With shipping costs, it's almost the same.

Anyway I intend to get the Led lamp


Ben wait a little ... I'm currently prospecting to resell a crank (5 Leds) : Mrgreen:

Hello
I have an LED lamp in dinamo I paid 14,90E a year ago in a DIY store. Today we find it at 7,90E under another brand at a discount store L .... (I do not know if I can say the name : Lol: ) I use it every day for my job.
It works well but you have to turn the crank 2 min to have a good light for 2 min too. The advantage is that before I never had a battery in my lamps while there it is always good.

Well the 5 LEDs I received yesterday I left it on (2 LEDs out of 5, you can choose) all night and this morning it was still not turned off ... although very weak obviously!

So your 2 minute crank, 2 minutes of light ... how to say: either you bought shit (sorry) or your batteries are HS ...

In fact this is precisely what I fear with the crank lamps: the batteries are super sensitive to the method / voltage / charge curve ... and we can not say that the crank is a very gentle method of charging ...

What was autonomy like when it was new yours?

Well, it stays on for a very long time with the LEDs on, but what matters is to see something with it. I have happened to leave the lamp on all night unintentionally. It is given as standard for 180 turns of the crank for 20 to 30 minutes of lighting depending on the number of LEDs lit. 180 turns is long, 2 or 3min turning the crank is long, The battery is given for a life equivalent to 10 years of operation.
After a few minutes, I exaggerate by saying 2 to 3 min I did not count, the lighting is not sufficient (equivalent to a lighter) so it must be recharged. A charger is missing to plug it into the mains from time to time. The crank would only serve as a backup. It seems to me that all the lamps of this style come from the same factory. There is no difference between that at 7 euro and that at 15 euro except the brand.

Battery vs. Condo




by freddau » 23/01/06, 13:58

The hand crank lamp I spoke of lights up pretty well. By cons I have not measured the time taken when the 3 LEDs illuminate at best.

The battery degrades over the years but what about condos ???
They too must degrade, right ??

And last question, what is the pollution induced by Lithium batteries ??? I'm not even talking about lead batteries.

10 years for these batteries ... frankly it would surprise me (note valid for all crank lamps with battery) considering what they take in the "mouth" even a battery charged ideally (continuously) at a level less than 10 years ...

From what you say I am surprised at the quality of mine the light of 3 LEDs weakens very slowly (Benoit should test it on its test bench!) And if I manage to find a wholesaler I will tell you would offer it for sale on econologie :)

For condos their lifespan is bcp + long on the other hand ...

Beware of dynamo + battery lamps .... they are very often delivered with a fully charged battery, so the initial autonomy means nothing.

I had made a comparison on several lamps, and beforehand, I had discharged them all, the performances are not the same after :)

See my Wiki page dedicated to these lamps. (Please do not reproduce this link, it points to a small server behind my adsl modem and my connection is not very fast).

Yeah that's what I thought .... but if we grind enough we charge the battery well to the max (in theory?)

Starting from a discharged battery, we have grossomodo as much light as time spent milling, so the 'max' is hardly reached in a short time : Cheesy:
