I write about practical planning questions for commercial LED lighting. My articles cover parking lot lighting standards and electrical load calculations for LED systems. I aim to help readers connect a lighting goal with the checks that follow, from site requirements and fixture choice to the power assumptions behind a proposed installation.
Choose a 0-10V Dimmer That Matches Your LED Drivers
Updated October 2026 An adjustable 0-10 volt dimmer alters a compatible LED driver’s output through a separate low-voltage control signal. Choose it by the driver’s interface, current requirement, and switching load. The lowest slider position may leave the lights on:…
What Are LED Lights? How a Semiconductor Becomes a Lamp
LED lights use light-emitting diodes: small semiconductor devices that convert electrical energy into light. When asking what are LED lights, start with the difference between the tiny emitter and the complete lamp. The emitter makes light, while the driver, optics…
What Is a T8 Tube? Sizes, Bases and Fluorescent vs LED
T8 is a sizing designation for a lamp of a tubular shape with a nominal diameter of 1 inch. This designation doesn’t describe the length, brightness, or voltage of the lamp. A properly fitted replacement in the socket may still…
Why Is My LED Light Bulb Flickering? Find the Cause First
Updated October 2026 LED light bulb flickering is a repeated change in a lamp’s brightness. Common causes of flickering may include an incompatible dimmer, a lamp or driver problem, and an unstable electrical connection or supply. First identify which lights…
Types of Light Bulbs: Complete Guide to LED, Incandescent, Halogen, CFL Shapes & Bases
Light Globe Types: LED, Incandescent, Halogen & CFL Guide Choosing the right light globe types cuts lighting electricity use by 80% to 85% while matching three core specs: internal lamp technology, ANSI glass diameter, and IEC socket base code. Modern…
Electrical Wire Color Codes: Standard AC, Three-Phase, DC Power, and Regional Wiring Identification
Colour Code for Wires: NEC, IEC & 3-Phase (2026) Technical Review: Reviewed by the electrical engineering and luminaire compliance team at Zhongshan Guangqi Lighting Co., Ltd. (Last verified: October 2026). In North America, per NFPA 70, black, red, and blue…
Pool Light Voltage: Match the Supply, Transformer and Cable Run
Updated October 2026 An incorrect replacement at the wrong pool light voltage can result in a fixture that’s unusable and yet another site visit. The building supply number is only the beginning. A low-voltage lighting system can result in a…
How Many Pool Lights Do I Need for My Pool Layout?
Updated October 2026 How many pool lights do I need? First determine the zone of the pool that each light must reach. The pool shape, finish and viewing direction, in addition to the output of the fixtures being considered must…
Pathway Lighting Spacing: A Practical Layout Method for Commercial Landscapes
The spacing of lights in a walking route is known as pathway lighting spacing. The distance between fixtures is determined during commercial landscape design by analyzing the selected fixture’s photometry, path geometry and project criteria. Buying lights first and dividing…
Landscape Lighting Voltage Drop: Calculate the Loss and Find the Fault
Landscape lighting voltage drop refers to the loss of voltage along a loaded cable and its connections. A transformer may have spare capacity while the last path light on a lighting circuit receives too little voltage. Before approving a replacement,…
