The dual 4 foot, 18 watt 5000K
single ended clear T8 tube
is a good choice

Whether you are changing
out T12s or doing a brand
new install, these 18 watt
tubes work well.

If you have existing T12
and you want to upgrade
to LEDs; you can reuse
these fixtures as the LEDs
will fit into them.

120 volt AC is applied only
to the one end of the tubes.

For dual tubes, on the power
end you require four conductor
tomb stones, to bridge the
power to both tubes.

On the far end you can use
the existing tombstones,
as there is no power there
and they are only used to
support the tubes.


LEDs use less energy.

LEDs turn on in cold

LEDs instantly turn
on bright.

lighting is 4000 to
5000 lumens.

5000 being daylight,
4000 being a softer light.
