The only notable difference between the Gadsden and the other lights was the built in LED and although they were more expensive this is the light I chose, I was very disappointed to find out 4 weeks later on delivery that the lights did not have built in LED light and indeed had some loose bulbs supplied with them. There was no identification saying the lights were Gadsden so I assume I have been sent the wrong less expensive lights which I didn’t ask for with no explanation
