Can you order me a bike as well this light is useless without one.

Hot from me. And whatever you do, DO NOT put the wrong address into the ordering process at 7Dayshop. Once it's in it's INSTANTLY locked in and it can't be changed.
So if the kind person in Manchester that randomly received an unordered front bike light would like to get in touch, that'd make me very happy. :smiley:

If all that is true I can see no basis for calling this a 3W light. Pretty sure too that incandescent filament bulb infra red heat wouldn't get far as some such torches do in fact get quite hot compared to LED.
Went into Poundland yesterday and their front and rear lights seemed pretty respectable as did their £1 bicycle pumps. Probably a good basic source for bicycle accessories on the cheap. Sadly no 20" inner tubes that I was after.

It's not quite that simple. LEDs convert more of their energy to light and less to heat than incandescent bulbs. But incandescents emit that heat as infra-red radiation so it leaves the light unit, whereas LEDs generate heat in the LED die itself. A 3W LED would certainly need reasonable heat sinking to dispose of the generated heat. I built a light with four 3W LEDs in a plastic body, and that needed a computer heatsink and fan to keep it cool.

Some or maybe even most LEDs are quite cool running and more efficient at producing light without heat but I guess some of the new high performance LEDs probably do produce a lot of heat when driven hard but I guess this wouldn't be that type.

Hope all bikers in UK will use it!

Had one of these some time back. The clip is too small for most road bike handlebars. Light ok, but clip will crack and break before the light.

If that was the case maybe there is an easy solder hack that would give you greater brightness but reduced battery life. You might be able to bypass a resistor and put a variable pot in there to give you adjustable brightness.

Maybe, depends on whether it's using a driver circuit or just a resistor to limit the current. If it's just using a resistor then yes - but it probably doesn't have any kind of heatsink for the LED, so if you tried to drive it at 3W it would melt the casing and/or destroy the LED pretty quickly.

It says "3W LED". Which could, if you were generous, mean "An LED emitter which could be driven at up to 3W". Clearly it isn't here.

AAA batteries will last less than an hour
On a 3w led. Not fit for purpose

You mean 5 hours.

They are claiming 20 hours runtime which I assume is with decent alkaline batteries and not the zinc carbon type it probably includes in the package. Single use AAA alkaline gives you up to about 1.2Ah each at 1.5v so 3.6Ah in total for 3 batteries. Divide that by 20 and you only have 180mAh and 3W divided by 1.5V is 2A so this looks to be 0.3W which is 0.2A which would give you up to 20 hours approx. Same situation if the batteries are connected in series to give 4.5V it still has to be 0.3W rather than 3W.
Maybe the 3W rating is equivalent to a 3W incandescent bulb rather than actual power consumption. Seems to be exploitative marketing and you'll probably find the poundland lights give similar output. In fact the Poundland LED bike light uses 4 batteries instead of 3 so could be brighter unless only runtime is improved.
Normal 3W battery lights that consume 3W are quite expensive and not at this price level and require higher capacity batteries typically a large rechargable li-ion battery pack.
Not saying this isn't a deal but the '3W' bit should be ignored.

You can get a good set of bike lights from Home Bargains for around the same price or slightly cheaper. Not sure of their power but they can't be far away from 3W, look quality made as well. :smiley:

7day shop... if you like cheap replica watches or cheap replica parfumes, just give them your e-mail address. They will give it away to such sellers.
I was careful enough to give them an alias which I deleted after 1st spam

Heat added... Just bought for my hard tail MTB that I use to cycle to work. They'll do the trick until mornings/evenings get lighter for visibility. :smirk:

I think these are 200 lumens when using fully charged batteries (not 100% sure buy they look quite similar to one I bought on ebay).
For me (aka: this is my biased opinion), these are ok to use on ok-lit roads, but not bright enough to ride on unlit roads (specially country roads).
