I got some of these last year and have to say that there ace. I use them a festivals. 1 set of batteries lasted the whole festival. They make perfect lights for inside tents. Glasto is only round the corner. I paid £4.50 last year so I'd get in whilst there this cheap!
Subtle, safe, portable discrete lighting.
3 x times brighter than standard fairy lights
Battery operated so no power sockets required.
Expect very long life from these bulbs up to 100,000 hours
These LED bulbs stay cool and never get hot.
Ideally suited to indoor use. (don't know why, mine got soaked lastyear and are still perfect)
Uses 2 x AA Batteries (not included)
