depends how much bigger or brighter? ... I have one of their PD35 Tac lights and it's one of my favorites ... runs on one 18650 rechargable ... it's plenty bright has the same tailcap ...
they just released an UC35 that shows slight improvements in throw and lumens with some other features I haven't looked into it alot yet ...
But the PD35 Tac is still small enough to carry easily and plenty of brightness and features ...
the LD22 is a good light runs on 2AAs and has better brightness is thin but longer ...
if you want some bigger and brighter with longer throw the TK25 runs on one 18650 rechargable and offers an optional red and blue light modes ... the secondary tailcap is instant strobe ... or once the light is on it adjust brightness ...
The TK32 has longer throw ... the secondary tail switch is automatic red and green light both in bright and dimmer modes ... and is the brightness for the main white LED if you turn it on first ... and the throw is great ... it also runs on one 18650 rechargabe.
if you are looking for a slightly bigger light then what you have that is still small enough to carry and gives you brightness and a strobe feature the PD35 Tac or maybe look at the new UC35 ... I love my PD35 Tac.
