- PL-T 2 pin built the starter in the lamp and works with a conventional gear.
- PL-T 4 is pin makes use of an electronic ballast, possibly dimmable provided that the correct ballast is applied. Other wattages of this type PL-T lamp are not interchangeable. The PL-T lamps have 6 parallel bars!
In difficult to reach places you could choose to use the PL-T (2 or 4 pin) Xtra variant. Lifespan is about twice as high but the purchase also. So if you takes a lot of time or cost as a platform for recovering this can be a godsend
