I own MT21A and MT2A Nitecore.
Good lights but the MT21A is a thrower, between the two I prefer MT2A which makes more lumens and has a balanced beam good for most situations.
They are a few years old lights but MT2A can still be a decent light.
I recently bought a Fenix E20 (2015 version) it is built very well, I like that you can change 4 light levels from the rear button.
Even E20 is a thrower like MT21A, inside the house the narrow beam is not good but a piece of transparent Magic tape is enough to solve the problem and have a wide beam.
Otherwise look at Fenix's LD22 which can be similar to MT2A as a beam.
If you want warm light look at the Trunite Archer2A, I don't have this light but it sells a lot even if I don't like the spacing of the light levels (jump from 75 lm to 500)
Armytek also offers models with warm light.
