Frequently asked questions
What is the maximum illumination intensity?
The Welch Allyn Green Series 900 Procedure Light delivers powerful and uniform illumination using six white LEDs, optimized for minor medical procedures.
Key Illumination Specifications
- Maximum Intensity: The light achieves 100,000 lux (9,290 footcandles) when measured at the optimal 24-inch working distance on the High setting.
- Color Temperature: A high color temperature of 5,500 K ensures exceptional clarity and accurate color rendition.
- Working Distance: The effective working range is 24 inches to 40 inches (60.9 cm to 100 cm).
Intensity adjustments, including dimming capabilities, are performed using the touchless controls, a crucial feature for minimizing physical contact and enhancing hygiene in clinical settings.
Does this procedure light have touchless controls?
Yes, the Welch Allyn Green Series 900 Procedure Light features touchless controls for both on/off operation and dimming, helping to reduce the risk of cross-contamination in clinical settings.
Does the light feature an exceptional LED life?
Yes, the Welch Allyn Green Series 900 Procedure Light is engineered for exceptional longevity and cost efficiency. It features a remarkably long 50,000-hour LED life.
This extended lifespan provides significant benefits:
- Maximizes Investment: It eliminates the need for routine bulb replacements.
- Reduces Costs: Coupled with low energy consumption, it significantly lowers the total cost of ownership and ongoing maintenance.
Which mounting options maximize clinical floor space?
The Welch Allyn Green Series 900 is available in three versatile mounting configurations designed to optimize space and mobility in clinical environments:
- Ceiling Mount: This option provides fixed, stable overhead illumination, ensuring the entire work area remains completely unobstructed and maximizing usable floor space.
- Wall Mount: By securing the light directly to a vertical surface, the Wall Mount keeps the floor clear, making it ideal for smaller examination or procedure rooms.
- Mobile Stand: While utilizing a footprint for the base, this configuration offers maximum portability and flexibility, allowing the light to be easily transported and positioned across different rooms as needed.
Does the light use high-quality, bright LEDs?
Yes, the Welch Allyn Green Series 900 is equipped with six high-performance white LEDs engineered to deliver superior, uniform illumination for minor procedures while minimizing heat.
Key benefits and specifications of the LED system include:
- Exceptional Brightness: It delivers up to 100,000 lux of light intensity (at a 24-inch working distance) on the high setting, ensuring clear visibility across the entire procedure area.
- Optimal Color Rendition: The high color temperature of 5,500 K is crucial for accurate tissue observation.
- Long Lifespan & Savings: With an extensive life rating of 50,000 hours, the LEDs eliminate bulb replacement costs and contribute to lower energy consumption, reducing the total cost of ownership.
- Cool Operation: The system is designed with minimal heat dissipation, enhancing patient and clinician comfort.
What is the working distance and spot size range?
The Welch Allyn Green Series 900 Procedure Light is engineered to provide high-quality, uniform illumination optimized for minor procedures. The light maintains excellent spot quality and intensity across its operational area.
Key specifications for the illumination area are:
- Working Distance Range: The optimal operating distance is 24 inches to 40 inches (60.9 cm to 100 cm).
- Spot Size: Within this working distance, the spot size naturally ranges between 9 inches and 11 inches (23 cm to 28 cm).
Notably, the light provides maximum illumination of up to 100,000 lux when used at the closest distance (24 inches) on the high setting.
Which medical facilities use this light?
The Welch Allyn Green Series 900 Procedure Light is ideal for use in clinical settings that require focused, sterile-environment illumination for minor procedures. These include:
- Hospital procedure rooms
- Ambulatory care centers
- Outpatient facilities
- Physician’s offices
Its design emphasizes infection control and extraordinary maneuverability for precise positioning.
What is the procedure light's color temperature?
The Welch Allyn Green Series 900 Procedure Light provides a high color temperature of 5,500 K.
This specific color temperature is designed to deliver superior visibility and maximum clarity, ensuring high-quality, uniform illumination ideal for minor procedures and detailed examinations.
Does the procedure light generate minimal heat?
Yes, the Welch Allyn Green Series 900 Procedure Light is engineered for minimal heat dissipation.
This is achieved through its efficient design and LED technology, which ensures comfort for both the patient and clinician during procedures while maintaining a high color temperature and intensity.
Are disposable sheaths available for this light?
Yes, disposable sheath options are available for the Welch Allyn Green Series 900. These are highly recommended to further mitigate cross-contamination risks and maintain strict sanitation standards in your clinical environment.
