Ye ole light bulb in the hall has been flickering over the past few days and it’s finally fizzled out for good. R.I.P dear friend. Oh but hey, why not pick up one of those LED bulbs everyone’s been raving about to replace it? GREAT IDEA! Here’s a quick article to beef up your LED know how before you hit the shops.
Think in Lumens
‘Watts’ is typically what you look for when choosing how bright you want your lightbulb to be, but with LEDs, Lumens are the way to go. You’ll look at Watts to figure out how much energy is being used to light it up. You’ll find that incandescent bulbs can draw up to give times as many watts for the same amount of lumens that LEDs of the equivalent brightness can bring.
What colour should I choose?
LEDs have a truly impressive colour range – everything from electric blue to neon pink to funky purple. But not many would fancy those psychedelic colours in their home, preferring to opt for something more comforting.
Warm whites and soft whites will produce a yellow hue, while bright whites are whiter (closer to daylight).
Light colour is measured in Kelvins. The lower the number, the warmer (ie the yellower). A typical incandescent ranges from between 2,700 to 3,500 Kelvins.
How much should I pay?
Thanks to increasing demand and breakthroughs in technology, LED’s are quite a bit cheaper than they used to be. That said, they still aren’t as cheap as incandescent bulbs. But it’s usually a worthwhile investment that pays itself back in a few short months – they last longer and can cut up to 90% off your lighting bill.
Can they be dimmed?
Most LED’s aren’t compatible with traditional dimming switches, and may hum, flicker or buzz when hooked up to a dimmer. You may need to switch to a compatible dimming switch, or change your choice of LED.
Can they be directly fixed to my existing light sockets?
Although LEDs don’t produce much heat relatively to incandescent bulbs, they still do generate a bit of it. The generated heat is pulled by a heat sink and dissipated into the air. So when considering LEDs you’ll need to make sure the heat is able to be dissipated. If you have enclosed or half enclosed spaces, you may need to get specific LEDs that are approved for recessed or enclosed spaces.
