Great but (Score: 0) by Anonymous Coward on 2016-04-22 04:48 (#1BCH5) We have a long way to go. It is an improvement that one light in the circuit doesn't blow the rest. That one socket can be replaced without affecting the others. The power config isn't good. Turning the light switch off doesn't actually turn off the power. Which can lead to current running through you if you change a bulb with the lightswitch off. That did not hurt, but it wasn't good. Then we have the problem of cost: 1 power cord per light is an upfront cost that can be borne, but the cost of replacing the power packs every couple of years adds up. I remember buying cheap ass $1 light bulbs for years and replacing them without hassle. Going through putting out the whole socket and buying a new transforming for every light in the house is starting to seriously piss me off. The way they churn through bulbs is a concern. The cost of the bulbs is a concern at what? $5 to $25 a bulb? Geez. That hurts. This room has 8 of them in the ceiling. Start multiplying. Yes, it is an improvement over halogen which quite frankly was a secondary heater in the house. There are still improvements to be made. One of them is not using springs with so much tension that they rip through the ceiling plasterboard when the socket is pulled down.
