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

I've had mine about 14 months now and recently it's started to sporadically turn itself off whilst I'm riding. Although the wire is a bit tatty now there doesn't seem to be any loose connections. So I'm thinking maybe it could be a battery issue - the light seems to run fine if it's fully charged, anything moderately less and it's temperamental.

The power light has always been on green when it's happened and I've only ever once seen it on anything other than green despite running it for a few hours between charges.

Do the batteries get worse with age/every charge? Anyone else have any similar problems?

Postie just delivered the light, I gave it a quick try before I plugged it in to charge. First off it's super bright! Second off, that flash mode is epilepsy inducing - whoever thought that having it flash that fast should be fired (or forced to look into the light for an extended period of time).

I will post an update once it's charged!

Wow, I pressed the power button to turn it on and held it for three seconds, the light now has a low, medium, high, fast strobe and slow strobe mode - I'm impressed!

I'll have to see if mine has a slow strobe. Thought there was only one type of strobe.


My light had 3 modes and it said in the instruction manual that when the light is off, hold down the power button for 3 seconds and it turns the light into 5 modes. It worked!

Have to try that

Uploading a video now of my light setup, the XML light is on the fifth mode - slow strobe. It's not just the one setting though, it has some different patterns which will help make it stand out I think.

And as for the waterproofing, I wrapped the batter up in a plastic bag and then 'sealed' it with lots of sellotape - I was out with it for an hour in the snow and it's still working, charging now!
