uv light is more dangerous than ir :) they cause some optical and medical problems(in some cases skin cancer)

no i mean uv is from 315 to 400 nm I have 200 mw 405nm laser and it is known as violet or near ultraviolet laser and is 5 nm that much to change 400nm ultraviolet to 405nm violet/near uv

Ok I have read that uva light (315-400nm) are actually harmful to skin but does 5nm make that big sence?

hello, i have heared that ultraviolet rays cause skin cancer and cataract so will 405 nm wavelenght laser harm me, are there any chances that i will get a skin cancer? uva lasers which cause skin cancer is from 315 to 400 nm, 405 nm is only 5 nm longer that 400 so is it harmful?

i ordered laser from play-laser.com more than 30 days passed and i still haven't recived my order, i wrote to them several times but no answer. so is this site trusted and will my laser arrive or am I fooled?

I can read Max.Output 200mw on laser pic. so, does it mean laser can be modded up to 200mw or is it another lye?

Thanks for answering, will pot modding decrease diode life time?

Hello everyone, I ordered this laser 2 days ago: High Quality 405nm Portable Blue-violet/Royal Purple Beam Laser Pointer I Know what it will not be true 200mw but can you tell me approximately how many mw it will be, i want to use it to pop balloons

I' don't want such a powerful laser, just to light matches and pop balloons, so should i buy it?

Should I buy one of these lasers they all are 100 mw, but there is not written if they burn or not, 100 mw should burn right?
