When we do an LED lighting installation, we work with you and your organisation to make sure you get the right light fixtures and fittings to suit the needs of your workplace or school. Still not sure? Save Energy 2 Day has lots of experience in tailoring the right light for every situation. Good for cafes and relaxed seating areas.Ĭool white 4000k – crisp, bright and white. Warm white 3000k – still warm but slightly clearer. Used more often in home rather than work settings. LEDs typically come in a choice of three colour temperatures:Įxtra warm 2700k – similar to a classic incandescent light. Classic, incandescent light bulbs are typically around 2,700-3,000k. Conversely, the higher the Kelvin rating, the whiter and bluer the light is. The lower the Kelvin rating, the yellower and warmer the light appears. It’s not just the brightness that makes a difference it’s the warmth or coolness of the light.Ĭolour temperature is measured in kelvin (K) as seen in the chart below. To understand colour temperature, think of the soft, orange glow produced by a fire as compared to the harsh, blue light of day. For instance, if you want an LED bulb equivalent to a 75w standard bulb, look for one at about 1100 lm.Īnother feature of LED bulbs is that they come in different colour temperatures – as illustrated in the picture at the top of this blog. When you’re buying LED lights, take notice of the lumens rather than watts for an accurate measure of brightness. The table below gives an indication of the lumens in standard, incandescent bulbs. Lumens (lm) is a more accurate measure of brightness, and most LED bulbs sold now state the lumens along with wattage (or amount of energy they use). In terms of energy consumption, this clearly provides a significant cost saving. Therefore, when you purchase a 50w bulb, it will consume around 50w of energy.ĭepending on the manufacturer and the technology, a 50w halogen bulb can typically be replaced with a 6 or 7w LED bulb. We are used to buying bulbs according to their watts (W) – however wattage is actually a measure of energy use rather than the brightness. They don’t get hot like traditional bulbs do and, as LEDs are far more efficient at converting electricity into light, they use up to 90% less energy. They use a semi-conductor, or microchip, that emits light when an electrical current passes through it. LEDs lights work completely differently to classic, incandescent lights. How many lumens do you need? What colour temperature should you buy? We explain all below. You can find out how to avoid them below.While LED lights have become much more common in recent years, the terminology is still unfamiliar to many of us.
