Whether you manage a sprawling commercial property, oversee city planning, or run a business with a parking lot, getting it right matters. In this guide, we're zeroing in on LED street lights and breaking down the choices to help you make informed, efficient, and cost-effective decisions. Ready to brighten up your space with the right lights? Let's illuminate the primary considerations to guide your selection process.

Key Features: Best LED Street Lights

When selecting the best LED street lights for your project, there are several features to consider that differentiate high-quality models from the rest. Here's what to look for to ensure you're getting the most out of your investment:

Luminosity

The luminosity, or brightness, of LED street lights is measured in lumens. High-quality LED street lights offer a high lumen output that provides clear, bright lighting without being overly harsh. This is crucial for enhancing visibility and safety in any illuminated area. Effective luminosity also means better light spread, reducing the number of fixtures needed to light an area, which can further drive down costs.

Energy Consumption

One of the primary benefits of LED street lights is their energy efficiency. The best LED lights consume significantly less energy than traditional lighting solutions like HID or fluorescent systems. It's true that this efficiency results in lower energy bills – but LEDs also reduce your carbon footprint. Look for lights that offer the best lumens-per-watt ratio, ensuring you get the maximum brightness for the least energy used.

Durability

The environment where the street lights will be installed can greatly influence their durability requirements. High-quality LED street lights are built to withstand environmental conditions, such as extreme temperatures, moisture, and dust. They should have a durable housing, usually rated at least IP65, which indicates strong resistance to dust ingress and low-pressure water jets. Additionally, quality LEDs are built to maintain optimal performance over their lifespan, reducing maintenance costs and frequency of changeouts.

Color Temperature

Color temperature is an important factor in setting the right ambiance and functionality for street lighting. Measured in Kelvin (K), color temperatures for street lights typically range from warm yellow light (K) to bright, daylight-like white light (K). The choice depends on the area's requirements. For instance, warmer light might be preferred on residential streets for a cozier feel. At the same time, cooler daylight temperatures are better for commercial zones and main roads for greater visibility and alertness.

Smart Features

Modern LED street lights often come with smart features that enhance functionality and efficiency. These include dimming capabilities, motion sensors, and photocells to save you both time and energy. Such features improve energy efficiency and offer adaptive lighting solutions, adjusting to different conditions and needs automatically, which can further enhance safety and reduce operational costs.

Smart design #1: Aluminum body and passive cooling for better heat management

LED lighting generates much less heat than high pressure sodium (HPS) lighting, but it still generates heat. So the housing of your LED module needs to efficiently manage excess heat. Otherwise the light output of your LEDs will decrease dramatically. There are two choices to keep the LED module cool. Active cooling with water or a fan. Or passive cooling that uses the material of the housing to dissipate the heat from the LEDs. Signify opts for passive cooling because active cooling introduces extra parts to the product that can cause the LED system to fail. For instance, water cooling can leak and has to keep running to avoid algae formation even when lights are off, so it uses more energy.

That’s why we’ve used a cast aluminum body for our LED modules to create a heat sink. It has large cooling vents that promote air flow and make it easy to clean the module. Small vents can collect dust and moisture that lower the module’s cooling capacity and make it difficult to clean. Our large cooling vents let water easily run off during cleaning and reduce pool forming that can produce moisture in the product. The top of the module and all of the cooling vents are rounded to prevent moisture from standing.

The cast aluminum body has been milled to create a completely flat surface. The Metal Core Printed Circuit Board (MCPCB) is attached to that milled surface, but we still fill even the smallest spaces between the milled surface and the MCPCB to optimize the thermal resistance. In fact, the LED toplighting compact module has an IP66 ingress protection rating. This means it can withstand dust and water from coming in. The design of the toplighting compact thus ensures that the grow light delivers very high light output, consistently over time, while being easy to clean.

Smart design #2: Standard connector for easy, cost-saving switch to LED 

The LED toplighting compact is designed with a Wieland connector and adapter that fits existing HPS connectors, so you can easily replace your HPS lighting with our LED lighting, using your existing HPS set-up and trellis. We use standard Wieland connectors because they are a dependable and proven product in the horticulture industry. In fact, 85% of our current HPS installations are also equipped with Wieland connectors. You can replace HPS with our LED lighting as long as the power load of the connection is not higher. For example, W HPS can be replaced by an LED product of max W without any problem. Because the LED module is mounted under the trellis the connector is placed on the side of the housing, allowing you to easily access and mount the cable or a splitter.

An important advantage of our LED toplighting compact is that it does not have an inrush current; this is the instant surge of current drawn by an electrical device when first turned on. That means you do not need to change your breakers when switching to the LED toplighting compact. Many LED products have high inrush currents that can overload a standard breaker, meaning you have to modify your circuit breaker cabinet to use them, which can be very costly. 

Smart design #3: Driver in a separate compartment 

When you turn the LED module on, the air around it warms up. And when you turn it off, the air cools down. You want to do this in a controlled manner, otherwise as the module cools down, moist air will be drawn into the module which can corrode electronic components over time. To prevent this, we’ve placed our driver in a separate compartment and sealed it with a gasket to create an enclosed component. A gore-tex vent on the compartment works just like self-breathing raincoat, allowing air to circulate but preventing moisture from coming in and depositing on the driver. Our drivers are developed in-house and meet the most stringent standards to protect against sulfur and safeguard electronic performance.

Smart design #4: Powder coating provides solid resistance to corrosion and flaking

Our aluminum body has a white powder coating. Why powder coating? Unlike paint which is very sensitive to chemicals, powder coating is applied electrostatically and then cured with heat or UV light making it much more robust. It costs slightly more, but pays for itself in the long run. Your powder-coated LED module resists chemicals used in the greenhouse that can erode paint and cause corrosion. It also looks great and no paint flakes fall off after a few years of use.
