There are many types beam pattern for led work driving light and led light bar,while the most popular and widely used is these 4 types: Spot (Long Range), Driving and Spread, Fog, and Flood.
Spot Beam (Long Range): Spot or Long Range lights are able to penetrate deep into the night. KC Long Range Lights produce a tighter, more focused circular beam of light (pencil beam) to see way out ahead toward the horizon even at higher speeds. These lights create an extremely bright, hot center beam pattern. Spot beam lights are typically used for Off Highway, Commercial, Agricultural and Racing applications.
Driving and Spread Beam: Driving lights are designed to supplement your high beam headlights. KC's Driving lights all comply to both SAE and ECE regulations and requirements and are street legal. KC Driving Lights produce a rectangular shaped beam pattern that can reach further and wider than your headlights. Driving lights are very useful to create visibilty near the sides of roadways and out in front of the vehicle. They are great for all around trail riding as well.
Spread beam lights are similar to Driving but tend to be brighter, wider and possibly taller as they are not required to follow specific SAE or ECE safety standards. Spread beam lights are great lights for multi-purpose off-road use.
Fog Beam: Fog lights are intended to be mounted below the headlights and project a beam pattern which is very wide horizontally and narrow vertically usually called a cut-off. This pattern lights up a pathway close to the ground but does not light the airborne particles in the line of sight while driving - this increases the visibility in harder to see conditions. KC Fog beams are very useful in Dust, Fog, Rain and Snow. They also work well as Cornering lights in clear conditions and are optically designed to increase visibility in tandem with your primary headlights.
Flood Beam: Flood beams create a large wide pattern of light that floods an area with an extremely tall vertical and wide horizontal light pattern. These lights are typically used as work lights and back-up lights to see a broader area at shorter distances.
Pls choose the right beam pattern for your application
Trapezoidal Beam:The trapezoidal beam (shown in dotted lines) is an ideal, general-purpose work light designed with a narrower pattern for longer visibility
2. Five things to consider before buying car led lighting
When your halogen car lighting is not enough bright as you want, it's a good time to consider switching to LED.
LEDs have an impressive lifespan (50000hours!) and are very cost-effective.
Now's the right time to switch to LEDs. These bulbs have made significant advances over the last few years, Because there are so many LED varieties, choosing an LED is entirely different from many types. Before you head to the store, find out what you need to know about choosing the right LED bulbs.
Lumens, not watts
Forget what you know about halogen -- your watts are no good here.
When shopping for bulbs, you're probably accustomed to looking for watts, an indication of how bright the bulb will be. The brightness of LEDs, however, is determined a little differently.
Contrary to common belief, wattage isn't an indication of brightness, but a measurement of how much energy the bulb draws. For incandescents, there is an accepted correlation between the watts drawn and the brightness, but for LEDs, watts aren't a great predictor of how bright the bulb will be. (The point, after all, is that they draw less energy.)
For example, an LED bulb with comparable brightness to a 60W incandescent is only 8 to 12 watts.
But don't bother doing the math -- there isn't a uniform way to covert incandescent watts to LED watts. Instead, a different form of measurement should be used: lumens.
The lumen (lm) is the real measurement of brightness provided by a light bulb, and is the number you should look for when shopping for LEDs.
You can always count on halogen providing a warm, yellowish hue. But LEDs come in a wide range of colors

As shown off by the Philips Hue, LED bulbs are capable of displaying an impressive color range, from purple to red, to a spectrum of whites and yellows. For the home, however, you're likely looking for something similar to the light that incandescents produce.
The popular colors available for LEDs are "warm white" or "soft white," and "bright white."
Warm white and soft white will produce a yellow hue, close to incandescents, while bulbs labeled as bright white will produce a whiter light, closer to daylight and similar to what you see in retail stores.
If you want to get technical, light color (color temperature) is measured in kelvins. The lower the number, the warmer (yellower) the light. So, your typical incandescent is somewhere between 2,700 and 3,500K. If that's the color you're going for, look for this range while shopping for LED bulbs.
You'll pay more for an LED bulb
LED bulbs are like hybrid cars: cheaper to operate but pricey upfront.
When switching to LED bulbs, don't expect to save buckets of cash. Instead, think of it as an investment. Luckily, competition has increased and LED bulbs have come down in price (like this $5 LED from Philips), but you should still expect to pay much more than an incandescent.
Bottom line: unless you're replacing many incandescent bulbs in a large house, you won't see significant savings in your electricity bill.
Watch out for non-dimmable LEDs
Because of their circuitry, LEDs are not always compatible with traditional dimming switches. In some cases, the switch must be replaced. Other times, you'll pay a little more for a compatible LED.
Most dimmers, which were likely designed to work with incandescents, work by cutting off the amount of electricity sent to the bulb. The less electricity drawn, the dimmer the light. But with your newly acquired knowledge of LED lingo, you know that there is no direct correlation between LED brightness and energy drawn.
If you'd like your LED to be dimmable, you need to do one of two things: find LED bulbs compatible with traditional dimmers, or replace your current dimming switch with a leading-edge (LED-compatible) dimmer.
When shopping for LEDs, it helps to know what kind of dimming switch you have, but if you don't know (or would rather not go through the trouble), simply search for LED bulbs compatible with standard incandescent dimmers. To make things easier for you, we tested a slew of them to find out which LED bulbs work best with dimmers.
Not all light fixtures should use LEDs
Knowing where it's OK to place an LED will ensure that the bulb won't fizzle ahead of its time.
You probably know that LED bulbs run dramatically cooler than their incandescent cousins, but that doesn't mean they don't produce heat. LED bulbs do get hot, but the heat is pulled away by a heat sink in the base of the bulb. From there, the heat dissipates into the air and the LED bulb stays cool, helping to keep its promise of a very long life.
And therein lies the problem: the bulb needs a way to dissipate the heat. If an LED bulb is placed in an enclosed housing, the heat won't have anywhere to go, sending it right back to the bulb, and sentencing it to a slow and painful death.
Consider where you'd like to place your LED bulbs. If you have fully or semi-enclosed fixtures you need to light up, look for LEDs that are approved for recessed or enclosed spaces.
3.5 steps you should know before buying led work light
A work light is used in a particular job-related situation, such as for automobile mechanics repair, theater technical setup, mining and marine applications. It can also be used for automotive lighting, patrolling, hunting and other moving environments. When you choose a work light, you’d better consider the specifications in terms of your working environment.
To judge if the LED work light you are considering is the best choice for you, there are some features that you can compare.
1) Type (Beam pattern)
The first thing you should notice is the type of light. Consider what type you want, floodlight, flashlight or off-road light. Floodlight is widely used to provide wide-angle lighting for outdoor work in construction sites and other facilities. Flashlight is widely used for emergency lighting and is usually rechargeable. Off-road light is applied to automotive lighting. So choose the type of work lamp according to the purpose of your project. Then you should narrow your choice according to the following features.
2) Size
The size of the device is critical. In certain work situations, the space is limited, so you cannot choose a bulky work light, otherwise you will not have enough space to operate. Of course, when space is sufficient, the lamp size will not be an issue.
The size is from 2inch to 9inch,pls choose the one suitable for your device
3) Power & heat output
If your work needs intense bright light especially in industrial and mining areas, construction sites and so on, you should choose a high-power work lamp. The higher the power is, the higher the intensity is. However, a higher power usually transforms to higher heat generation. If a light emits a lot of heat, the space will be too hot for the device to function properly and people will feel uncomfortable, especially in a narrow room. So you should balance the power and heat output to reach a best combination for your work conditions.
4) Power supply
Most flashlights use dry batteries as power supply. Then you will need to replace the batteries from time to time when they run out of power. Some work lights work on built-in rechargeable batteries. For this type of light, it is be important to know the operating time and the recharging time. In addition, the available chargers might influence your decision, too. A rechargeable work light is often sold with an AC charger or car charger or both.
5) Fixation.
Another vital factor is how the LED work light is kept in position. Work lights come in varieties of designs, including bar light with a hook on one end, hand-held flashlight, floodlight with a handle, lamp on a tripod and a lot more. So find the most convenient method for you to place the work lamp and choose the best fit design and feature accordingly.
There may be other features that you need to consider, such as waterproof grade, slip-resistance, shock-proof, overcharge protection, rotation and so on.
