No.
One is chemical energy, the other is electrical energy.
Fluorescent tubes last longer and supply more light per watt of energy consumed than an incandescent bulb.
It is the Incandescent light bulb. Most of the energy are lost as heat
Any form of electrical lighting will produce both light and heat, and with inefficient, incandescent lighting you get a higher proportion of heat rather than light, as compared to other forms of lighting such as fluorescent, or the most efficient, which is LED, which turns almost all of the electric power that it consumes into light, and very little into heat.
A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps. The lamps use a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.
they light up
No. The incandescent bulb uses electrical energy and the light stick uses chemical energy.

Yes, incandescent light is produced directly by heating a filament so hot that it glows, in accordance with cavity radiation laws. The energy to heat the filament comes from the electricity passing through it.
About 2 %.
Heat.
Yes.
Two sources of light energy include the sun and incandescent light bulbs.
An incandescent light bulb would be a prime example.

In an incandescent light bulb, electrical energy is transformed into thermal energy and then into light energy. When electricity flows through the filament of the bulb, it heats up and becomes white-hot, producing thermal energy. This thermal energy then causes the filament to glow and emit light energy.
