The Porcelain bulb is available in three different sizes, with a simple and clean design. We have spent a long time deciding which LED bulbs to sell. We have finally decided on these high quality bulbs from Tala which is also happens to be a British company. There are cheaper bulbs available but we have found that the quality is very patchy with variable lifetimes and inconsistent colour. We therefore recommend the Tala bulbs for use with our lighting.
