I bought a 20w LED light bulb for £15 after good reviews, more fool me. Ordered at weekend, delivered Thursday, so reasonable service. However, the product was very disappointing. The light is cold, eerie and rather dim. I knew it was cool white when I wanted warm white, but they don't stock them. The poor light may be a result of the design of an LED bulb with the lamp shade. I don't understand why the sides of the bulb are white, but if most light is emitted from the end, it could be blocked by the shade (a pendant uplighter with black in the centre of the bottom) compared to other types of bulb, which give good light. It would be nice to know if this is the case
