Cree Chinese 1600 lumen bike lights. How bright are they?

[Psyclist]

Obviously you can't show how bright with your hands! But just curious if anybody has one. I'm thinking of buying one and would like to know if they're good enough for commuting.
Model name: Cree xml t-6 1600lm.
I did see a thread once on bike lights, but can't find it now.
If anybody has one of these 1600 lumen Chinese lights, or similar please let me know your opinion.
Or, if anybody has taken photos at night to show the strength of the lights, please could you post a photo.

Cheers.

Thanks both of you, but the guy on the ad I found, is saying it's 1600lm.

"Bike bar mount torch Cree 1600lm XM-L T6 led light plus 18650 battery + charger

Hi and welcome to my listing for a Cree T6 Led Torch kit.

As a biker I know how frustrating it is when you have to wait weeks for an item to arrive from China, Hong Kong etc only for it to arrive and be a disappointing waste of money or to have issues when things go wrong.

After a few years of this I decided I could do a better job myself so I've chosen a few items that I feel are good quality and do what you want them to but that I think are still really good value for money.


This little torch is one of my favourite's for a few reasons.

Its really well made, extremely bright and gives a great beam pattern with no hot spot.

I use one handle bar mounted plus a head torch for Mountain biking and just one of these bar mounted for road use.

I run all my lights through two battery cycles before shipping to ensure they are ok :-)


You will receive the following..

Torch

Charger

bar mount

18650 battery (add another for £1.50)

adapaptor to use AAA batteries

1600 lumens is called exaggeration of the facts, the data i put up came from cree's own data sheet for the xml t6 led.

T6 maximum rating is 1000lumens

Don't worry too much about the numbers each ebay seller quotes, they seem to be trying to out do eachother with the size of the lumenfish theyve caught

They're very bright by normal branded light standards, usually with a couple of brightness modes and a silly flashing mode. The build quality tends to be okay if you treat them well, but IMHO you pay for what you get so they dont appreciate tugging on the wires or carrying the battery by its wire for example and you absolutely want a backup light. They're blindingly intense to oncoming traffic too so need to be careful with that, but they are awesome for unlit country lanes and tracks.

I prefer the battery pack ones to the torches, im not sure what the battery life on a single 18650 powering a T6 is though, im just guessing its not great.

On high power about 45 minutes, depending on ambient temp, the quality of the driver and AH of the battery.

the torches are bright enough the throw is not far but for city riding its fine i ran two of them till i got a hv1 and t6 light (like the magicshine)

 

[Psyclist]

Thanks for the replies. It's actually on my local forums buy & sell. I'll probably buy one anyway as it's already in the U.K, and is cheaper to buy.

Have you got a link for this or similar.

I've got one and it am really pleased with it. Plenty bright enough for riding around unlit country lanes at speed. As said above though build quality is suspect - I've not had a problem but you have to treat it reasonably gently, although mine has had an absolute soaking with no issues. I use mine every night for walking the dog. I'm not sure what the burn time is on full beam as I haven't been out for more than about an hour max. When it goes it goes though - no warning, no gradual dimming, so if you are going to be out for a while have a back up. Oh and the charger is a house fire waiting to happen. For £37 it's great value.

Thanks for that. Looks like I'll be buying this weekend

Pretty sure I've had longer,a lot longer
