British Electric Lamps5 Watt 74mm 3000k Warm White Long Neck GU10 LED (50w)

Unfair to leave a negative review so I won't, but just one note of caution with these - they won't fit a GU10 / L1 fitting. If you don't know the difference, a GU10 / l1 fitting has small pin in the centre between the slots that fits into a hole in the centre of the lamp. These don't have the hole so just won't fit. Frustrating and my understanding is that these were made just a few companies to stop halogen lamps being used in the fittings. I'd advise you to check before you order....to be fair, there's nothing in the description to say L1 but it's a new one on me.

I was really impressed with this bulb compared to other similar bulbs of this kind I own. The others I have installed seem to take an age to reach their full brightness whereas this one seemed instant. Will definitely be buying more when required.

The cheapest version of this light I could find, arrived in good time.Lighting, brightness as described

Used in ceiling lighting in a flat, made to meet fire regulations. Fits fine and works well. Light level just right.

It's is just as described on Amazon. No nasty surprise. It arrived in the said timeframe
