Sylvania Linear Double

Sylvania Linear Double halogen light bulbs have a two ended base. This means that at both ends of the bulb, a base is attached. This is called an R7s base. With the filters on the right, you can choose the wattage and light color you desire. We advise you to keep the same specifications as your current light source if you want to keep the same light effect. Make sure you choose the right length! Did you know that there are also LED R7s light sources?

Luminous flux (in lumens) is a measure of the total amount of light a lamp puts out. Wattage is the amount of watt a bulb uses in 1 hour. We've long identified bulbs by their wattage, but that is actually a measure of electricity, not the brightness of a bulb. The amount of light a bulb generates is measured in lumens. An incandescent 60-watt bulb, for example, gives off 750 lumens of light and LED bulbs can deliver the same amount of light using as little as 9 Watt! The amount of Lumen divided by the wattage will show you which lamps are most energy efficient.
