What is a High Watt Bulb?

How to buy High Watt Bulb


When buying High Watt Bulb, many customers will choose the one with a relatively higher working rate. They think that the higher the power, the higher the brightness. You are affected by the previous incandescent lamps and energy-saving lamps. High Watt Bulb do not have higher power and brightness. The higher it is, their brightness is independent of power.

The brightness of the High Watt Bulb is measured by the luminous intensity, that is, the luminous flux. The greater the luminous flux, the higher the brightness. Therefore, when consumers buy LED lamps, they should pay attention to the axial brightness, not the power. It is also worth noting the difference between the actual light-emitting angle and the effective angle of the High Watt Bulb. The light-emitting angle of the LED light is divided into the effective angle and the actual light-emitting angle. Included angle, the actual light-emitting angle is 2 times the half-value angle for vision.

How to Pick a High Watt Bulb

1. Select the brightness

When choosing a bulb, pay attention to its brightness. You can turn it on to observe the light source it emits to see if there is flickering, whether the brightness can meet your needs, and so on. If it is an LED-type bulb, then you need to use a bulb of about 3 watts per square meter.

2. Power consumption

Generally speaking, energy-saving light bulbs consume far less energy than traditional incandescent light bulbs. When we choose, we can choose according to the light output of the light bulb, instead of the power consumption of the light bulb.


3. Color temperature

Many people think that the light source emitted by the light bulb is white light, but if you observe it with the naked eye, you will find that the color of the light source emitted by different light bulbs is different, and it will change with temperature. For bluish light bulbs, its color temperature is higher, while reddish light bulbs have a lower color temperature and a milder light source, so we'd better choose reddish ones.

4. Lamp head size

Different bulbs will have different sizes of lamp caps. The larger the wattage bulb, the larger the capsize will be.
