Not much difference financially, but there's a huge difference in terms of resource use and pollution.

True but I don't think we are going to stop manufacturing new products if our led lights last for ever. Then we find 10 new things to produce with the saved resorses that we probably could live without.

I was given several of these lights to tag today. Good little light, 0.4A draw.

One came with just a lead as pictured below and the other had a full lead and plug.
However neither of the 2 variants brought had the earth connected internally to the metal housing. I do consider this dangerous given the AC lead is only soldiered onto a small tab on a loose stepdown ac-dc convertor inside the housing.

While this was easy to fix as supplied they are not legal. I am sure everyone can guess the source.

Thanks for the safety review, are you sure about the 0.4 amp @ 240v thats 100 watts not 10w ?

you can get those led flood lights 12volt, 10 watts, for 10$ sent from the "guess from where". i am satisfied with it. i could take it apart and connect with a longer round cable.

Oops had a few beers after work, that current draw was for the 12v version. 0.02A for the 240v model. :oops:

12v model was brought for use in enclosed spaces.

You might be satisfied but it is not really safe unless the lead is fixed to attach the earth internally.

a 12 volt lamp needs to be fixed with an earth?

besides i just mentioned they are able to be opened and connected with a longer wire. i did not mention anything about an existing or not existing earth wire to be connected or not connected
