Lamps are light sources which you can use in renders to add more interesting effects and tell a story with your image. You can add lamps by pressing the L key on your keyboard or clicking the light-bulb symbol on the left sidebar. There are four different types of lamps you can use; these all provide different types of lighting to your scene. Once you have added a lamp you can control its properties, like the colour of the light it emits and its strength, from the object panel on the right. Mecabricks lamps work in a fairly similar way to Blender lamps, and there are a lot of good Youtube tutorials explaining how you can use them effectively to enhance your render. You can also use them with other features like volumetric lighting and some of the compositing functions to improve your lighting even more. Hopefully this helped you, if you have more questions please post them here.

@XForce198 Ok thank you... I'll see if I can get it working.
