You were attracted by LEDs’ eco-friendliness and cost-efficiency? Looking for a new more durable light bulb? Or just want to learn how the technology works? That’s easy! This article will help you to become a real LED lighting expert or at least to choose LED bulbs wisely.
By basics I mean a crew base. If it doesn’t match a socket on your lamp, the chosen bulb will be useless. There are a lot of different types, but we’ll review the most common ones: E27, E14 and G53.
E27 is the most widespread. Number “27” indicates the screw base diameter in millimeters. So if you don’t see the marking on a bulb’s body or package, you can easily determine the screw base type by measuring it.
E14 is the second most common screw base. Such bulbs are less powerful than those with E27 base and are usually used in compact wall and table luminaries or in chandeliers with multiple lighting elements.
G53 (GX53) is used mainly in LED spotlights – flat bulbs with ceiling fitting. They often go with the appropriately shaped luminaries.
Many of us got used to choosing light bulbs by their wattage: the higher it is the brighter the lamp will shine. But this simple rule is not always applicable to LEDs.
LED-lamps consume much less power than incandescent analogs. Why? Incandescent bulbs spend up to 90% of energy on heating and only 10% on lighting. LEDs are not so wasteful. They heat up just slightly and as a result consume more power “with use”.
LED’s brightness depends on such feature as luminous flux and is measured in Lumens. But if you still prefer to choose bulbs by their power, our small table will help you to select a LED lamp by wattage equivalent.
Note that this table operates with average characteristics and they may differ from manufacturer to manufacturer. For example, Jooby Décor LED bulbs consume 4.2 Watts of energy on emitting 550 lumens of light. That makes them 2 times more efficient than an average LED lamp.
If you’re going to install the bulb into a smooth brightness control luminary, make sure that the chosen model is compatible with dimmers.
Light has its temperature: soft yellow light of incandesced bulbs is "warm". “Cold” is bright white or even bluish light. Warm light helps to create cozy domestic atmosphere. Cold light lamps are usually brighter and, as a result, more common in offices and working spaces.
The color temperature (or CCT) is indicated in Kelvins (units of absolute temperature). Bulbs with CCT between 2600 - 3500К emit warm yellow light. And the lower is this characteristic - the more yellow is the tint. Cold white light has the temperature of 5500 - 6500К and natural daylight effect may be achieved between 4000 - 4500К.
Put it simply, choosing the color temperature of light is just like setting up the water temperature in shower. The right balance of hot and cold makes it pleasant to stay under. The color temperature is able to affect not only our interiors but also our mood.
