E-bay Green Module - Not Bad!

[jayrob]

I decided to try out one of these modules after talking to the seller...

He had admitted that most are probably around 175mW's. So for the price, I figured it was worth a try. And I am happy with what I got for the money...

I put a heatsink on and tested it with two different batteries: (basically no warm up time with it. It went right to the peak with-in 5 or 10 seconds)

* CR123 - Peak power was 142mW's and settled at 130mW's steady. (30 seconds)
* RCR123 - It was already warmed up, and went to 165mW's. Stayed steady at 160mW's. (30 seconds)

The current draw (from the battery) on the module that I received, using an RCR123 rechargeable battery, is 745mA's. And at this current draw, the module is giving 160mW's...

Not bad for the price!

He also told me that he would sell them for $75 shipped. (outside of e-bay)

160mW's for $75 bucks... Not bad! Hope they're all that nice!

Just tell him that you are an LPF member...

Thanks for the review.
I decided i should probably make a username once you braught this website to my attention, thanks again.

Looks good. You may want to spell check your eBay ad.

Hmm there wouldn't be any way to fit one of these into your DIY Green Kit, would there, jayrob?

Sounds like good bang for the buck!

What is the size of these modules (diameter, length), and how much current do they draw?

Perhaps they could be suitable for mounting in a (big) heatsink and continous operation...

Hey Hak....
what's with the blind man font....

Yes! My DIY Green kit will fit any standard 12mm module, and this one will fit right in there... (won't fit the smaller SS C3 'Mini Green kit' though - too long)

One thing with this module, is that it has two lead wires. It also has a spring. (Mine does anyway) But the spring is not soldered to the negative contact point. It would be very easy to solder a bridge to the spring, and use it in the normal way though.

Mine doesn't have a switch on it either. Which is good for me, because I will be mounting it into a host/project with it's own switch...

well jerry its not as large as you quote it and the user that asked -how big? may be sight impared as i found it without my readin' glasses--lastly no font is big enough for a 'blind man' to read IMO LOLOLOLbut thanks for asking----hz

Thanks for the info! Always good to have a member take a risk for the rest of us. Its very much appreciated!

 

[nexbox360]

sorry about the spelling in the listing page everyone. Im more of a mechanicly enclined person wrather than book smart. My spelling has never been good.
Thanks

Just ordered one of these.
I have both a IR pass and a 532nm pass -3% filter.
I'll post the results as soon as I receive it.:wave:

Hey this seller is located in the U.S. selling modules at chinese prices

Jayrob, you say you ran it of a rcr123 cell, 4.2v did the driver seem to get warm fast?
I like using rcr123 cells, mainly because I have so many. If I use a resistor I can drop the voltage down to 3.7 from 4.2.

 

[nexbox360]

Im looking forward to the review with the IR output and green output i have never had anyone do them seperate as you can.
Your module will be shipped out tomorow, im shipping you one that seems to have a very strong green beam and also light a match at 12" in a couple seconds with my unsteady hands with about 5 seconds warm up time using 2 D energizer batteries with an experation date of 2009 (cant wait to see the results). Should be a good one fore your test and review.
If you guys are statisfied with my modules please add rep to my account as im new here and could use a couple points
Thank you

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...

I use the 18650 batterie here and there on some modules that i would not ship to my customers due to lack of output, and they get very hot very quick. Im not sure how long they could withstand this high of voltage going to them im also not using heatsinks just doing quick 10-30 second burst. Please closly monitor the temp and output as they are ment to run on 3v and i wouldnt want anyone breaking them.
