You can choose the model of R7S LED bulb according to the length. For example,our 8W R7S LED 78mm is designed to replace 100w R7S halogen 78mm. Our 12w r7s LED 118mm can replace 150w r7s halogen 118m. You can check the length of your lamp. Then you will know which model to choose.

Here is the Halogen Lights Vs. LED.

Surge Protection Devices (SPDs) are protection devices in electrical installation systems . They can prevent excess voltage appearing at the terminals of sensitive equipment.

Should an overvoltage event occur, the surge protection device diverts the resulting excess current flow to the earth and therefore protects the electrical appliance.

Any electronic equipment can be vulnerable to transient over-voltages, which can be caused by lightning activity or a switching event. This creates a voltage spike increasing the wave’s magnitude to potentially several thousand volts. This could cause instant damage or significantly reduce a piece of equipment’s lifespan.

All our R7S LED lights have SPD. This will ensure the safety when use our LED lighting. Also the SPD will make sure that our R7S LED light can be used more than 50,000 hours.

Yes, It couldn’t be more easily to intall our R7S LED lights. For example, if you want to intall 78mm R7S LED light,you can remove the original R7S halogen lamp. Then you can install the 78mm R7S led light.You don’t need to do other extra work.

You can use dimmber with our R7S led lamp. First, you need to choose our dimmable R7S LED lamp. Then you can use dimmer with our R7S led light. Please remember do not choose the non-dimmable model !

Normally, we offer 2 years warranty for our R7S LED lamp. This is why we are the reliable R7S LED lamp manufacturer. But it does not mean our R7S LED lamp can be used for only two years. In fact, the lifetime of our R7S is about 50,000 which means more than 10 years. For example,one mobile phone can be use for 5-10 years,but the brand can offer only 1 year warranty.

Many customers asked us how do you calculate how many lumens with a certain kelvin. Some R7S LED lamp manufacturers don’t have this answer on their page. In fact, these are two measurements that are not directly related. Kelvin is not a measure of brightness rather it is a measure of color temperature.

If you are looking for brightness, the proper measurement to look for is lumens. In general though, 5000K or cool/daylight white will a appear brighter than 2700K all things being equal but this is due to the higher contrast of such light.
