Got my 500mw Green UltraFure From Price Angels!

I hope this is the right forum to post this in,

As a relative New-B I'm trying to minimize the risks, but one I had to take was to buy a Green laser from Price Angels. I saw on the forum somewhere people were talking about Price Angles being legit, but I couldn't tell if they were "real people" like me or if they are from the company.

So I bought this for $46.12: http://www.priceangels.com/UltraFir...Pointer_WF-502C_1*18650_Included__p10836.html It took about three weeks to get here which is a long time to worry about whether it'll make it, but in the end it was worth it! I think I'm going to get a 300mw from P.A. soon.

I wish I had some test equioment to check out the power claims, but I can say that it is brighter than anything I've held.

Come to think of it, the best I could compare it to was when I fried one of my A140's by accidentally over amping.

If anyone has any experience with this or a similar model I would love to know the duty cycle on this thing.

*ack* I just failed to get any images to attach...in fact I can't even get the attachment window to close now ....Where is the test forum?

just click the red x on the top right of the attachment window to close it. For pictures, you can just resize them to 800 x 600 and upload them to photobucket or some other online photo-sharing site. Then just copy the url of the picture and click on the insert image button (right of the hyperlink, and insert email buttons). Then just paste the picture url there. It should show up in your post.
There is no way that is 500mW. It is also probably like half IR. But there is no way to tell without testing it with a LPM.
You need to get safety glasses for it. I would suggest DragonLasers or RadiantElectronics for good ones. You can get the radiant shades for pretty cheap and there is a discount for LPF members. There is a thread about it in Deals and Discounts section.
I would turn off the laser if it starts to feel warm. It depends on how powerful it is. If you don't know then don't run it for more than a minute or two without turning it off for like 2-3 minutes in between.

Hey thanks for the reply,

The browse for file button would 'depress' but didn't do anything - and then application sort of just sat there not working, but unable to close (but would minimize)...not a typical freeze up like I'm used to. It had to be shut down forcably. I will do some updating (java, flash, etc) and give it another go after work today...It's annoying but I don't like auto updating...
I teach AutoCAD and coputer classes for my union, and use Autocad in my day job > 3,000 hours a year so I'm used to applications freezing up, but for some reason I never get used to it!

You've given some good information - I've been lurking for a while and I appreciate how safety conscious most people on these forums are, and how helpful everyone has been. I hope to be able to help an some small capacity when and if needed but for the time being - I think I'll kick in $10 to the cause....

Even with the several OSHA safety training classes I've taken over the years I still find myself taking safety shortcuts from time to time - but generally not with my eyes. Still, I do need some good safety glasses but don't want to get taken advantage of. I've seen a wide variety of types - and prices! I will check Dragon Lasers & Radiant Electronics out. Is there a such thing as a good pair for around $20. I saw some crazy kid in a video pointing a laser at his face with his home made glasses! LOL too funny..

As for the laser I was all giddy about, I was hinting (in my initial excitement) that it was putting out a little more than one of my A-140's at over an amp (but that of still subjective to the lpm). I need to save for an LPM apparently...or can I build one?

Also, This laser pointer doesn't get noticebly warm after a minute, but that's about as long as I've run it for. I have a pretty broad knowledge of how to break things so I try to take it easy at first.

I will be exposing the internal assembly after running it later today (again after work).

And you mention IR, and I am guessing it's got an 808nm diode in there with a filter - does that sound right? I've got a couple of 300mW 808's on there way from China - and I want to get some filters if that's the way to do it (still reading up on it on my breaks at work) and every week I'm collecting bits and pieces to go with the 10 or more diodes and laser pointers & modules I've collected over the past month or so..

I promise to get some glasses asap!

The Radiant Electronics pair are probably the cheapest around that are any good.
The only way to test the true power of the laser is with a lpm. If you use the search bar, you can find threads how to make your own. I wouldn't recommend making one of the ir-thermometer based ones because they aren't very accurate. Other options from making your own would be the Radiant Electronics Alpha or the new 2.5W Laserbee.

I doubt it will have an IR filter so you may want to install one. The IR is not focused so as long as you don't shine it at someone's eyes, it should be a big deal. Some people like to have them, others don't see the point. You will need an IR filter to test only the green output of the laser. Some highly trusted members here might test it with a lpm. You can also see how close another member lives to you:

Feel free to add yourself to it too.

Also, I'm sure no one would object to a review of this laser either. There are many examples in the Reviews section; or you can look at my first review (cute red laser), my second review (o-like 405), or not really a review, but my newest one (my 1.4W 445).

I've finally found some time, and I'm googling & reading up on LPM's while looking at some things I want to buy, typing this follow up/thank you letter - while watching tv and playing with an a140 and my latest host...For some reason one 9v battery just doesn't work as well as 6 1.5v AA's for about the same voltage (even 5 aa's @7.5v worked better) but I 'spose the 9v just doesn't have enough in the pants for the LM317 circuit I'm using..so I have to wonder (and this isn't the right sub forum to wonder this) if I just used two 9 volts in parallel if that would be okay too?

The host I made was for a 9v, the next one will either have 6 AA's or two 9v's...

Ok back on topic (this post is taking some time!)
Looking at all the used parts on Ebay, I'm not going to buy anything until I understand a little more...and I like the idea of buying building one unless I can find a good used complete getup for the same price (is that even possible?).

Anyway, I just wanted to thank you for sending me in the right direction!

Lasers are fun!

Using Li-ion or LiFePO4 batteries are best for high drain devices like lasers. 9V batteries have very low current specs. AAs would last much longer and run the laser better. But lithium rechargeables usually are best for lasers. 6 AAs will have longer run times but their voltage drops faster and they take up more space.
I know their are many threads here that talk about that driver. I personally have never used one so I don't really know much about it. I believe 2 18650s in series (7.4V nominal; 8.4V at fresh recharge) work pretty well as well as give pretty good run times. Don't hold me to this though.
My first high powered greenie uses 3 AAAs @ 4.5V and I can't use nimh rechargeable eneloops in it. If I use alkalines, they only power the laser at full brightness for 5-10 min before dimming. Alkalines drop voltage pretty fast under load. Lithiums keep the voltage longer before dropping.
Lasers and I have a love-hate relationship. Lasers are fun when they work. They suck when you have to wait for them to arrive or if they die.
Glad to help :beer:

omg.... stop spamming.... :scowl:

Hi, if it was advertised with 500mW for this price you can divide it with 10. So i guess your Laser will have about 50mW.
I ordered five pieces 50mW Pointers and three of them are under 5mW.
Shipping was :spank: but i dont wanna bore you with another dropshipper story.

Somehow I seriously doubt it's only 50mw, especially since I've compared it to the output of an A140 @ > 1A and it is very nearly as bright as that. I see I'm going to need that LPM in a hurry to keep my bragging rights!

It's probably more than 50mW but comparing it to the output of an 445nm diode running at >1A is not a very good way to judge it's output.

Using a program called chroma and taking Rayleigh scattering into account, 1W 445nm = 99.270mw green to the human eye. That is a good estimate but everyone's eyes are a little bit different and sensitive to different wavelengths. :beer:

haha yeah, its probably 300 or so total; less of green. But that's just my guess. If you want one fast, go for the new 2.5W laserbee I linked to in my previous post. Those are sent I think with priority mail or first class.

Yeah, of all the LPM's out there, I'd go for that one. For the price it's hard to beat.

Your also going to need an IR filter to see how much 532nm it's putting out.

I believe you can get a good IR filter cheap from Radiant Electronics.

I got the same suppliers 500 mW and mine does 90-100 mW at best... that includes any IR present. -Glenn

Dang... that sucks. Hopefully cad602's isn't that low.

I love this kind of peer pressure! Even if I'm prolly a ~little~ bit older (just a guess!)..

When the wife goes to sleep tonight I'm going to order one!

I can only do so much one can do while watching Phineas and Ferb...*cough* with the kids of course!
