If you are considering purchasing LED lamps, there are many things you need to know before you go ahead. LED lamps offer a range of advantages, and are known for their long lives and energy-saving potential. However, dimming LED lamps is not always easy.
Read on to find out more about getting the most of today’s LED lamps.
Why buy LED lamps?
LED lamps can offer 50,000 hours of use if they are engineered correctly according to Futronix.com. You may have seen LED lamps referred to as ‘Solid State Lighting’. This is because they are manufactured from solid materials. Another key benefit of using LED lamps is that they light instantaneously, so you don’t need to wait for a warm-up period to elapse. They can output up to 135 lumens per watt and aren’t affected by cold temperatures. You can also move the bulbs to direct light where you want it.
Check that your lamps are dimmable
One thing you really do need to be aware of is the fact that not all LED lamps can be dimmed. You must check that the lamp is actually dimmable before you make a purchase, so look at the packaging before you proceed. Even if the packaging does state that a lamp is dimmable, this doesn’t always mean that the performance will be fantastic. Some lamps are more efficient at dimming than others. Poor quality lamps are more likely to offer unstable performance and won’t dim as smoothly as superior products.
