Comparative wattage of an LED lamp with a halogen bulb

When comparing the wattage between an LED lamp and a halogen bulb, it is important to bear in mind that LED lamps and halogen bulbs differ in their energy efficiency. LED lamps typically consume less energy for the same light output compared to halogen lamps. This means that a lower wattage LED lamp can produce the same or more light than a higher wattage halogen lamp.

For a rough comparison between an LED lamp and a halogen lamp in terms of light output (luminous flux in lumens), the following approximate values can be used:

• An LED lamp with a wattage of about 5-9 watts can have a luminous flux comparable to a halogen bulb with a wattage of 40 watts.
• An LED lamp with a wattage of approximately 9-13 watts can have a luminous flux comparable to a 60 watt halogen bulb.
• An LED lamp with a wattage of approximately 13-18 watts can have a luminous flux comparable to a halogen bulb of 75-100 watts.

However, these values may vary depending on specific lamp models and technological improvements. When purchasing an LED lamp, it is always advisable to check the exact technical data, including the luminous flux in lumens, to get a more accurate idea of how it compares to a particular halogen bulb in terms of your lighting needs.

To accurately compare the wattage of an LED lamp with a halogen bulb, you need to take into account the actual lighting parameters such as lumens, luminous flux, colour temperature and lifetime. In general, however, it can be said that an LED lamp with the same light output as a halogen bulb will consume less energy (lower consumption in watts) and have a better luminous efficacy.
