An apparatus that is configured to be installed with a predetermined maximum wattage output wherein the maximum wattage output can be selected by the installer. The light fixture includes a housing and an adjustable resistor. A light source is electrically to the adjustable resistor. And the adjustable resistor is associated with the housing.
1. A light fixture comprising:
a housing configured to receive a light;
a driver disposed within the housing, said driver including an input configured to connect to a power source and an output configured to provide power to the light; and
an adjustable wattage limiter disposed on or in said housing, said wattage limiter being electrically connected to the driver and configured to set a maximum output power provided by the driver,
wherein the driver and the wattage limiter are configured to provide power to the light and to vary the power, in response to a dimming input from a dimming controller, between a minimum output power and the maximum output power set by the wattage limiter.
2. The light fixture of claim 1 , wherein the wattage limiter is enclosed in an interior of the housing.
3. The light fixture of claim 1 , wherein the wattage limiter is an adjustable resistor.
4. The light fixture of claim 1 , wherein the wattage limiter is a trimpot.
5. The light fixture of claim 1 , wherein the light fixture includes an indicator to indicate the maximum output power of the light fixture set by the wattage limiter.
6. The light fixture of claim 1 , wherein the light fixture includes an indicator to indicate a maximum lumen output corresponding to the maximum output power of the light fixture set by the wattage limiter.
7. The light fixture of claim 1 , wherein the driver is configured to receive the dimming input directly from the wattage limiter, which is connected between the driver and the dimming controller.
8. The light fixture of claim 1 , wherein the minimum output power is zero.
9. The light fixture of claim 1 , wherein the dimming input is a 0-10V control input or a Pulse Width Modulation (PWM) control input.
10. A light circuit comprising:
a light fixture including a housing configured to receive a light;
a driver disposed within the housing, said driver including an input configured to connect to a power source and an output configured to provide power to the light;
an adjustable wattage limiter disposed on or in said housing, said wattage limiter being electrically connected to the driver and configured to control the maximum output power level provided by the driver; and
a dimming controller connected between the driver and the power source for providing a variable control signal to the driver to vary the output power of the driver between a minimum output power and the maximum output power set by the wattage limiter.
11. The light circuit of claim 10 , wherein the wattage limiter is enclosed in an interior of the housing.
12. The light circuit of claim 10 , wherein the wattage limiter is an adjustable resistor.
13. The light circuit of claim 10 , wherein the wattage limiter is a trimpot.
14. The light circuit of claim 10 , wherein the light fixture includes an indicator to indicate the maximum output power of the light fixture set by the wattage limiter.
15. The light circuit of claim 10 , wherein the light fixture includes an indicator to indicate a maximum lumen output corresponding to the maximum output power of the light fixture set by the wattage limiter.
16. The light circuit of claim 10 , wherein the wattage limiter is connected between the dimming controller and the driver, and wherein the dimming controller is configured to operate in conjunction with the wattage limiter after the maximum output power is set by the wattage limiter, to vary the power to the light between the minimum output power and the maximum output power.
17. The light circuit of claim 10 , wherein the minimum output power is zero.
18. The light circuit of claim 10 , wherein the dimming controller is included in a switch box that also includes an AC to DC transformer.
19. A light fixture comprising:
a driver disposed within the fixture, said driver including an input configured to connect to a power source and an output configured to provide power to a light; and
an adjustable wattage limiter electrically connected to the driver and configured to set a maximum output power provided by the driver,
wherein the driver and the wattage limiter are configured to provide power to the light and to vary the power, in response to a dimming input from a dimming controller, between a minimum output power and the maximum output power set by the wattage limiter.
20. The light fixture of claim 19 , wherein the light fixture includes an indicator to indicate the maximum output power of the light fixture set by the wattage limiter and a maximum lumen output corresponding to the maximum output power.
