At first glance this looks quite a pleasing light, but its output is very low for the power consumed. This is due to the glass lens being mounted in an aluminium front with a very small hole for the light from the LED to shine through. More for decorative effect than as a useful lightsource.
Again, this came from a China via ebay. http://www.ebay.co.uk/itm/371421993698

    Light Pipe or Fibre Optic from LED to 'diamond' lens would sort output issue 👌

    I actually think it makes a change to find a led light that gives out such a small amount of light. For instance, i have some G4 fittings that i have 5w halogen lamps in, i would love to upgrade to led, but i cannot find any led lamp that will give out the same soft light, all the leds i have tried have been way too bright for the location. I find that problem a lot when i want a nice soft dim light in a table lamp, a few choices with the old incandescent lamps (plus of course you could dim them), but finding led lamps with a similar light output is difficult.

    I'm with a lot of other people, please modify it to get the max light out! 😀

    I love your voice.

    The LED really needs to sit up closer to the light.
    I'm guessing that they just cobbled this design together, not really caring about how efficient it is.

    Looks like the same principle as the deck prism used in sailing ships.

    DIAMONDS !
    I knew that this channel would make it to the top sooner or later.

    Was it just lag or is the connection box maybe drawing 0.2watts?

    Looks like the 230V cables are only singly insulated… hmmmmmmm

    Thanks for sharing

    perhaps the light source is not flush so it bounces around inside the internal chamber and comes out through the hole in a more diffused pattern to illuminate the diamondy thing better.

    Could you put an acrylic glass cylinder in that empty space? That would increase the efficiency, I think. Maybe even some good transparent silicone would do the job.

    I was thinking of sanding down the outer threaded casing, this would allow the LED to protrude into the hole on the lens portion.

    +bigclivedotcom what do you recommend if I wanted to get rid of the CC drivers on 11 of these and replace with a single 12V supply? I could, say, run multiple series chains of 4 (I'm guessing about a 3v drop on each?) but that still leaves me with an odd set of 3 !

    Congratz on hitting the 500 mark on Patreon btw!

    Can you shim beneath the led/pcb to raise it too its highest point??

    You see lights like this very commonly on Ocean Liners or Cruise Ships. More for decor than actual light.
