- Led chips
About led chips, there are a lot of led manufacturers, such as Cree, Epistar, Osram, Philips, Bridgelux, etc. The led chip of each brand comes with different power. It contains 1w, 3w, 5w, 10w and other power. Of course, the cost of high power LED chips will also be increased accordingly. The led chipset of each power is applied to different power led products, which are used for different application fields. Well, you may ask how we know what brand is the best. Okey, as the manufacturers above are all the world's leading LED suppliers, it seems like there is no the best, just better. So when you are going to buy a off road led light bar or work light, please trustingly choose these big brands. You might complain about my light bar is bad to use. Maybe it isn't the cause of LED chips, just the reason else. I put some clear images about the led chips of different brands in here for reference.

- Flood, spot and combo beam
Then talk about the details of the beam pattern. As you know, optional beam pattern contains flood beam, spot beam and combo beam. Each lighting effect of them is not the same. More specifically, the flood beam pattern comes with larger irradiation range and the light intensity in the center of the radiation is relatively weak. So the effective length of the beam is not very far. on the contrary, the spot beam pattern comes with smaller irradiation range, which the light is concentrated in. The light intensity is much higher and the effective length of the spot beam is much more farther. And the combo beam pattern is the combination of flood beam and spot beam. Usually, for the combo beam, the flood beam is on the both sides, and the spot beam is in the middle. It is great when you want versatility. The picture below will give you a clear understanding of them.
For the different series of lightbar, the beam spread of flood and spot is different also. Often, it is 90º and 8º. But the principle is the same. For example, ordinary light bar's pattern is like this:
3D lens light bar's beam pattern is like this:
And 4D lens light bar's beam pattern is like below:
- Straight and curved
Finally, I will say the difference between straight light bar and curved light bar. Certainly, it is not the difference of quality. It just depends on your needs. Because of the different shape, installing position also is different. If you want to install it on the head of the car, the curved light bars is difficult. If you prefer to like curved lights bars, you can install it on the roof rack or the top of the windshield. It all depends you. I show some real pictures of lightbar installed on the cars to you.
