I would like to know if anyone who has changed to leds has had any problem with them getting dimmer over time. I have put some into a fitting in the house and found that they got very hot and the light fadded out to near nothing over about a month.
Do the ones in the van get very hot?

Bobrovin, I've had mine in place (on the B/T) for three years now and still as bright as the day I put them in , and I haven't noticed them getting hot.
I shall give them the touch test next time we go camping.
I haven't been everywhere but it's on my list.

LED lights do drop off in performance over time and the operational hours versus lux output data can be looked up if you have enough information. However with the varying quality coming out of China it's a bit of a lucky dip these days. Also same brand can vary in performance due to where they source it from. Generally if you go to a reputable supplier they should be able to advise you accordingly.

Hi Bob
The LEDs you put in at home, I'm guessing that they are in those small downlights (that use to be halogen) if so, just check the socket (MR16) as they are only a very small contact point and can heat up/burn.(especially with/after the halogen )

The ones on boards/cards, SMD (surface mounted diode) should not even get warm. The SMDs in my van just lay on the light diffuser.

They will slowly (years) lose light intensity.

Cheers Ken

These were the waterproof strips of 5050 with the tape on the back to stick on. They get so hot you can not touch them and after a short time turned brown with heat.

For the house I first bought cheap Chinese ones and they were very weak. Then I bought expensive Philips ones and they are great.
I changed all my lights in the van to LED strips and they are working fine.
