Some (on page 1 and page 3) are clearly identical to Dorcy's LED lights (like the 1AA 3 LED light), although at much higher prices they they usually sell for around here. Some others look like Dorcy variants (more batteries, incan versions, etc.) using the same basic shells and parts as the Dorcy's.
By and large, they look like reasonable but sort of last generation's LED lights, and at fairly high prices for here. Don't know about for Australia.
For these kinds of prices, places like
J2LED ,
Fox (Streamlight Propolymer Luxeon 4AA], and
Lighthound provide much nicer or much cheaper or both lights, and I think all ship internationally.
BTW, welcome to CPF!
