A dropper simply is a small tube with a air-filled bulb at the top. You squeeze the bulb at the top and whatever substance the tube is submerged in, it will be pulled up into the tube. After that, you lightly squeeze the bulb again to release the substance in the tube out.
some uses of light energy are Light energy is used in photosynthesis for plants because plants need light to grow. Light Energy can be used in producing electricity and it also be used for generating heat.

A fluorescent bulb
A light bulb that uses a filament is also known as an incandescent light bulb.
I have a 2001 celica and it uses a 10watt type E bulb.
flouescnet is a type of light bulb that uses less energy
a 2003 Chevy silverado taillight bulb uses a 3157
2002 model uses the 3057
An electric light bulb converts electrical energy into thermal energy which is in the form of radiated light and heat. For example, the " easy bake oven" uses a light bulb to cook the food.
That depends on the type of bulb AND on it's power usage. An old incandescent bulb of 100 watts uses about an amp, a 60 watt uses about a half amp. But a florescent bulb putting out the same light would consume about half the current, and a LED bulb would use less than half that.
Like The Light BULB :P
Light+Heat
More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.
