Reading lights tend to be marked 5000-6500K these appear much bluer and perceived as brighter. For whiter light – more akin to daylight – good for kitchens and workspaces, bulbs labelled between 3500-4100K would be best.

Incandescent bulbs are around 2700-3000K and produce a yellower warm/soft light, great for creating a relaxed ambiance. Light colour is measured using a temperature scale called Kelvin (K). Choosing the colour temperature of bulbsĬhoosing the right colour is dependent on the atmosphere you’re trying to create within your room, or what the space you are lighting is used for. Bulbs that are nearer to daylight (bluer or cooler in colour) sometimes appear brighter than yellower coloured lights. The colour of light can also affect how bright a light appears, even if the lumens are the same. 60 Watt replacement using only 8.5 Watts (800 lumens) Rated to last 13.7 years based on 3 hours per day use Dimmable and works with most dimmer switches. Incandescent Bulb Wattageĭata sources: American Association of Physics Teachers 1996 and Energy Star 2016 What else can affect brightness perception? However, 60-watt light bulbs are legacy products now being replaced by efficient LED as the leading alternative. An equivalent compact fluorescents (CFL) bulb in light output (lumens) should consume only around 7 watts and LEDs approximately 6 watts. This means that the conversion equation from Watts to. When converting Lumens to Watts for CFLs you will need to divide the Lumens by 60 lm/W, making the conversion equation Amount of Lumens 60 lm/W Watts in a CFL bulb. In fact, a 60-watt LED just may blind you. CFLs (Compact Fluorescent Lamps) generate 60 Lumens per Watt, or 60 lm/W, meaning 500 Lumens will be powered by 8.3 Watts. Wattage to Brightness ComparisonĪ 40 watt incandescent filament bulb produces roughly 460 lumens. An LED that uses 60 watts is in no way comparable to an incandescent bulb that uses 60 watts. Some of the most energy to light efficient LED bulbs are now reaching over 120 lumens in Energy Star tests. On average, an incandescent bulb produces around 14 lumens per watt, compared to 63 lumens for energy saving compact fluorescents (CFL) and 74 for LED bulbs. In this 12 pack, each Warm White A19 LED light bulb gives off 800 Lumens and only consumes 10 Watts of energy compared to 60 Watt incandescent light bulbs. Most of us have a preconception of how bright a 100-watt incandescent bulb is even though this can vary tremendously between soft white and clear glass bulbs. Lumens is an accurate way of measuring the light output of bulbs – brightness is what we perceive, luminance is what we measure. They come in varying technologies, such as Compact Fluorescent (CFL), Halogen and LED and they last much longer – up to 25 years for LEDs!ĭefining the brightness, or light output of bulbs is changing from wattage equivalents to lumens. Nowadays, energy saving bulbs produce far more light, less heat, whilst consuming less energy (Watts). In recent years choosing light bulbs has become far more confusing – you knew roughly what you were getting with a 40, 60 or 100 wattage filament bulb.
