FAQ
-
Will this fit my fixture?
If your existing tube is a G13-base T8 tube around 1200mm (4ft), this is a direct swap.
-
Does this need a starter?
On conventional (magnetic) ballast fittings, yes; on electronic ballast, no separate starter is needed.
-
How is this different from the LED SubstiTUBE version?
This is a genuine fluorescent tube that runs on your existing fluorescent ballast unmodified; the SubstiTUBE LED equivalent needs the starter swapped and only runs on magnetic ballast, not electronic — pick based on whether you're staying with fluorescent or converting to LED.
-
Which colour temperature should I choose?
830 for hospitality, 840 for offices, 865 for task-focused workshop and industrial areas.
