"I bought this to go in the security light bought at the same time, as it was not included. The recommended bulb suggested on the listing wasn't available so the helpful staff chose another equivalent for it. They sold be the screw cap one and had to bring it back to replace it with the bayonet cap one. All in all, when it was placed in the light it does a very good job of lighting up my pathway to my door. It's just the right brightness to see with and not a blinding light so to dazzle the neighbours opposite! Value for money too. Happy with this purchase."
