“Fantastic, I definitely need this comparison. I've been contemplating the M21B LHP73B. But i love the well defined smooth beam in the L21A now that I've seen it. What's your preference now you've had them both of you could only keep one and why?”

“I have almost 50 lights. Here's my five favorite at the moment. Convoy T6 w/ SFT25 6500K and forward clicky switch - tiny pocket thrower with great output and reach. Has completely replaced my S6 CSLNM1. Emisar D3AA 519a 5000K DD - great little EDC with tons of output and a very efficient driver Convoy L21B w/ SFT40 6500K and forward clicky switch - ridiculous amount of throw with a lot of output for not a lot of money. Great driver too. Skilhunt H150 w/ 519a 4500K - small, lightweight, dual fuel headlamp. Emisar D4V2 dual channel w/ 219b 2700K/4500K - I just really enjoy having this set this to auto tint ramp. The way the CCT increases with the brightness makes me happy, and 219b makes such nice looking light.”
