  • How are LED bulbs compared?

    LEDguide.com aims to provide objective and reliabale information about LED lighting. Based on your choices in the wizard we select the LED bulbs that are suitable to replace your old bulb. We compare the required light output, base, color and beam angle of the LED bulbs in our database. For each LED bulb we calculate how much you will save over a peridod of 5 years. In our calculations we assume that an average bulb is 'on' for 4 hours a day. We also assume an average price of 12 cents per KWh. The savings are scalable; if the bulb is on for 8 hours a day, than the savings will be double.

  • Why are LED bulbs so expensive?

    LED's exist since 1962, but the application of LED's in general lighting is relative new. LED's with a high light output require complex fabrication processes. This explains the higher price for high-power LED bulbs.

  • My bulb has a different shape or base than the choices in the wizard.

    Possibly there aren't any LED alternatives for your bulb available. We are dependant on the bulbs offered by manfacturers and online stores. We regularly add new LED bulbs to our database.

  • No LED bulbs are found when I complete the wizard.

    Some bulbs are still difficult to replace by LED, especially the dimmable and high-power versions. If possible, please adjust your search by selecting a lower power or different color.

  • Which color should I choose: warm, neutral or cool white?

    This depends on your appliaction and personal preference. Warm white light is comparable to that of traditional incandescent and halogen light bulbs. Neutral white is similar to that of fluorescent tubes, while cool white has a slight blueish color. In general, cool white LED bulbs are the most efficient, and warm white the least.

Calculation

The Savings Calculator gives an estimate of the savings you can make. This estimate is based on the average energy consumption of the old bulb and the led replacement bulb. The purchase price of both bulbs is not included in the calculation.

The estimate gives a good indication for replacement of incandescent or halogen bulbs. In general, fluorescent tubes are more efficient, so the savings will be less. For more acurate results we advise you to use our bulb wizard. In the search results you will find a calculation per specific LED bulb. This way you can find the LED bulb that will save you the most in the long term.
