    Is a very good and portable flashlights. I ordered the Tan colour with 6500 sst40 led. Good beam and range. Very pleased with the flashlight.

    Model M21B XHP70 3.0 R70 4000 K. First of all, I want to highlight Simon's excellent customer service. Also, my opinion that their products are excellent value for money. The M21B is a very good medium-sized flashlight. An all-rounder that works very well for outdoors and indoors. The negative point is the LED I bought. The XHP70 3.0 R70 4000K has a very nice yellow-gold tint, as reported in many reviews. But it produces a very annoying beam. It has a large hot spot of a noticeable blue-purple color. It also has a transitional crown towards the spill of a certain greenish tone. This is a product of the mixture of the beautiful yellow-gold and blue-purple color. To me, this is frankly annoying and very disappointing. According to Simon, this is produced by a slightly wrinkled orange peel reflector. Perhaps, other LEDs will have a nice beam of light with the M21B.

    M21B is my favourite flashlight host. Brown and orange were bought for friends. Good size for pocket carry and easy moddable.
