Renewable Energy Lights

I recently purchased my first dynamo light. Pretty cool little thing, bought if for a wopper sum of one buckeroo. At where else than the 99cent store :bigsmile: Anyway I remember seeing these back when the century turned, also along side them was the ever so unpopular shake light with the coils in them. Point is that all these free renewable energy source lights hit a peak and dwindled for the most part. There are still new examples popping up but dont really hit the mainstream heavily enough to have the majority of households own these examples.

I would love to have some higher quality renewable lights, whos got em? This thread is for basically anything related to unconventionally powered lights.

Ill start with mine

I had a torch just like TrakTuned’s new purchase. I think that mine cost about £2, somewhere in England.

I think I had got about an hour’s use out of it before the cheap and nasty plastic gears broke :frowning:

LMAO that was too funny :smiley: Those were the good days. I loved that show! Why do I have a feeling that if this episode was on today, there would be a petition against madtv….lol

The shape remind me of the old computer memory device in the early 2000. Looks very handy though. Easy to put in your pockets.

Had one, broke in 5 minutes - plastics innards cant handle normal use.

had one, working just fine until one day slipped from palm seize and cracked.
the light still on though :smiley:

I have some different lights, including a black nightstar which still works and is a nice light. When I got it it was even bright(compared with standard bulb lights).
It is about 0.25m long.

It has a 5mm led and a lens in the front.

I’ve had several. All the ones with Li-Ion crapped out eventually so now I’m down to two, both use capacitors. I have an old Night Star shake and one similar to this:

Thanks for the posts! I love seeing these things and as soon as I find some higher quality ones, I will stock up.

The little dynamo light in my first post is awesome though, seems tough enough to survive hundreds of cranks. I’ve already revved that thing to the moon messing around with it :bigsmile:

Any more?

I have one very small dynamo light since a year which was a advertisement gift with some yoghurt or so.
I have found a similiar light on fasttech last week, mine has just a bit darker plastic and a logo printed on the side…

My Nightstar generation III is the real deal, a permanent flashlight for the apocalypse.

I have the same blue one as in the first picture by trak tuned. In fact I bought half a dozen of them for about a buck each. Put them in cupboards and cars. I have had them about 5 years and all still work perfectly. The light output is not great but in an emergency in total darkness it’s amazing what little light you need to help you out. What I have found is the length of time they hold charge for unused. I have left a charged one in the car for 6 months and still had useable light the next time I used it without charging, for a few minutes anway :slight_smile:

These solar power keyrings seem interesting:

Not sure how these colored ones are but the black solar panel lights have no connection to the panel. Just a battery and a switch, the solar panel is just decoration…

They are crap, solar panel doesnt work, I assume its what Werner said - just decoration!
Ive had orange, bright green one, black ones, with push and side switches, all failed!

Has anyone tried building a dynamo light with higher quality parts instead of cheap plastic?

I was given one identical to this for a birthday or xmas in early to mid 2000s

From memory it was 2 mode, 1 LED or 3. It also had a battery so it would store charge.

I never really used it, it was in a garage when it got flooded and was damaged. It still worked but it wouldn’t hold charge and you had to keep winding it constantly for light.

From memory they were about $30-40 or so in the shops back then.

I also remember my friend had a bike and the light on the front was powered by a wheel that was held against the wheel with some kind of bracket and spring, but I don’t remember if it had a battery pack or not to store the power as well.

Did you get your from Banggood? I saw some disassembly pics[1][2] which led me to think some have a panel connected and others are just dummy decoration (like these that FastTech used to sell).

No, mine were all from Ebay years ago, never bothered to get them again.
