Considering the size of this host, your duty cycle will likely be around a minute. The two are the exact same host. You'd need a rather large (and expensive) heatsink to get a continuous duty cycle at 1W of 445.

Nice research, wonder why you didn't find this... Cyber 445nm - 1W Focusable Blue Laser Water Proof Same exact thing, $100 cheaper. Plus they're trusted. Don't know about BigLasers, but definitely overpriced. As well as the fact that WL lasers are crap.

Damn that's awesome! Looks like a huge white laser :D

Yup, you'll find this forum has lots of resources, just need to search for them or ask! :D If you have any other questions, you can PM me or any other vets and we can help you. Probably should read up on laser safety if you're new to lasers though

No one else has had problems with O-like, so again I reiterate; if you have any questions, email Susie who will sort things out. They are a trusted source and have good customer service. Unless they suddenly began scamming people in the last 24 hours, I just received my 50mW module from them no...

Learn how to use the search button please. O-Like is a trusted supplier and Susie has good customer service. Email her if you have any questions. Also, you're getting a 1W 445 laser. You need to get laser safety goggles for that.

Well depends on how you're using it. If there's even a remote chance it'll get in someone's eye, then about 10mW is the max limit, and even that's rather dangerous. However, if you're simply pointing at things on the wall, floor, etc., without risk of reflections, then up to about 50mW of green...

His name says silver, but it's more like lead. Poisonous to everything it touches and rather dense.... on a more serious note, there are lots of places to get 18650 batteries....it's called google.

Re: 300-400mW Green Laser (Output Tested and Confirmed) $210 Shipped That's a bit low there....considering everything he's throwing in hahaha.

Read the rules of the BST section, post pics with your name and date, lower the price to something reasonable, and then come back. Because right now, it's just about the worst thing anyone could do to buy from you. No reputation, no name made for yourself, first post and you're already giving...

Yup, usually labelled "flashlight".

You're starting off with a 1.3 W laser.......? Sounds sketchy.

Welcome to the forum, and remember to use the search engine for any questions, then ask if you can't find it. :) Enjoy your stay here!

You could probably get about $280-290 for that, if the host and everything is in perfect condition :)

PM sent!

Thanks :beer: edited to reflect the correct info now!

Re: Jayrob DIY green kit-$30 How large is this host? length, diameter?

Lazerer and O-like are two good, cheap and reliable companies. Cost will probably set you back $70 ish. 100-200mW should be quite enough, just don't point at anything reflective since it could damage your eyes. Your original purpose should be just fine though.

I believe relative brightness is a x^2:x ratio. 4 times the power equals 2 times the brightness, 16 times the power equals 4 times the brightness. What do you plan on doing with the 400? it might be painful to look at that indoors :p the lower the wavelength the more energy is absorbed, IIRC. so...

haahahahhaha fap. sorry, had to :P but that looks awesome, good job!
