Omnidirectionality
The bulb features an omnidirectional design, which means it puts light out evenly in all directions. You'll want that downward light if you're ever using it in a bedside reading lamp.

Energy efficiency
Osram's LED draws just 6 watts, making it one of the most efficient 40W replacements you can buy. Like most LEDs, it promises to last for 25,000 hours -- well over 20 years if used for 3 hours a day, on average.

Smaller heat sink
The bulb also features a smaller heat sink than most LEDs. This leaves more room for the bottom hemisphere of the bulb, which is where that downward light comes from.

Dimming performance
Osram's LED is compatible with dimmer switches, though we did detect a small amount of flicker with some switches on low settings, as you can see in this GIF.
