Frequently Asked Questions:
Q1: Why to shift to use 12W high lumen T8 led direct replacement bulbs, not 18W T8 tube, the same lumen output but less costly ?
Because the higher lumen efficacy the t8 tube has, the less energy the tubes would consume, does that make sense to you ?
No ? here is the example for 1 KW*h, for a 18W t8 tube light, how many hours it can lit ? 55.5hrs, correct ? what about 12W tube ? 83.3hrs.
That is to say, if you use to lit 7hrs a day, you can lit 7.9 days for 18W tubes and 11.9 days for 12W, the same electric bill, but you can lit 4 days longer, that is huge difference if there are hundreds of tubes in your facility, and you will see a little high upfront cost but would be returned fast.
Q2: What is the difference between Type A tube and Type A+B tube ?
Type A tube can be called plug and play tube as well, it can be direct replacement T8 T12 fluorescent and compatible with existing ballast. The only difference is that It is only double ended wire, “L” end and “N” end is on each side of the tube, it can not be lit up using any two pins of the 4 pins like Type A+B tube, which can be single ended wire.
