    What ho one and all,

    Recently bought some replacement GU10 bulbs off an eBay seller, specifically GU10 / 6w / 55lms with a listed beam angle of 120 degrees.

    On fitting, they appear OK with one page one exception; I intended to buy 3000k but mistakenly bought 6000k.

    I have been searching eBay again for the same make (Lohas) and can only find 3000k in dimmable. I don't need dimmable but is there any reason dimmable LED bulbs should not be fitted to a non-dimming circuit?

    Apart from the extra cost, no.

    Thanks. More or less what I thought, but what do I know?

    Somehow, I made a mistake and the Lohas lamps that arrived were 6000k. Have now been replaced with 3000k non-dim, 6w, apparently COB with 120 degree coverage.

    Very pleased; kitchen is brighter and the coverage does not give so many shadow areas, particularly when reading the paper.
