I'm not familiar with the Solarlight L2 but I looked it up and it looks like it takes P60 size drop in, right? When Gene Malkoff was making his P60 size MC-E, I wondered what the hub bub was and decided to drop my MC-E Dereelight pill (which is usually in my DBS v.3), into my Dereelight CL1H, which had a Malkoff M60 in it so you know it's a P60 drop in. The size difference in the beam profile was pretty big. As you can imagine, bigger reflector, bigger beam. Since you're already familiar with the DBS, why not get another one with the MC-E and the specialized MC-E reflector? I hear those maximize the throw even more. I did notice there was terrible heat coming out of the CL1H after about 3 minutes. I run my DBS with an MC-E with no heat problems up until about 20 minutes. Everyone has different heat tolerances, though so it might not be an issue for you.
If you go the Deree route, don't forget there's a US dealer for Deree:

He's in California and ships VERY quickly and reliably. Jay will take care of you! Tell him John sent you!
