E-bay Green Module - Not Bad!

jayrob said:

Most modules at this power can run from a 3.6/4.2 supply. But keep in mind that it is a cheap module...

I don't have any solid answers, but just sharing what I found so far. We need more people to buy this module, and report back with their findings...

Might be a good experiment to use a silicon diode with a Li-Ion...

Thats what I meant, A diode. I have a package of 1n4002 diodes.
I think it drops the output to about 3.6 from the full 4.2. Plus that 3.6 will drop even further under load.
I'm going to give one of your modules a try in the next few weeks. I need to recover some funds from my last big purchase.

In the last 2 months I have ordered 4 532nm modules.
If these turn out to be similar in quality, to the low cost Chinese import modules we've been buying. You just might find yourself with a solid customer base here at LPF. No more waiting 12 to 28 days for shipping from china

However we our a Hobby forum first, not a retail forum. We don't mind retailers coming here to hangout. If you want to push your product do it appropriately. Most of all, be honest with what you sell and how you sell it. Don't boast, just be humble. Over time, the forum will make it's own opinions on you and your products.

Were not so much concerned with how good or bad the quality is, but more so with how you present it.
Their is one chinese retailer on here, who does a lot of business. One of the things she does that is a plus. Is that she sells her modules in ranges. Like her 150mW module, is actually a 130-150mW module.

I have red the message above, and i dont mean to push my product but today my listing was removed from e-bay for vialation....... This is the second time this has happened and i dont think i will be able to list it again unless i want them to close my acount for good(it may possibly get closed this time). Now im going to be stuck with a bunch of 200mw 3v modules (50 to be exact) and i have no way to advertise them.
I want you all to know that i will run a sale to sell what i have left, and if your guys want to continue ordering after this batch of stock with the modules i can get i will keep a few in stock just for you LPF users however the price may be slightly higher.
Thank you and i hope you understand.
The sale will be $72 shipped to your door anywhere in the us.

You seem like an honest seller, and I know that I am happy with my first module that I tried out...

But if you had a power meter to test the output of each module that you will sell, then you will easily sell them.

People like to know what they are paying for. I took a chance (knowing that it would not be 200mW's), because the price is right...

Also, you should get a simple heatsink to put them into for testing.

I can trade you one of my hexagon heatsinks, plus the difference owed for another module. But I would sure like to get a high output, and stable one!

Here's the heatsink:

How much for the heatsink, i would be willing to work something out.
Yes i do need a power meter. Im new into selling lasers and have been investing more into product to try to get the cost down so i can actualy make a profit to buy the correct equipment to send laser output test with my modules, im sure you as well as everyone else knows it cost money to make money and right now im not making very much im just trying to get out there I apreciate all your support and help along the way. I will have all the equipment soon to provide detailed and acurate information on every module i sell.
I saw someone using what appeared to be a handheld battery powered meter any idea how much they cost and where i can get one?
Thanks

One of our forum members sells those (lasersbee) give him a pm I think they are around 60 bux...

Received my module today from nexbox360.:wave:
Too tired to do a "real" test, but, running it off of one RCR2 3.0V,
I'm showing 190mW within,<2 seconds. Levels off to around 175+, after 1 minute. W/ excellent divergence.
It will light a match from 3' away!! In a second!
Perfect TEM00 mode, very thin beam.
It's looking good fellows.
Of course, more and better tests later, with plenty of beam shots.
Also some IR tests and Vis. output tests, to come.
:thanks:nexbox360

These sound really nice then. I still need to get a decent heatsink though. DX used to carry those nice blocks with a 100 mW (or so) red module, but they are sold out... any ideas?

I received mine today, btw, brand new here. I have a 100mw green and this thing blows it away. Running at 4.25 vdc and takes around 45 sec before it gets warm. Very tight beam and very bright. Cudo's to nexbox360

Voltage on this module is 2.7-3.0V. I would not run this module at 4.25V
Below is the heat-sink I built for the module. Running at 3.1V (Fully charged RCR2, under load) this heat-sink gets warm.IE: not WARM,warm, but you can feel the temp. difference, after 2-3 minutes, (of 30 secs. on/30 off)
I'd limit the duty cycle to 10 seconds @4.25 IMHO.
Unless your heat-sink is bigger then mine
Or you are using a low current PSU, which would drop down the V's under load.
Also shown, some down and dirty mW readings.
Heat-sink and host


3.1V Peak

After 30 seconds.

After 75 seconds. Heat sink started getting warm so I shut her down. And my hand was shaking!

More tests to come.

Thanks for the info, will only run at 3.0.

The hexagon heatsink pictured is $23 dollars plus $3 dollars shipping...

You will need a 1.5mm Allen wrench for the set screw. (wrench not included)

I can send it, and then wait till you get a meter, because I want one of the 'HOT' ones. (stable)

Just contact me on here and we can arrange a sale. Yes the listing was removed on e-bay but it is back up for sale. Im currently out of stock on the units but no worrys the factory is producing my order as you read this. It takes them about 3 days for my order alone and should be here sometime early next week.
The $72 sale will still remain but will be ending as soon as i recieve my stock, so this sale is for pre-sale orders and i give a discount as i appreciate your patience as it could take a week or two to get to your door.
Thanks for the reviews guys im very glad your happy with my modules. Soon i will have my own power meeter and i can test it before sales and include the output power for each module with the sale.
Thanks again guys

If you still have my address sure send one my way, i will be directing people to you for those heatsinks as i get many questions on where to get a decent heatsink and not break the bank. Do you have an e-bay account with them listed if so i will include your listing link in my listing and its sure to bring you sales it not let me know what link i should use to direct them your way.
My stock should be in early next week, You can send the heatsink my way and when i get my modules and get the meeter i will shipp you out a module but you will have to make up the differance.
Im looking to get a nice meeter from an LPF member looks easy to use and works with all colors and appears to be quality and stable, the link bellow is someone who uses the same meeter i shouldbe getting.

sorry for the mixed up messages guys, i will try to put your user name next to the person im responding too, i realize this can be a mess and hard to read if you dont know who im responding too.
