The Romisen RC-29 looks interesting, anyone have one?
what's the difference between regular and neutral?
Of the lights mentioned so far, my experience suggests that the Quark Mini AA (or Mini 123) with the XPG emitter will offer a floodier beam. The older model (about 6 months older, using the XPE emitter) will offer better throw.
The Quark 1xAA will offer the best of both worlds. I recommend using it with a 3.6v 14500 li-ion rechargeable cell, for really sweet output.
Romisen RC-G2 has a nice spot & very good spill. IMHO
