Using these bar lights is easy. First, find a suitable location on the exterior surface where you want to mount the lights. Remember, they must be installed by a licenced electrician. The installation instructions sheet in the product box will guide the electrician through the process. Once installed, you can adjust the head of the lights to direct the light where you need it. When it comes to globes, the lamp holder is GU10, but the globe is not included. You can use the recommended GU1001 & GU1002 globes. These lights have an IP44 rating, which means they can handle some dust and water splashes. However, if you live in an area with harsh weather or heavy rainfall, it's best to either protect the lights or use IP65 fittings instead. For maintenance, simply wipe the lights with a dry cloth occasionally to keep them clean. If you encounter any problems within the 2-year warranty period, you can get a replacement.
