Additionally, good interior design should provide adequate lighting. The amount of light needed must be determined in conjunction with the task and visual acuity of the user. As human vision starts deteriorating after age 40, the baby boomers will be driving the need for more efficient lighting as they require increasingly brighter environments.
Another energy saving option is the halogen energy saver. These lamps only offer around a 30% energy saving over incandescents and typically last 2,000-5,000 hours but they do have some advantages over LED and CFLs which are worth considering. In some cases truly retrofit LED can be hard to find and difficulties with the fitting and size of the lamp can occur. The nature of a CFL means its appearance differs from that of an incandescent. Halogen energy savers are however available in a range of shapes including spot bulbs, GLS, candle, aluminium reflector and golf ball making them an easy retrofit replacement for many traditional incandescents and an option worth thinking about particularly if you require decorative on show lighting. For those wishing to retain the traditional shape of their lighting long term, a G9 halogen adaptor is a great way to do so. A G9 halogen capsule is fitted in to the adaptor base (available as SBC, BC, SES, ES) which is in turn screwed into a decorative cover. Once the halogen capsule has expired, the bulb can be unscrewed and only the capsule needs replacing - meaning your decorative lighting remains the same. Another advantage of halogen energy savers is that unlike some LED and CFL they are fully dimmable. Furthermore halogens and CFLs emit light evenly whereas LEDs emit light directionally so make sure to check the beam angle before purchasing to ensure you get the right light output.
The high price of LED has been a significant deterrent for many in recent years. However, as the cost of semi-conductor material falls and companies vie for consumers so LED is becoming a more cost-effective option. In conjunction, improved heat sink technology and reliability is giving customers the confidence to view LED as a long term investment. These days a typical lamp life of 20,000-50,000 is the norm and not an unrealistic manufacturer claim. Some lamps, such as the new Philips Xtreme tubes even last up to a staggering 79,000 hours. It is worth also noting that not all LED are dimmable so check before purchasing if this is something you require.
