Once installed, you can insert E27 bulbs (not included) up to 60W. Remember, don't use globes larger than GLS. This light is only for indoor use. To maintain it, simply dust the weathered grey wood shade regularly. If you have any issues within the 1-year warranty period, you can get a replacement.
