Tungstenlight vs fluorescent light

Tungsten halogen lamps should be operated between 95% and 105% of their rated current. Within this operating envelope, the relationships between the operating parameters are approximately exponential. Modifying the current to a value different from the rated current changes the other parameters according to the exponents shown in the table below:

Tungsten filament incandescent lamps, particularly tungsten halogen lamps, are often used in illumination systems. Paired with stable, current-controlled power supplies, they provide extremely stable sources. If the current is altered, the filament temperature changes, with a resulting change in filament resistance. Therefore, the voltage change is not linearly related to the current change. Similar nonlinear relationships hold for other characteristics of the lamp, such as power consumed, luminous flux output, efficacy (lumens/watt), color temperature, and lifetime.

What is Light? Light is a form of energy and is part of a broader range of the electromagnetic spectrum. Electrical, radio waves and microwaves to gamma rays form this electromagnetic spectrum. The visible light spectrum is a relatively small portion of this spectrum, between 380 nm and 760 nm. In general, light is often defined as including the infrared and ultraviolet regions too.

Light is necessary for vision. To most of us, it provides a world of visual information. The forms and colors around us are visible only when light from objects around us reaches our eye and triggers the sensation of sight.

The detection of light is a fundamental process and to measure it requires great understanding. A least understood subject in the field of optics, a probable reason is the introduction of new terminology and concepts.

What Can Be Measured? Generally, the total light energy emitted from a source or falling on a surface can be measured. This total energy can cover a portion of the visible spectrum including ultraviolet and infrared energy. Energy at individual wavelength or over a range of wavelength can be measured.

Rays of light reflect, or bounce off, objects just like a ball bounces on the ground. This reflection of light is what enables us to see everything around us.

The science of light measurement is known as photometry and is a subset of the broader field of radiometry – the measurement of radiation outside the visible spectrum.
