Nik Willmore has come up with Tube Lamp, which engrosses live electrical current, wiring that is appropriate for regular use, and you can dim down like a cozy or clumsy night light.

It is another product of Mad scientist Laboratory that you could try your own, to make a more cost effective version of the tube lamp. All you have to do is follow certain steps to manufacture your homemade Tube Lamp. The project will cost you about $20 depending on the equipment and accessories.

Words of caution. Do not try it on your own, if you don't have some kind of required knowledge of electrical goods, otherwise you may put yourself in danger.
