I ordered the SRT3 and SRT5. I currently have been EDC'ing thet SRT3 and the SRT5 is going to get carried only when I know i'll be going outside, in the winter with gloves on sometimes, hiking, camping, and nightstand use. Both will be used in conjunction with a handgun and I will train with both.
The light settings are awesome. The red and blue LED are both fantastic at their purpose. Red comes in handy with maps, low light moving around, etc without ever blinding me. If I need more light I easily and quickly switch to blue. The light moves brighter and dimmer smoothly. I really like the strobe function on this light. The flashing red and blue doesn't have a whole lot of regular use for me. I've thought of some ideas it could legally be used for defense styles and warnings. Though if I had to use them I'm probably not in a good situation. I'd rather have tools I don't need, but the red and blue built into this light is awesome.
