Frequently Asked Questions
- What is Candlepower?
Answer: Candlepower is the “capacity of a searchlight to produce light” and does not change over distance. (Note: See chart at top of page which translates Candlepower into Distance).
- What is Lux?
Answer: Lux is a measurement of the intensity of the searchlight beam at a specific distance, and it changes as the distance increases or decreases.
- What is the difference between a Xenon and Halogen Searchlight?
Answer: Halogen Searchlight uses a lamp with a filament, and requires no separate ballast, whereas a Xenon Lamp has an “arc” between two electrodes, and requires a ballast. Xenon Searchlights service a much greater distance, because the light source is much smaller, and therefore, the beam can be “concentrated” into a much smaller, narrower beam, on demand.
- What is a “Metal Halide” Searchlight?
Answer: This is a searchlight which uses an arc lamp, similar to a xenon arc lamp. However, metal halide lamps have a warm-up cycle, and take from approximately 30 seconds to 1 minute for the beam to come ON. Since C&F makes marine and security searchlights, it is a requirement to have a product which is “instant ON”, therefore, we do not offer this technology.
- Does Carlisle & Finch offer LED Technology?
Answer: LED technology has come a long way in recent years, but it still cannot compete distance-wise, nor economically, with Halogen and Xenon Searchlights. Therefore, C&F has created “LED Hybrid” Searchlights, which combine auxiliary LED Modules with these traditional light sources, to utilize the strength of multiple light technologies on demand, within the same versatile product!
- What is Electric Beam-size Focus?
Answer: Electric Beam-size focus, allows the operator to widen and narrow the beam, by activating an electric switch. Since halogen beams are already sufficiently wide, this feature is not as practical for halogen searchlights, however, xenon searchlights can be narrowed and widened very strategically using this feature. Electric Beam-Size Focus is a standard feature, on xenon searchlights.
- What are the various ways a searchlight can be aimed?
Answer: There are three ways a searchlight can be aimed as follows: Remote Electric Joystick Control, Remote Manual Lever Control or by using a simple handle attached to the back of the searchlight head.
- Can I get a custom color, or other finishes?
Answer: Yes, you can get custom powder coat colors, as well as a polished brass finish, or a chrome finish. Note: In order to provide a custom color, you will have to provide the industry standard paint color (i.e. “RAL” Code), so we can match the powder to the color you desire.
- How can I get parts for an older searchlight?
Answer: Simply send an e-mail to sales@carlislefinch.com, and describe the part you require, and provide the 5-Digit Serial Number of the searchlight, which will be stamped on a nameplate, located on the searchlight head.
