When buying an LED bulb to replace an incandescent bulb, it is not easy to make a decision, because the usual 40W or 60W is not on the package. The stated power of 6W or 10W means little to an inexperienced buyer. To make the choice easier, manufacturers often indicate which standard bulb power a particular LED bulb corresponds to. So, for example, a light bulb with a power of 4W produces a light flux corresponding to a 25W incandescent bulb. If the equivalent power is not specified, we can say with great confidence that an LED bulb is at least 6-8 times more economical than an incandescent bulb. You. An LED bulb, for example, 6W will shine no worse than a 40W incandescent bulb.
Color temperature determines the shade of light emitted. The color temperature of an incandescent lamp is 2600-2800 K, which corresponds to a warm white (yellow) glow.
The color temperature of LED bulbs available on the market can be divided into three categories: warm white (2700K – 3000K), neutral white (3500K – 4000K) and cool (5500K – 6000K, cold white).
Bulbs with bases E27, E14, GU10 and G9 connect to 220V voltage. On the other hand, lamps with base MR16, MR11, G4 and AR111 (G53) are low voltage. 12V is used to turn it on.
