Hello everyone, Some time ago I built a laser with the following setup: Diode: NUBM44 (7W) Driver: SXD 4.5A Host: Survival Laser Power: 2× 18650 Li-ion batteries The laser worked fine for a while, but recently it suddenly stopped working. A friend helped me with the build and did all the...

Sorry...I did not understand.. What's strange? I'm just selling a product that I bought, assembled and I'm no longer using. Do you have an offer?

Findind a new home for this beast! - NUBM44 Diode w/ G2 Lens - SXD Super X Drive set at 4.5A - Ceramic 2 Thermal applied (accompanies, is full) - Thermal Alumina A and B (accompanies, is full) - S4 Host from Survival Laser - This host is running with 2x 18350 but i'm sending with 2x new...

I found this tutorial.... my question is: What's the problem if I use the original diode pill, not the half?

It's been a long time here at LPF... all this times wishing to build my own laser... this year, finally I just bought some parts from SL... Host, Drilled driver, heatsink... I'm so excited to receive them and finish my build... Thanks Gary!!!!!!!

I suggest you to contact Lifetime17, he has nice hosts for your or if you want, check it out Survival hosts.. I just bought a S4X, NUBM44 V2, SXD 4.5A to run the same power you want. Big hosts are better for higher power.

Great! How about a NUBM44 7W - in a S4X host from Survival - SXD Driver 4.5A, Copper Heat Sink? 2 on / 2 off is good?

Thanks, i connected through the driver, then I could see the low light.

Hello guys! Since 2015 I have a Sci-fi laser 1 - 1.8W 445nm (not sure the power) and my drive burned completely .. does it affects the diode? The diode light is very light when I turn on conecting directly. How can I know if my diode is still good? Also, the main question: How can I know...

Thank you my brother!!! I was thinking why not buying a new one ready for use instead the job to assembly without know weel what I'm doing... I saw this morning a Survival Laser lll, 2.8W.. is this a good company and their products? Is there any other recommendation? Thanks!!!

Hello guys!! I have a sci-fi laser 1.8W blue (model 501B) that I acquired in 2015 from Eitan and I would like to put new parts on it and use only the body. I don't have any knowledge to be able to assemble my own laser. Could someone help me what parts should i buy and where to buy to mount a...

Hi folks! I hope you're doing well! First of all, I'm completely beginner without knowledge in lasers, diodes etc... sorry my ignorance in some themes... In 2015 I bought a laser from Sci-fi lasers, (2.4W blue) I bet some of you know this company... unfortunately my laser died it's been a long...

Welcome Gabriel! My name is Roger, I live in Taubaté/SP Brasil - It would be a big pleasure change experiences with you. Let me know if there is anything I can assist you with. I bought a laser a few years ago 2.4 mw, unfortunately it already died and I'm so excited to get a new one but as you...

Thank you guys!! You all are awesome!! I really appreciate every attention with these points. I'm intend to find someone travelling to US or Europe to bring in hands to me. That will be the easiest mode to get a new one. Oh God!! :yabbem: hakzaw1 Thanks for your explaining these differences...

Hello dears, Is my first time here in the group, I'm from Brazil and I would like your help with my laser bought from Sci-Fi lasers (501B 2.4mw) 3/4 years ago. Recently I loaned it to my uncle and I can imagine he reversed the batteries and my laser died. Now, when I put the batteries and turn...
