what means a Spot beam(10 degree)
1472216
spot beam and flood beam, this is about the light shape, spot beam 10 degree, and flood beam 45 degree

i reconmend you to use combo, if you want to put on roof of the car, the beam should be long enough, because you may drive at high spead.

The beam is fixed but has three different modes where you can change the order in which they cycle with the push of the button on the end of the unit. Out of the box the modes in order are: High Lumen, Flashing, Low Lumen

Keith said spot. I think they have to much spread to be spot. They light up a pretty large area despite being mounted about 6' off the ground in my application.

There's 3 different beam. high medium low. Strobe and SOS. Too me I don't think u need it any brighter. We nicknamed it the sun

PAR 20 refers to general shape and dimensions. You also need to check three things: flood or spot; lumens; and color (usually 2700K/warm or 3000K/cooler).

These have a flood beam that I would say is about 90 degrees... the light is very cool in temperature, perfectly diffuse, no hot-spots. This is not a SPOTLIGHT. It is a work light. Doesn't throw very far, but has I wide beam.

It is a spot light, you would not be pleased with the narrow beam. However, if you diffuse it with wax paper or something similar, the beam is much softer and wider.

The beam angle is 38 degrees. (see the following for more details: http://www.feit.com/led-lamps/performance/dimmable/reflector/par38-wp-led)

Doesn't specify the angle but it is a spotlight... I'm using them indoors tho, others are saying it is a flood light outdoors :/

10 yards is the peak brightness. At that distance they hurt your eyes, and traffic hates me which is why I bought them for my motorcycle. I want to be seen! The exact angle I can not determine. it is a very tight pattern that does not spread out until about 45 feet.

It's the width of the light beam. 60 being twice as wide as a 30 degree light. Therefore, 30 is more of a spot light and 60 more of a flood light.

I don't think so, this is better as a reading light as the beam is focused on a spot.

Beam area at focus = 2 cm2.power density at focus = 10 mW/cm2 for continious wavePeak power at focus (typical) = 35 mW/cm2 for pulse wave

It is very bright. You cannot see into it directly. The beam pattern is circular and it is wide enough because the intensity helps to point the beam far to make it wide to about 10 ft.

It should mean the amount of focus or concentration of light that is spotty which would be more the 30 or diffused and broader which would be closer to 60 degrees. You should check the laws in your state for where you can mount these lights. In NY I believe you can use these for off roading or plowing driveways but not on the highway. Anything mounted above your original headlight even the hood may not be used on the highway. Therefore 30 degrees would be less in the eyes of on coming traffic but 60 would be definitely in their eyes. It would look brighter to them but you would see further in the dark with the 30 if that makes any sense?

The bulbs are integrated into the external reflector section. The housing seems to be the most limiting factor. I would guess the beam is limited to about 90 degrees.

Like the previous response, it's between a spot & floodlight. The beam angle is about 30 degrees either side of center and is very bright. In the dark it will clearly light up the house at the west end of my field over 1500 feet away when it is on high. It almost turns night into day. You will not be disappointed.
