Appendix A:

Fluorescent Or Incandescent?

There are numerous advantages to using the kind of fluorescent lighting provided by the PowerBrite PB9 and PowerBrite Pro7 over the incandescent lighting provided by competing rack light products.

Here are the main points to consider when making your purchase:

Fluorescent bulbs generate almost no heat at all; incandescent bulbs can generate large amounts of heat.

Fluorescent bulbs last approximately 50% longer than incandescent ones, with a typical life of 3,000 hours (as opposed to incandescent lights, which rarely last more than about 2,000 hours). There are also “long-life” versions of fluorescent bulbs available which operate for even longer periods.

Fluorescent bulbs are brighter than incandescent ones and they deliver much greater light dispersion. This is due to their longer tube length, which imparts an increased diffusion pattern.

The quality of fluorescent light is similar to daylight, while incandescent lights impart an artificial glow. There are also a wide variety of fluorescent bulb types readily available from most hardware stores, including “soft glow” and colored bulbs which can impart distinctive lighting effects.

Fluorescent lighting systems require no dimmers, which are notorious for adding noise. Because of the lack of a dimmer and the heavy silicon steel shielding employed by the internal ballast transformer (which reduces hum by 20 dB), the PowerBrite delivers noise performance similar to that of an incandescent system.

Taking your rack on the road? Fluorescent bulbs travel better than incandescent ones because the bulb is suspended by both ends of the lamp. In addition, the fluorescent filament is robust and is used only to start the bulb and is then switched off (unlike an incandescent filament, which is much more delicate and must oper- ate continuously).

Samson PBPRO7, PS9, PB9 owner manual Appendix a Fluorescent Or Incandescent?

PS9, PB9, PBPRO7 specifications

The Samson PBPRO series comprises three distinguished models: PBPRO7, PB9, and PS9. These power distribution units are engineered to provide robust performance and exceptional reliability, essential for both live sound applications and studio environments.

The PBPRO7 is well-known for its versatility, featuring seven outlets strategically positioned to accommodate a variety of equipment. It has a heavy-duty metal chassis designed for durability, and a rack-mountable format that fits seamlessly in standard 19-inch racks. The unit's power switch is equipped with a built-in circuit breaker for protection against overloads. Its LED power indicator provides real-time status, ensuring users are never in the dark about their power supply.

The PB9 takes things a step further with nine outlets, catering to those with expansive rig requirements. It boasts the same robust construction as the PBPRO7, maintaining the trend of reliability. The PB9 features a power conditioner that includes a noise filter, which minimizes electrical interference, making it ideal for sensitive audio gear. The unit also incorporates a front-mounted AC socket for easy access, proving advantageous for on-the-fly power adjustments during live performances.

The PS9, on the other hand, is tailored for users seeking even more functionality. It offers nine outlets like the PB9 but includes advanced features such as a digital voltmeter that provides real-time feedback on power quality, allowing users to monitor their equipment’s power status. Additionally, the PS9 features multiple surge protection systems, safeguarding connected devices from unexpected electrical surges and spikes, an essential characteristic for preserving high-value audio equipment.

All models in the Samson PBPRO series integrate superior build quality with thoughtful features aimed at providing safety, reliability, and convenience. They utilize advanced surge suppression technology and EMI/RFI filtering, essential to maintain signal integrity and protect against noise interference in audio setups.

In summary, whether it’s the compact design of the PBPRO7, the increased capacity of the PB9, or the sophisticated monitoring capabilities of the PS9, each unit is crafted to handle specific user needs while ensuring top-notch performance and protection in both studio and stage environments.
