Very useful video! Well done! 👍👌👏
It's not working .within2 days led gone. What to do
I mean, it's nice but, 'Amazing life hack'? I am not sure about that.
Interesting Vid, to improve it use a cheap 9V battery holder from aliexpress. These come with a build-in switch. Also the 9V battery, I am surprised that the current did not burn out the LED. The modern Alkaline batteries (say genuine Duracell/Energizer) output 2A continues current. Most modern LED these days say the 3W use 9-12V but only 250mA current. The higher 5W just require more V.
A description of the parts used would be useful
Where I am buy led bulb?
I see…5W…never-mind…sorry
What wattage is that LED?

Thank you Julian for the video.
I think you must use a heat sink otherwise excessive heat generated may cause battery to explode!!!!!!.
