Panasonic 20,000 Ansi projectors (PT-DZ21K2) are equipped with a multi-lamp system that offers some interesting features and is worth considering when choosing a projector of this category for rental.
Let's look at some:
The use of 4 UHP (Ultra High Pressure) lamps is less demanding in terms of electrical absorption, thus allowing the Panasonic PT-DZ21K2 to have smaller dimensions and less noise compared to other machines of the same class. In fact, the required power supply is a simple 16 Amperes.

Like almost all professional projectors, this machine also offers the possibility to modulate light emission by partializing the use of lamps. But in this case, the PT-DZ21K2's multi-lamp system offers several options, including the ability to turn off lamps one by one.
Panasonic provides a table in this regard, which helps us estimate the projector's brightness under various possible operating conditions.
| Lamps | Lumens (Brightness) |
| Quad | 20.000 |
| Triple | 15.000 |
| Dual | 10.000 |
