Bulb Wh

Top Modern light bulbs rating represents the energy consumption of a light bulb, measured in watt-hours (Wh). This rating indicates how much electrical energy the bulb uses when it operates over one hour. Understanding the Wh rating is crucial for consumers aiming to manage energy efficiency and reduce electricity costs.

Modern light bulbs come in various types such as incandescent, LED, and CFL, each with different energy consumption levels reflected by their Wh ratings. For example, traditional incandescent bulbs may consume 60 watts (Wh), while energy-efficient LED bulbs provide the same brightness at just 10 watts (Wh). This difference significantly impacts energy usage over time.

Specifications:

• Power Consumption: Typically ranges from 5 Wh (LED) to 100 Wh (incandescent) depending on bulb type and brightness

• Voltage: Usually 110-240V AC (depending on regional standards)

• Brightness: Measured in lumens; higher lumens require higher Wh but energy-efficient bulbs provide more lumens per Wh

• Lifespan: LED bulbs with low Wh rating can last 15,000 to 25,000 hours, while incandescent bulbs last around 1,000 hours

• Base Types: E26, E27, B22, etc., compatible with standard fixtures

• Color Temperature: Ranges from warm white (2700K) to daylight (6500K)

• Energy Efficiency: LED bulbs with low Wh ratings meet Energy Star standards for energy savings
