, there is a limitation of light distance in such diameter and depth of the lens. In other words, the light won’t go any further, but spill all the light to the sides, which is just a waste of power. Most good quality torch around 200~400Lumen will give you more than enough light to the sides.
So far, have you had an answer in your mind, across the above picture, which torch would be more reasonable at the requirement of good quality, less waste of power, regular lumen and reliable torch?
I think you have already found your own answer, so does the clever customer.
