Cree light bar

Types of CREE Light Bar

• Single Row Cree Light Bars

  Single row CREE light bars are made with a single row of LED bulbs. These are made in different sizes that are measured in inches. Single row CREE light bars are designed for low-profile lighting. They are mounted on the top or front of a vehicle. Single-row CREE light bars are known for their sleek and low profile design.

• Dual Row Cree Light Bars

  Dual-row CREE light bars are similar to single-row CREE light bars. The only difference is that they have two rows of LED bulbs instead of one. The top row faces forward and the bottom row faces slightly down. This design helps to create a more even light distribution. Dual-row CREE light bars also produce brighter light than single-row CREE light bars.

• Curved Cree Light Bars

  Curved CREE light bars have a special design that is not straight like the others. Instead, they are bent into a curve. This curved design helps to make the light beam spread out wider. It covers more area in front of the vehicle. This is good for seeing better at night or in bad weather. Some curved CREE light bars have a single row of LEDs, while others have two rows like the dual-row ones.

• Flood Light Bar

  CREE flood light bars are made to give off light that spreads out wide and far. They are not as bright as spot light bars but are great for lighting up a big area. Flood light bars work well for activities like off-road driving, construction, or being in places that are dark. They help make everything visible without being too bright.

• Spot Light Bar

  Spot light bars focus their light into a tight beam that goes very far. They are made to illuminate a specific area that is far away. Spot light bars are perfect for things like racing, off-road driving at high speeds, or any other activity that requires seeing really far ahead.

• Combo Light Bar

  Combo light bars blend the qualities of flood and spot light bars. They have both types of lights in one bar. The flood section lights up the area nearby, while the spot section shines a light on things that are farther away. This gives the best lighting for situations where one needs to see close and far. Combo light bars are useful for off-roading, towing, and any activities done at night.

Specifications and Maintenance of Cree Light Bar

Cree LED light bars are available in various specifications to suit different applications. Here are some common specifications:

• LED Count:

  The number of LEDs in a light bar can vary, with options such as 12, 24, 36, 48, or more LEDs.

• Size:

  Cree LED light bars come in different lengths, typically measured in inches or millimeters. Common lengths include 6-inch (152mm), 10-inch (254mm), 12-inch (305mm), 20-inch (508mm), 30-inch (762mm), and 40-inch (1016mm) or longer.

• Beam Pattern:

  Some models may have a combination of spot and flood beam patterns for versatility.

• Lumen Output:

  The total light output of the light bar, measured in lumens, can vary. Higher lumen values indicate brighter light. Cree LED light bars typically range from a few thousand lumens to tens of thousands of lumens, depending on the size and number of LEDs.

• Color Temperature:

  The color temperature of the LED lights is measured in Kelvin (K). Cree light bars are available in different color temperatures, such as warm white (around 3000K), cool white (around 5000K-6500K), or daylight white (7000K-10000K).

• Voltage:

  Cree LED light bars are designed to operate within a specific voltage range. Common voltage options are 12V, 24V, or 36V. It is important to match the voltage of the light bar to the electrical system of the vehicle or application.

• Waterproof Rating:

  The IP rating indicates the light bar's resistance to water and dust. For example, an IP67 rating means the light bar is completely dust-tight and can be submerged in water up to 1 meter for 30 minutes.

• Material:

  Cree light bars are typically constructed with durable materials such as aluminum or polycarbonate. Aluminum housings offer strength and heat dissipation properties, while polycarbonate lenses provide impact resistance.

• Mounting Options:

  Light bars may include various mounting options such as brackets, bolts, or a mounting cradle for easy installation on a vehicle or other surfaces.

Cree light bars require regular maintenance to ensure optimal performance and longevity. Here are some general maintenance tips:

• Regular Cleaning:

  Dust, dirt, and debris can accumulate on the light bar's surface, affecting its brightness. Clean the light bar regularly using a mild soap solution or automotive cleaner with a soft cloth or sponge. Avoid abrasive materials that may scratch the lens.

• Check Mounting Hardware:

  Periodically inspect the mounting hardware, such as screws, bolts, and brackets, to ensure they are tight and secure. Vibrations from driving on rough roads or off-road environments can loosen the mounting components over time, potentially causing the light bar to become loose or fall off.

• Inspect Electrical Connections:

  Check the electrical connections, such as the power and ground wires, to ensure they are secure and free from corrosion or damage. Clean the connections if necessary and ensure proper tightening to prevent loose connections, which can cause flickering lights or complete light bar failure.

• Inspect for Damage:

  Regularly inspect the light bar for any signs of physical damage, such as cracks in the lens, housing, or mounting components. Replace any damaged parts promptly to maintain optimal performance and prevent further deterioration.

• Check for Moisture Ingress:

  Inspect the light bar for any signs of moisture ingress inside the housing. If moisture is detected, it may indicate a seal failure, and the light bar may need to be disassembled and resealed or replaced.

• Firmware Updates (if applicable):

  Some advanced Cree light bars may have upgradable firmware. Check the manufacturer's website or user manual for any available firmware updates and instructions on how to perform them, if necessary.

By following these maintenance tips, the Cree light bar can provide reliable and bright illumination for extended periods.

How to Choose Cree Light Bar

Choosing the right CREE light bar for specific needs requires careful consideration of several factors. Here are some key points to keep in mind.

• Consider the Purpose: First, think about what the light bar will be used for. Is it for off-road driving, which needs a lot of light, or for on-road use, where a more minor, less bright bar would be enough? Also, consider other uses like marine lighting, motorcycle safety, or truck decoration.
• Brightness and Beam Type: Check the lumen output (brightness) and beam type (spot, flood, or combo) of the light bar. A higher lumen output means brighter light. Spot beams focus the light into a tight area for long reach, while flood beams spread the light over a broader area but don't reach as far.
• Size and Shape: CREE light bars come in different lengths and shapes (straight, curved, etc.). A longer light bar will generally provide more light and a wider beam than a shorter one. A curved light bar can create a more concentrated spot beam than a straight one. Choose a size and shape that fits your vehicle and lighting needs.
• Quality and Durability: Look for a light bar made with high-quality materials like aluminum housing and polycarbonate lens. It should be waterproof (look for an IP67 or IP68 rating) and resistant to dust, dirt, and debris, especially for off-road or marine use. Check the warranty period offered by the manufacturer as an indicator of product quality.
• Installation: Consider how easy it will be to install the light bar on the vehicle. Some come with all the needed mounting hardware and instructions, while others may require additional parts or professional installation. Look for a bar that is easy to install, with clear instructions and all mounting hardware included.
• Price: CREE light bars vary widely in price. Determine a budget and look for a light bar that offers the best quality and features for that price. Remember that a more expensive bar may be a better value in the long run if it lasts longer or is brighter than a cheaper one.
