            Comments about Philips Lighting Company 42 Watt, 4-Pin Neutral White Long Triple Twin Tube CFL Bulb:

            These bulbs are used in a church fellowship hall environment. They were chosen by the building contractor and have proven to be reliable and energy efficient. Two bulbs in the same fixture burned out after two years of continuous illumination. No problem with the other 40.
