Motion sensitive LED lights

Just put several of these on the boat.

There are cheaper ones with switches, but if I could see the switch I wouldnt need the light.

5 hours doesn't sound very long bulb life!

Or rig a light switch just near the companion, where you can find it before descending into the cave.

Is that because they are battrey powered?

They are battery powered. There are designed for places where you just want a little light for a short period.

They come on for 20 seconds and then go off, which is more than enough time for me to find the can/jar/packet or whatever in a small cupboard, which is exactly what I bought them for. They are hidden from view, but as you put your hand in the cupboard the light comes on. Excellent.

At 20 seconds a go that means I can look in a particular cupboard 900 times before I replace the batteries. Quite reasonable I think.

Who is this companion that I am rigging a light near?

Have used these for a few years, very pleased with them.

Can probably be bought cheaper if you shop around.

If a supplier sells lamps that cause interference then the lamps cannot be CE approved and are simply not fit for purpose. Sent them back and ask for a refund.

You statement above is very sweeping and misleading. I spent 25 years in enforcement, RF type approval and EMC compatibility.

There are limits to which manufacturers have to comply, now self certification, and all transmitting equipment, except amateur radio, have to be correctly labelled with the correct shape and size CE mark.

If I place any make of mobile telephone on a table in a room whilst listening to BBC Radio 2, when the mobile phone receives and incoming call, it will interfere with the broadcast signal. It is not illegal. This is known as the 'By-stander effect' and was so named when mobile phones switched from analogue to digital signals and caused huge problems to people with hearing aids. I was heavily involved in this problem in the 90's and sat on the government committee as a Technical Specialist. Even your microwave oven, when cooking will cause interference, for example, it will stop your WiFi signal as the RFI from the 2.45GHz magnetron is adjacent channel and will spread into the WiFi band 2.2 - 2.4GHz.

By the way, welcome to the YBW forums.

Course he can. Just not in the right direction.
