A yellow color will be less likely to attract outdoor insects than will a white bulb. At just 3.6 inches long this light bulb is smaller than a conventional incandescent light bulb. Other enhancements include quickstart technology so the bulb comes to full brightness faster, self-balancing amalgam technology to allow the bulb to generate less heat and offer consistent performance in a greater range of applications, and lead-free glass which will help provide better lumen maintenance over the bulb's life. Of course, the energy savings is important too. This 9 watt bulb will deliver 550 lumens of light, making it a suitable replacement for a 35 to 40 watt incandescent bug light.
Note that this bulb is not suitable for use in enclosed fixtures, emergency exit lights, in outdoor locations where it would be exposed to the elements, or in conjunction with dimmers or photocells.
