LED savings

The switch to LEDs is relatively straightforward. Most 240 volt traditional, halogen and compact fluorescent bulbs can simply be replaced with LED bulbs. The savings, particularly for the elderly who tend to keep bulbs on for long periods, can be substantial. Changing one 60W bulb in use for 8 hours a day pays for the LED in around one and a half months and saves around £20 a year after that even before considering that an LED has a life span many times that of a incandescent bulb.
What of the pitfalls? Well dimming LEDs is one of them. 50plus believes the technology is still developing and certainly our experiments with dimming have had mixed results. When selecting your 'colour temperature' make sure you choose 'warm white', the traditional light bulb 'colour' unless you'd like something whiter; most people say they don't but do adjust if tested. Some elderly do find the brighter white easier to see with. If you are changing low voltage (12 volt) downlighter halogen bulbs for LEDs you may need to change the 'transformer' as older versions designed for halogen bulbs need a higher current to operate and LEDs don't use it, that's why they save money; considering swapping to 240 volt LEDs or changing transformers. In years to come it's possible that we'll switch to centrally supplied low voltage DC for lighting to get around the need to 'transform' voltage, which is a waste of energy. Having mixed voltages in a house does though raise a raft of technical and safety issues so it won't happen overnight.
Don't confuse LEDs with the CFL (compact fluorescent) bulbs. CFLs are the ones that take time to 'warm up' and have mercury content, something that LEDs, which are based on semiconductors, don't. CFLs are an intermediate technology and will not be around for too much longer.
