..so.. if i want a good 50mw pen unit.. it is the same thing go with dealextreme or ledshoppe ? ? ledshoppe however seems to have the higher % of overpowered green laser. but .. i heard that it has large beam diameter but low divergence. is it true?
Its true, the beam from the ledshoppe pointers is much 'fatter' than that from the dx ones.
At larger distances the difference dissapears quickly, and i think the ledshoppe one might actually do a bit better in the far field (divergence/beam diameter tradeoff).
