Skytech is selling 2 lasers that interest me:
1) A blue 450nm laser pointer that can switch between 5mw and 80mw and they cost about $90 usd
2) A blue 450nm "handheld laser" with a ton of keys ans stuff that is 1w! for only about $160 usd

could anybody tell me what a 80mw blue laser can do? is it visible? and is it worth it to just get the 1w, which one is the best deal. I have a few green lasers and im looking for something more visible and powerful
here is a link to the company: skytechlasers.com
 





As this is your first post, welcome to the forums whenwhalesmoo!

First off, do you have proper safety glasses?

I will be purchasing them before I purchase either of these, but its not worth getting goggles if i dont choose one. I WILL get them before i get either of these lasers. As of now i only own >5mw lasers

Ok, good. Did you need a link to quality safety goggles just in case?

To answer your question, it all depends on what you want to do with your laser. 80mW's of 450nm won't be terribly bright, per mW it will be dimmer then a similar laser at a wavelength of 650nm. A 1W 450nm will be pretty bright and fortunately, won't kill your night vision if you decide to use it outside. Honestly, for 920mW more, $70 is a steal but it's all up to you :beer:

Check out the below tool if you want to experiment with different brightness levels: Relative Laser Dot Brightness Calculator: (450nm 80mw) vs. (450nm 1000mw)

Do you think the 1w one is legitimate? they have videos on youtube where the 80mw looks very similar to the brightness of the 1w one. they only show the 1w one burning :thanks:

It should be. laserbtb gets their lasers from skytech I believe.....if im wrong, someone please correct me. Most lasers from them then to be overspec(more power then what you pay for) and have pretty decent build quality :)

laserbtb bought skytech, not even sure why laserbtb exists because skytech looks way better and has the same lasers. Thank you so much!
 
Is it your first high power laser? If so I will recommend taking the 80mW one. 1W maybe a bit too dangerous to be your first laser.
 
If you want to burn, you won't be satisfied with the 80mW one although it should be a very nice unit with some visibility in a darkened room.
If you really want to burn then the 1W is a no brainer in comparison and the beam will be quite visible.
If you really want to burn you are far better off looking into a 405nm instead although the beam visibility will not be very good even at 1W.
If you want very visible then any 532 or 520nm 100mW or greater will have a nice solid beam.
Regardless, eye safety is king and you must be fully aware of proper handling at all times.
Be aware that if you are looking at a pen laser all the ones that laserbtb sells are not focusable as far as I aware.

There's always members reselling their used lasers here also if you can meet the requirements of the selling agreement. I've gotten some pretty amazing deals here. Just be aware that some people claim to be good builders and are not. The bigger the bargain the more likely something isn't quite right (I've fixed probably 1/2 the ones I've purchased although the issues have mainly been poor soldering, faulty switches and cosmetic).

1W lasers arent that fun, they are way too powerful even looking at the beam outside is dangerous they are good for burning i would go for a lower power even blue 80mW is visible in the dark but not as much as green lasers of course.
 
You won't find anything more visible for the power than green, especially 532nm. If you get a powerful enough 532nm, it can burn too but the price is high compared to 445nm blue. If you want something which is fairly bright in a darkened room and will burn, a host with the NUBM44 is the ticket with one exception, it's divergence is terrible compared to a DPSS green 532nm laser. Couple the 445nm with a beam expander you can focus to a spot too and now you have a low divergence bream which is fairly bright at 6 watts out as well as one hell of a burner, but not for the price of those 1 watt blue 445nm pointers.
