I would like see if anyone can lead me in the right direction with my continuing issue with my Dereelight DBS v.2. Below is a timeline from when I received the light from Alan and the troubleshooting steps taken to resolve my issue.
1. Early July I ordered an received my DBS w/3SD pill within a week from Dereelight. At the same time I ordered 3 AW 18650s with charger from Lighthound.
2. Charged the batteries and pulled them off the charger when the light turned green, measured voltage was 4.17-4.19 on all 3 cells.
3. Inserted a battery, powered on the light and after a minute I noticed flickering in all 3 modes. The flickering in HI was so bad, it was like a strobe light and then it would automatically step down to MED . I tried all 3 cells with the same problem. The light was un-useable.
4. I contacted Alan while I was at the beach via my Blackberry outlining the problem and he advised me that a new pill will be on the way and when I returned from the beach, there it was in the mail.
5. I installed the new pill, made sure all cells were fully topped off with the same voltage as stated above. The light seem to work and I contacted Alan and thanked him for his great customer service.
6. A few days later, the problem returned with the new pill
7. I cleaned all contact surfaces with Deox-It from suggestions from some CPF members and reassembled the light. Issue not resolved.
8. I had to contact Alan again to advise him the problem was still present. Alan sent one of his newest 3SD pills and I received it in 1 1/2 weeks. I noticed the new pill didn't have a spring and I asked him about it. He said it was OK.
9. The newest 3SD was installed and when powered on, it would just flash and cut right off. Contacted Alan again and he did say there was a "Bug" in the pill and they had to correct it and when done he will send me another pill.
10. I received the new reprogrammed pill, (this time it had the spring on) along with 2 new switches, and installed it with my fully charged AWs and right off the light came on for a few seconds and the cut off. I had to power it on about 5 times before the light stayed on. Everything seem to be working for a few days until the light started again with cutting off. This was all in HI mode but in Med and Low the light works flawlessly. BTW, when this started happening I checked the voltage of the cells and they were 3.8 - 4.05 and only had been run for a total of about 10 minutes.
11. I put one of my older pills back in and it works in all 3 modes but it has the bad flickering in HI then switches to MED mode.
Now its Sept 23rd, So I ask before contacting Alan again, is it possible that I may have bad Cells? I mean I have tried 3 different switches, 4 different pills, cleaned and lubed the light and still I have a light that cannot be used. Is there any test I can do to test the cells besides checking the voltage? I really love this light, had a DBS v.1 which worked flawlessly and sold here to a member.
I would love to hear some suggestion that may resolve my issue before I contact Alan.
And BTW, I would like everyone to know that Alan has been great at working with me to resolve this issue. A+ to his customer service.
Thanks for listening.
