changing to LED
LED Lighting SA tell us what to look out for when buying LED globes for your home. Why LED? LED lighting offers lower energy usage and longer lamp lifetimes when compared to incandescent lighting. Other advantages include a reduced load on air-conditioning (halogen globes operate around 200°C), lower replacement costs and friendlier waste for recycling – making them the greener choice. What you need to know when buying There are four important aspects to consider when purchasing a LED globe: compatibility with existing drivers, the lumen output, colour temperature of the light and expected lifetime of the product. Compatibility with dimmers should also be taken into consideration when planning a home space. Technical specs
- MR16 globes require a power supply (driver) between mains and the lamp so choosing a product that is compatible will mean they can make the switch to LED without changing the driver.
- Many products on the market don't produce sufficient intensity when compared to conventional halogen globes. Halogen MR16 globes produce 500-700 lumens. Choosing an LED MR16 delivering less than 300lm, depending on the lighting requirement, may not be adequate.
- The warm white colour temperature is the most common choice for most residential homes. Natural white may be used in some areas like kitchens or bathrooms as it's brighter. Cool white, on the other hand, will produce greater light output so make sure that you don’t sacrifice colour for intensity.
- LEDs have greater upfront costs, but they pay for themselves in energy savings and by reducing maintenance. By choosing a quality product with a longer lifetime, you can normally achieve a better return on your investment.
- Compatibility with light dimmers is a very complex aspect of LED lighting, particularly when considering refitting certain globes, so conduct a thorough test of the new product before replacing all your existing lighting.
