Q & A

Philips 40 Watt T12 fluorescent lamp. ALTO technology uses less mercury for an environmentally safer lamp. Higher wattage for more power and light.

  • Cool white color is very popular for most businesses

  • Far superior color rendering to standard T12. Colors appear brighter and less muted.

  • Perfect for customer areas where visibility and appearance is important

  • Replaces the 34-Watt version F34T12 that is no longer available due to federal energy standards requiring better light quality.

            we were happy to find these as they are getting harder to get and for much less than our local hardware store. they last for many years.
            for free shipping we had to get 3 boxes of 10 but they will be used as we have 6 fixtures that use these bulbs. Bulbs.com had them double packed so no breakage and they were delivered within 1 week as opposed to 3 weeks some place else.

                A:

                This is actually a Philips date code. Where the numbers indicate the year and the letters indicate the month. 3B stands for 2013 and B for February. This is not an important part to replacing your lamp. Please contact Customer Service at 888-455-2800 for further assistance.

            • Q:

              Hello!
              How is a T-12 48" fluorescent tube displaced from its socket
              and how does a person replace a T-12 48" tube ?
              --Is it easy to screw in this lo-ong tube (both ends have to be
              hoisted!) or can it just be plugged in?

              Thank you for your consideration!

                A:

                You should only need to slide the pins into the socket and then twist the bulb in to place to secure it.
