The NiCad power source provides two hours of continuous light at 45,000 candlepower, requiring only two hours of charge.
While the total luminous output of luminaires is adequate for computation of luminous efficacy, evaluating luminous performance requires consideration of spectral power distribution (SPD) and candlepower distribution (CPD) as well.
Scott attached the excellent 5,000 candlepower MicroStar flashlight from TacStar to the front of his trigger guard.
OSRAM SYLVANIA ULTRA HO LED PAR38 lamps are designed to replace integrated 24-W PAR metal halide lamps, featuring the industry's highest center beam candlepower of 26,000 candela at 15 watts, and the highest efficacy at 70 lumens per watt.
Or is the main issue purely the candlepower and duration of daylight as it strikes the eye, regardless of its path or filtering?
If lamps do not persist and self-illuminated, large surfaces become the norm, lumens and center beam candlepower will be out and candelas per square meter will be in.
Have we gotten into a somewhat similar narrow mind-set when it comes to lighting by being obsessed with quantitative values of lumens and candlepower, while ignoring all the qualitative values required for optimal seeing and working conditions?
Along the way, Brilliant even delves into the development of a candle derived from the head of the sperm whale called "Spermaceti" that was used in the first scientific light experiments and would become the standard for measuring luminous intensity--one candlepower.
She carefully compares color rendition, end-on candlepower, beam distribution, spill light and physical characteristics of different LEDs.
In accent lighting, end-on candlepower and beam spread is very important.
The picture is further complicated by the fact that for reflector lamps, such as MR16s and PAR38s, total light output is much less important than beam angle and center-beam candlepower. Yet many directional LED replacement lamps fall far short of their incandescent counterparts in that regard.
The only aspect of perception that concerns the DOE is the "source." As a consequence, we're flooded with start-up companies that manufacture LEDs and who make outrageous claims of light output and life ratings and neglect items such as lumen depreciation, color degradation, color matching and especially peak candlepower for so-called LED "accent" lamps.
