:cryyy:I use a 1.2W 445 to kill snails in my fresh water tank. It is more than enough to boil them in their shells, often with a satisfying "POP!"
Pretty sure he just wants to buy the 3W laser and is looking for someone to help him justify the purchase. LOL. I have already explained that for this purpose the 1-1.4W laser would be ideal considering you will need LONG duty cycles to take care of everything. That and 1W is still a CRAP LOAD of power. It is very frustrating to me how so many noobs lately are seeing a couple 3W lasers being built and all the sudden a 1W laser is no longer good enough. As if 1W has no power.
