Halogen bulb and arch lamps
Arch lamps and LED
LED and tungsten lamps
Which of these statement is TRUE
Halogen bulbs have a shorter lifespan compared to tungsten lamps
Tungsten lamps typically produce a whiter and brighter light
Halogen bulbs produce a warmer, yellowish light
Halogen bulbs produce more light for the same amount of energy
Why are arc lamps and LEDs used in specialized microscopes?
Arc lamps provide high-intensity illumination and a broad range of colours
Arc lamps provide stable light output over time when properly maintained
LEDs have a long operational life, highly energy-efficient, emit little heat
LEDs can be engineered to emit light at specific wavelengths
