Darkfield microscopy
One way to determine the answer is to account for the wattage of all of the luminaires in the lighting system as the wattage of the PoE lighting system. Since there are nine PoE luminaires plus other non-lighting loads (sensors and switches), the wattage of the PoE lighting system is the sum of the wattage of all PoE luminaires excluding the sensors and switches.
LED tape lighting can be installed in length by installers on a project site as determined by the lighting design requirements. LED tape lighting is not like legacy luminaires which are manufactured in a pre-determined dimension per customer order.
Track mounted luminaires as well as rail mounted luminaires are examples of modular lighting systems. The wattage of modular lighting systems that allow the addition or relocation of luminaires without altering the wiring of the systems shall be determined as follows.
The wattage of luminaires with permanently installed or remotely installed ballasts shall be the operating input wattage of the rated lamp/ballast combination.
A Power-over-Ethernet (PoE) lighting system is an emerging lighting technology which provides low-voltage direct current (DC) and communication over ethernet cabling. The direct current powers the luminaires of the system. Most conventional lighting systems use alternating current (AC) to power luminaires.Â
3.  For other modular systems with power supplied by a driver, power supply or transformer, including low-voltage lighting systems, the wattage shall be the maximum rated input wattage of the driver, power supply or transformer as specified by UL 2108 or 8750
Fluorescence microscope
For recessed luminaires with line-voltage medium base sockets, wattage shall not be less than 50 watts per socket, or the rated wattage of the installed JA8 compliant lamps.
Inseparable SSL luminaires are luminaires manufactured with the solid state lighting components which are not readily removed or replaced from the luminaires by the end users.
For meeting the prescriptive or performance requirements for indoor lighting, the wattage of all planned lighting systems, including permanent lighting and portable lighting, shall be determined as follows.
Confocalmicroscopy
The wattage shall be the greater of 30 watts per linear foot of track or plug-in busway; or, the rated wattage of all of the luminaires in the system (where the luminaire wattage is as specified by UL 1574, 1598, 2108, or 8750)
Widefield microscope
What is the wattage of a PoE lighting system that contains a PoE switch, PoE luminaires, occupancy sensors, one daylight sensors, wall switch stations?
A PoE lighting system usually contains three main components â a powered device (PD), ethernet cabling, and power sourcing equipment (PSE) such as ethernet switches. PSE is a general term used for PoE power supply.
Luminaires and light sources emit light and provide illumination to spaces. The Energy Standards include a system of classification to account for the power of luminaires and lighting systems and to use the information for compliance purpose.
Optical microscope
The 2019 Energy Standards allow the wattage of JA8 lamps to be used as the wattage of recessed luminaires. This provides another option for designers, engineers and installers for their compliance use of luminaires with line-voltage lamp holders.Â
This wattage information can be found in the ballast manufacturerâs catalogs based on independent testing lab report as specified in UL 1598.
4.  For power-over-Ethernet lighting system, the wattage shall be the total power rating of the system less any installed non-lighting devices.
Differential interference contrastmicroscopy
Brightfield illumination has been one of the most widely used observation modes in optical microscopy for the past 300 years. The technique is best suited for utilization with fixed, stained specimens or other kinds of samples that naturally absorb significant amounts of visible light. Images produced with brightfield illumination appear dark and/or highly colored against a bright, often light gray or white, background. This digital image gallery explores a variety of stained specimens captured with an Olympus BX51 microscope coupled to a 12-bit QImaging Retiga camera system and a three-color liquid crystal tunable filter.
Lightfield microscopy
2.  For line-voltage track lighting and plug-in busway served by a track lighting protection panel, the wattage shall be the sum of ampere rating of all of the overcurrent protection devices times the branch circuit voltage for the track lighting protection panel; or
Phase contrastmicroscopy
1.  For line-voltage track lighting and plug-in busway served by a track lighting current limiter, the wattage shall be the volt-ampere rating of current limiter as specified by UL 1077
The wattage of inseparable SSL luminaires and SSL luminaires with remote ballasts shall be the maximum rated input wattage of the SSL luminaires.
Another way is to account for the total power rating of the system less any non-lighting devices such as occupancy sensors, sensing devices and switch controls.
The wattage of luminaires with line-voltage lamp holders not containing permanently installed ballast or transformers shall be the maximum rated wattage of the luminaire.
Below is the list of various types of luminaires as described and classified in Section 130.0(c) of the Energy Standards:
The wattage of the luminaire or lighting system shall be the sum of the installed length of the tape lighting times its rated linear power density in W/ft (or the maximum rated input wattage of the driver or power supply providing power to the lighting system).
For all other lighting equipment not addressed by item A through E, the wattage of the lighting equipment shall be the maximum rated wattage of the lighting equipment, or operating input wattage of the system, based on independent testing lab reports as specified by UL1547, 1598, 2108, 8750, or IES LM-79.
