does this led iluminates wide directional or just single directional like other leds?

It has a wide beam. It is not a pinpoint focus. It is very good for park lights on your car. Nice cool white in colour. Good product

It is wide. It works just as good if not better than the factory bulb in my 2002 Dodge Ram.

As the other responses the bulb is wide. Using as map lights in 08 tacoma. Almost too bright rarely use the driverside lamp, I use the passenger side and see everything I need to on the driverside of the truck. Hope this helps.

I only recently purchased the pro led, and can't speak to the regular led, but I was impressed with the pro 2D when I tested it. If you tune the beam too wide, you'll get a black spot in the center, but if you narrow it until the center is bright it is plenty of light! If I purchase another, it will be the pro led based on this one.

The light distribution of this Philips LED 'bulb' is close to that of a traditional incandescent A19 bulb. That means you can use it either face up or face down and it makes very little difference.

As with most led lights you will get a long life out of 1 double A, when you extend the light from wide angle to narrow the beam becomes square not round. Not a problem just different. It is still a stronger beam than my 4 D cell regular mag light....and much easier to carry.

Don't know, sorry, but it does only have one intensity, not variable in my lamp.

Yes, all LED bulbs are sensitive to orientation. If mounted in a ceiling fixture (especially a fully inclosed one), the expected lifetime will be reduced. However, Cree bulbs theoretically have well-designed thermal management, so if you're choosing an LED light to install in a ceiling fixture, this is the one I'd go with.

Nope, but you can just just turn it around - both sides look equally good and then the LED is on the back.

The mount is quadratic, and one can attach the lamp in all four directions, which could be useful for those flashing modes sequentially illuminating the LEDs from right to left (or any of the other directions if mounted accordingly). I actually use it in the horizontal position in a 'right-to-left' setting. Passing cars really keep their distance this way...

They are aimable...the puck with the LED's is on a gimble-mount in the trim bezel so you can pivot the light maybe 20° in one direction and the trim can be rotated so you can point it in any direction. Quite pleased with mine, and I purchased dimmable LED's as well.

No. And it is pretty worthless anyway on most bulbs. It just doesn't work and definitely not on a sideways bulb. Frankly I don't believe the positive reviews.

Hello Light waves, With no spec for lumens or CRI on Amazon, I'm almost as much in the dark (NPI) as you. However, I've had one of these running in a decorative spotlight for a few months, so I can make some comments. The color of the light is much better than a CFL, but not as nice as incandescent or the legendary Philips L-Prize bulb. Comparing it with various Philips and Cree LED bulbs that I'm currently using, I'd say the CRI is probably around 80, certainly no better than that. That's just an eyeball estimate though, YMMV. Brightness is roughly equivalent to a 25-30w incandescent bulb. If you use it in a reflector spotlight (I'm using it in an old boat searchlight - the reason I needed a bulb with a BA15D base) it makes an odd but interesting pattern on the wall because of all those individual LEDs spread over a large area. It doesn't dim very well, even with a PWM dimmer specifically for LED lights. However, after my initial experiments, and given it's modest light output, I never attempt to dim it anymore. You probably already know this, but just in case, be aware that this bulb has a BA15D (both bayonet pins at the same height) base. This means you can put it in the socket backwards and it will not work (I've done this a few times, it didn't destroy the bulb). Many bayonet base LED bulbs on the market use the BAY15D base (pins at different heights), preventing it from being inserted backwards. I have found the descriptions - even on Amazon - to be wrong about the base type occasionally, so always look at the pictures carefully to be sure the base type is what you need.

The light is quite directional - but is also very bright. I would say that the output and spread is more than some may want if another person is trying to sleep next to you in same bed. Very good light- is very strong.

Yes, you can change the direction of each individual light. They are very nice and bright.

The light distribution of this LED bulb is close to omni-directional. Basically if you don't look at the bulb, you can't tell the difference between it and a 60W incandescent bulb.

The blacklight tube will probably put out more light in general, but this Sunlite bulb you can put it in a directional lamp holder like I did, to only have the blacklight pointing in only one direction.

I would assume it emits a sound wave in all directions. It does not appear to be directional.

No, the LEDs are only on one side of the light bar; however, the reflector is such that it does provide some degree of peripheral lighting.
