Not well protected
This product works well and is a doddle to install. However, I’ve only given it 3 stars because of the packaging. It is not well protected. The first one I ordered came smashed to smithereens. The second one was okay, but very vulnerable. If you don’t know the exact name of the bulb, it’s not going to come up on your search either. Wider search parameters are needed. The actual bulb works well, it lights up my bathroom fine, and the colour is okay. It does the job.
