USAF Dental Evaluation & Consultation Service Return to Equipment Evaluations 52-14 Pelton & Crane Light Fantastic II Dental Operatory Light (Project 96-75) (9/97) The Light Fantastic II Dental Operatory Light is available in a wide variety of delivery configurations including unit-, wall-, and ceiling-mounted (pedestal and track) systems. The light evaluated in this project was provided as a chair-mounted component of the Pelton & Crane S1 Dental Delivery System. This configuration allows the light's functions to be controlled by the S1 System's control panel or the "foot mouse" rheostat. The light's intensity is adjustable in three steps (low, medium, and high) but when configured with the S1 controls, the Light Fantastic II has a variable intensity range from 20% to 100% of maximum. The intensity is purported to include a range of approximately 1500 to 2500 foot candles. The light's 24V/150W quartz-halogen bulb is easy to replace without tools and the light's positioning handles are removable and autoclavable. The Light Fantastic II is available in both 110V and 220V models and is Underwriters Laboratories (UL) listed and International Electrotechnical Commission (IEC) 601-1 certified. Manufacturer: Pelton & Crane (Siemens) PO Box 7800 Charlotte, NC 28241-7800 (800) 659-3212 (704) 523-3212 (704) 523-0002 FAX Suggested Retail Price: $1,925.00 Government Price: $1,155.00 ADVANTAGES: + Excellent quality materials and workmanship. + Access and asepsis is improved with the membrane switches on the doctor's control panel and "foot mouse" rheostat. + Variable intensity (20% to 100%) when supplied as a component of the S1 Dental Delivery System. + UL listed and IEC 601-1 certified. + Excellent illumination pattern. + Correct color temperature. + Self-lubricating pivots and bushings. + Easy focus adjustments. DISADVANTAGES: - Illuminance (intensity) exceeds international and military specifications which may increaseoperator eye strain and fatigue. - Exceeded ISO and military specifications for allowable radiant heat. - On/off switch not labeled. - Lack of positive stops to limit travel of light head and arms could result in patient or operator injury as well as damage to light. SUMMARY AND CONCLUSIONS: The Pelton & Crane Light Fantastic II dental operating light is well made, stable, and performs the functions for which it was intended. The ease of positioning and range of motion of the light head was praised by evaluators as was the intensity and illumination pattern. Although the light met most of the requirements of current standards and specifications for dental lights, there were some deficiencies USAF Dental Evaluation & Consultation Service noted. The light provided adequate illumination for dental procedures even though it was too bright according to International Standard ISO 9680 and military specifications. Exceeding the recommended intensity has been reported in the literature to cause eye strain and fatigue. The light also exceeded ISO and military specifications for allowable radiant heat and two of four evaluators reported negative patient comments regarding the light's heat. All four evaluators rated the light excellent on a scale of poor to excellent and all indicated they would buy the light for their clinic. The Pelton & Crane Light Fantastic II is rated Acceptable for use by the federal dental services.
