Ive wondered how good these are. Saw one at a carboot new for £5. Do they run on d cell batteries, last 10 minutes and bulbs burn out after 30 minutes?
No.
They don't last as long as 10 minutes.
I bought one because I needed a torch and...a MILLION! Wow! Big number, must buy!
On a full charge, I get full brightness for maybe as long as 30 seconds. It then dims rapidly to a dull glow.
I don't know how long the bulbs would last because the thing is so useless that it doesn't matter.
The wind up torch I bought for a couple of quid somewhere is far more useful because it's much smaller, much lighter and can quickly be charged enough for a minute or so of enough light to be useful in the dark. I have a couple that I use for reading my meters (they're in cupboards and difficult to read without direct light on them) and if there's a power cut or the cut-out trips when a bulb burns out.
