Re: Dragon Lasers Spartan 447nm 1 Watt Portable Laser Un-Boxing Video Hi Spartan X, Sorry to hear the beam expander doesn't work too well with the laser. I haven't even been able to remove my front cap. How hard was it to remove yours? Was a fair amount of effort required? I believe...

From what denodan said the beam comparison between the Spartan and the arctic don't sound all that different. I would expect this as neither laser uses correction optics and probably use the same diode. There are bound to be some slight differences diode to diode that happen due to the...

Well Im not sure if I have this right but it seems very good on the "y" axis. At the aperture I measured 1mm. At a distance of 5 metres i measured 3mm. Giving a divergence of 0.399mRad

That amount of batteries should be just enough to power this laser for about an hour :D. Joking aside. I did some divergence measurements today on the wide axis of the beam. At apperture the beam on the wide axis is 3mm thick. At a distance of 5 metres the wide axis of the beam is now 2...

I didn't think the divergence was that bad on this laser given that the diode outputs a bar. Dont forget those beam dot shots are taken at over 20 feet and the camera is zoomed in on them so you can see the beam and any artifacts, that bar is an inch long at that distance. Even 20 foot away I...

Hi Xfly, I found the LiFePo4 batteries and the charger in the UK on a website setup for electronic cigarettes. Tenergy LiFePO4 Charger and Batteries - Cloud 9 Vaping I am unsure if they ship to Europe but if you contact them I'm sure they will answer that question for you. The batteries are...

Hi kcorbhv, Unfortunately I can't comment on the 400mW version as I don't have it, but from what I have heard the beam on it has been corrected so that it looks more like a round (circular) dot that you get with most other laser pointers. Because this laser has had its beam corrected to be...

Apex, Please be careful here. There were two types of Tenergy batteries I reviewed. The 3.2v 750mah LiFePo4s which were rated best and the 3.0v LiCo 900mah Tenergys that came in worst due to their poor voltage regulators. Can you confirm which ones you got coming? If they are indeed the 3.0V...

Hi again everyone, I have updated my original post to include battery testing with this laser. Enjoy LaserLight

Hi apex007, Over the last two days I have been doing a lot of research into CR123 batteries. I have discovered there are alsorts of different types. There are: Primary Lithium Cells rated at 3.0V Li-Ion Rechargeable cells rated at 3.7V LiCo Rechargeable cells that are 3.7v volts but have a...

It is odd, but I cant help but wonder if its something to do with the batteries given my previous issues with CR123 cells that weren't up to the job. I wonder if its because they are adapting to the high curent drain and then stabilise? I think the CR123s I have are right on the limit of being...

Hi Everyone, Thanks for your kind words. First of all @ DJNY I finally manged to time how long it takes the body of the spartan to get warm at 3 minutes 30seconds it is warm to the touch around where the diode and driver sit. Then at 6 minutes the whole length of the host is warm to the...

Hi Dr Sid, Unfortunately no it is not focusable. I am hoping Dragon Lasers will bring out a compatible beam expander to fit this laser which will enable us to be able to do this. In the mean time I am using a magnifying lens to good effect. I have some more positive news on the batteries. I...

Sorry DJNY, I didnt forget you. Basically I've got battery issues. It seems the batteries I have at the moment are cheap and not upto providing the power this laser needs. Following prototype's suggestion in the other thread I have some tenergy 900mahs on order. I will do this test as soon as...

No problem, sorry it wasn't bloom as such, I am lacking in a tripod and my hands arent steady enough with the camera which was causing the dot to blur. I went and borrowed a steadyshot camera to snap those with.
