Product Information

If the light bulb is the type that has pins, there may be a third letter to indicate how many pins it has. An LED bulb is a low-wattage light bulb that gives off light using light-emitting diodes. This device emits light when electricity passes through it. Money-saving: they're more expensive to buy, but they can pay for themselves in energy savings over their lifetime. And their smart functionality can help to reduce electricity usage. For example, lights can automatically be dimmed in the evening or can be combined with smart motion sensors, so lights are turned off when no one is in a room.

To replace a 60W incandescent bulb in a living room, you'll need a 60 watt LED equivalent bulb of around 806lm, and its power will be 10W. Or, if the incandescent bulb is 100W, the equivalent LED bulb will be 1525lm and 18W. Modern, energy-saving bulbs use a lot less power to produce the same light. So, now brightness is measured in lumens (shown as lm). The higher the number of lumens, the brighter the light. The brightest light bulb can be 1525lm or more, while the dimmest is around 200lm. Very energy efficient: they're energy-efficient because they use LED technology, using up to 75% less energy than traditional incandescent bulbs.And when looking at the amount of energy they use per year in kilowatts, it's clear to see how their energy savings compare. For example, based on using 20 bulbs for 4 hours per day, in a year, incandescent bulbs would use 1752KW, halogen bulbs would use 1226KW, CFL bulbs would use 438KW and LED bulbs would use 292KW.

In the past, old incandescent bulbs displayed their brightness measured in watts. So, a 100W bulb would be brighter than a 60W bulb. But wattage is only a measure of the bulb’s power consumption, not brightness.E27 – an Edison screw, 27mm in diameter. Used in standard overhead light fittings (also referred to as an ES). Convenient: they can be controlled remotely through a smartphone or by voice command through a smart speaker. This is very convenient because the user doesn’t even have to leave their seat to dim the lights or switch them off. The number of spotlights needed for a room depends on the room’s size. As a guide, you will need one spotlight for every 1m2. Place spotlights approximately 0.5m away from the walls and leave a gap of 1m between each light. Very energy efficient: they’re the most energy-efficient type of light bulb available, using up to 90% less energy than traditional incandescent bulbs and 80% less than halogen bulbs. G4 – a multi-pin (or bi-pin) base with two pins 4mm apart. This is a small and compact bulb used in decorative light fittings.
