The Comparison Of Light Bulbs’ Price And Properties
 Růžičková, Veronika
My project deals with bulbs as a type of artificial lightning. It follows up on comparison of incandescent, LED, CFL and halogen bulbs in several aspects: illuminance and luminosity, luminous efficiency, quotient of illuminance and power input, light cone’s shape, speed of stabilisation into full power, the electricity loss and most importantly the price of their usage. Luminosity of three different colors of LED 6W bulbs (of same distributor and type) was added as a bonus.
