I bought two of these because I researched them as the cheapest E27 bulbs I could find with a clip. To be honest, they look and feel incredibly cheap. For my purposes it means nothing. I now have two of these lamps for growing seedlings. The fittings work well - exactly as intended. They are easy to understand (configure what goes where, etc.). The length of the cable leaves a lot to be desired, but this is not a problem. I've attached a picture of a setup. They are literally perfect for what I was looking for. I was able to attach them to different things and try out where they fit best. They are strong enough, work as intended and the price couldn't be better. I am happy with the purchase and if I buy more E27 bulbs I will get more of these lights. Buy them: If you are looking for a cost-effective lighting solution. Do not buy: if cosmetics/aesthetics are more important. Their intention is that they are ugly and that cannot be changed. Also, it might seem simple to everyone but me: when you buy it, the metal dome screws onto the base where you insert the light. I struggled with assembly as I saw different methods for this type of device.
