Ok. My third post
English is not my native language which may lead to some misunderstanding.
When I said that LFM lights are cheap I mean price only, not construction. I like construction and will definitly buy one more LFM light.
As for customer support - try to contact light-for-me directly and you will get same problems. May be UK office is good.
I bought GoPro video system 1800 lumens from them and had problems with it. Let me show some quotes from my and their emails.
Question: I have XTAR 18650 3400 mA/h accumulators and they fit one of the lights and do not fit other. I had to make hole for battery insertion bigger. I think you should test your lights with more accumulator types.
Answer: We use the above mentioned batteries and the set works perfectly well.
Am I a liar? May be (with only two posts)
Question: If you use protected accumulators then you have minus wire just along accumulator side under thin (in fact very very thin) plastic cover. Body of your light is plus wire trerefore you have plus and minus wires divided by only very thin plastic. If you also have narrow hole for battery you could damage plastic and get shortcut circuit.
Answer: Lights used in the set (as also our backup lights) do not have any electronics built-in. So the light output will slowly get dimmer and dimmer. With hogh quality batteries of capacity 2800-3400mAh you will get around 1,5h full power output and then the light will get darker so you will know that it is time to charge the batteries. Usually you would need to charge the battery at the same time as gopro - this camera usually requires charging every 1h-1,5h. That is why protected batteries are not necessarily required, we only require high quality batteries eg. Samsung ICR or Panasonic NCR 18650B which you charge regularly.
Wrong statement! You must use protected accus when light have no built-in electronics. Otherwise if you forget to charge accus and continue to use lights you will get broken accus, because of properties of LiIon cells.
In my case fixing not fitting accus was easy as I can use lathe.
The main question was about safety in using protected accus and the possibility of shortcut circuits in case of broken isolation. No help from support so I have to invesigate the problem by myself.
And the answer is yes - it's safe. Mistake was in that the side wire is minus wire. Really it's plus wire. So no shortcut can occur.
At this point I was satisfied with LFM lights construction but not with customer support.
Hope this helps to somebody.
these connectors a made like milking attachments for cows ...and they are very vulnerable ( same deal tilly- tec )
