Is a godd illuminator is bigger better?

This is somehow surprising that manufacturers place huge emphasis in the power consumption, stating with a machine is 50, 100 or 400 Watts, while in reality it has little bearing on the complete performance of the illuminator. Within the lighting industry, the performance of a lamp is measured in a number of methods, depending upon the comparison standards. The received data regarding a lamp's virtues are, generally, light output and efficiency, although the single most significant element is the burner size.

Efficiency, found in Lm/W, states the amount of light that a lamp creates for each unit of energy utilized. Is very low on incandescent lamps, where mainly of the energy is transformed in heat and extremely high in fluorescent and several types of discharge lamps, like low-pressure sodium. Unluckily, neither of these last lamps can be used sensibly along with fiber optics. The quantity of light that a lamp makes is a helpful piece of information while we try to light up a warehouse or an office table but useless while used to project and concentrate light on a given point. Whenever the screen of the illuminator or the fiber common end. The actual amount and directionality of light reaching the screen, containing little to do with the power consumption of the machine, which is the only measure of performance in an illuminator. Several lamps, specially the latest arrivals, consist of much improved light outputs, better precision and beam control. Paradoxically a final generation 50W-halogen lamp with a dychroic reflector puts more light inside a fiber than a 75W lamp with outdated technology and a similar construction.
