Since July 27, 2006 new products available are available on the store these are flashlights led torches without battery: pocket lamps

hi, i just did some comparative tests between:
HQ LED lamp with crank and high capacity
a shaking lamp (big model from Conrad)
a flat bulb lamp

the HQ LED lamp with crank and high capacity lights with 1 beam much wider than its 2 "competitors".
In position 1 led its brightness is not sufficient to erase the 2 others.
In position 3 LEDs the light is equivalent.
In 5 leds it erases the others. (Leds diameter 10mm, not seen on other lamps)

The duration of lighting and largely above the lamp to shake
The flat lamp consuming a lot of its brightness drops quite quickly.

As a handyman I have already made LED lamps and I was quite critical on all those of the trade that I had in my hands (7 in all), I find that rather well designed, adjustable projector, 2 positions to put it down.

Finally very satisfied (except for the noise of the crank, but it is the same for all the lamps of this type)

Thank you for this little comparative test ... and yes, on the eco-store we pay attention to quality ...

Do you have a photo of the other 2 lamps?

ps: 10mm the LEDs? Aren't they 5mm LEDs?

not 5 but 10mm, the only ones I had already seen, it was on Ebay, an Italian seller it seems to me.

I just checked and visibly (impossible to measure because under the optics) it's rather 8mm but hey I quibble the ...

On the other hand I think that it is not Leds in themselves but of an optics ("hat" covering the Leds) ... when it is extinct at the bottom we see the LEDs (5mm I would say) ... finally it seems to me.

ps: your flat lamp tears I would say even more she is "Wonderful" hihihihihihi

Yep, but museum pieces are rare and expensive

It's nice to hold out my pole to contradict you

(Yes I know we can rig the caliper so that it displays 10mm )
More seriously, the transmitter is hidden in the magnifying glass,
I am not sure it is different from 1 led 3, 5 8,10 mm.

I had a led lamp to shake, offered by a supplier, it's really tickling to make you laugh, even in rescue. I had it for a long time in the empty pocket of the car, at random until the moment it broke.
I recovered the magnet by cons which is a monster!

I would be rather curious to see this crank lamp

for my daily use I use a Petzl headlamp with 3 LEDs which does me a lot of services, especially for connecting devices in dark places. I sometimes have it all day on my head.

what I like is that the light stays white even at the end of battery life. Recently I have a universal charger, I think I'm going to buy a set of Ni-MH batteries (batteries are very expensive in Belgium because surcharged)

Not hard (at least in pictures

for Ni-MH batteries why the lamp use it, the number of recharges and low 500 I think.

ARGGGGGGG he screwed up his lamp !!!!
Well your caliper is more accurate than my eye

This is what I think too ... see my message above ... What does it matter is the end result that counts!

For information, we deliver in Belgium (we are in Belgium ...)

Recupel only represents 0.10 to 0.30 € on the batteries, it is not so surcharged as that!
But all the better, right? It is a policy that I consider econological .... right?
