Lights. CREE XML XM-L T6 / U2 etc Thread

[tincaman]

A good find, cheers.

I have just taken a punt on the above. The cut-off looks v good and the foreground illumination is wide and bright. The trade off appears to be a serious lack of throw. I can't imagine it's anywhere near 1200 lumens, but with a Cree XM-L it will have punch as long as its driven reasonably hard. The pulse mode looks good for lit urban situations.

@tincaman how are you finding it? Will it light up the road 30-40 metres ahead on full power? Have you had any probs with the battery pack failing? What's the run time like on high and medium? Sorry for all the questions!

If it's any good, I might buy two and carry a spare battery pack.

Will report back when I've tested it.

Just done a runtime test:

On High mode
Ran for 95 mins and the red leds started flashing,
After another 10 minutes it switched to Low,
After another 5 mins I aborted because it was visibly dimmer.

Initial votage 4.1v, final voltage 2.8v

The 2.8v is around the point where I would expect any protection circuit to activate, however as it was so dim I wasn't happy to allow it to go any further
So it looks good for 100 minutes on High, pretty good I thought for a 2 cell battery pack

Hello to all of the electronics buffs on here.

I have one of the solar storm lights mounted on the handlebar (where else) and the battery pack in its pouch fixed to the handlebar stem. the issue I have is that it seems to interfere with my wireless decathlon count 8 computer that is mounted on the handlebar stem. I wrap the excess light cables around the stem also.

can anyone let me into a secret way of preventing such interference? it would be appreciated.

many thanks in advance.

This is very common with wireless computers, you need to keep them apart, try the computer on one side and the light on the other side but mounted under the bars

Charge every 3 months for optimum care.

That said some say every Month, others say don't fully charge, but don't allow them to drop below 40%..

Rule of thump, Keep out of sunlight and extreme temps. Don't let them go flat. Personally I'll drop them in a charger every 3 months.

That said they are a consumable, at best you'll get 3 years out of them.

I just popped a spare set I've had lying in the garage for the last 6 months on charge and they fully charged in about 10 minutes. That would make me think they hold their charge pretty well and maybe there is no point worrying too much about storage? Could be I guess that they are knackered in my case, but they are only 6 months old, so no reason to suspect that.

 

[Lanzecki]

Quite possibly. You wont know if you've caused any damage until they fail. I.E. if they fail next week.

But yes, everything I said was the official line. I view them as consumables. They get binned regularly here

Someone remind me what/where the bottle cage fitting batteries are? I think one in particular had a battery level indicator, any clues welcome

Sorry to resurrect this thread, but does anyone know if something like this is any good?

That's what i run. Bloody cheap that!

 

[Mark1978]

Yeah, cheap. However, I do worry about the quality of the battery pack for that price. Might as well buy a few at that price though

 

[Mark1978]

We shall find out in a month or so. I've ordered quite a bit from AE in the past and not had to pay any duty yet. Sellers tend to put "gift" on the package which helps somewhat.

Just bought another couple of these from Amazon ( shipping from China ) . £12.60 for the two, one of old pair failed last winter so back ups required. As the OP has said these are consumables as the quality is just not there but who cares at 6 quid each nearly. However I`ve also found that a spare battery pack I bought a while back for another project will fit and run a Magicshine rear light which is a bonus, so will be purchasing one of those in the near future.

How did you get on? Is the battery pack any good?

Well it's flipping bright, thats for sure, although i haven't used it on the bike at all yet as i've not been out in really dark conditions. Battery pack seems ok but havent had to charge it so i dont know if it's going to explode/melt through the floor. Have used it for a couple of hours as a headtorch while doing some work in the loft and it was real useful.

I terms of delivery, took just under 3 weeks with no import duty. Ive been ordering quite a bit in from china and not had to pay duty on anything yet.

replying to my own post here, both torches arrived, one was faulty on arrival replacement sent which was not any good at all. They then refused to send another and offered me £2.50 comp for the hassle, however full refund been given now. Going to eat my words now and buy somehting more substantial.
