FAQ
-
Will this fit my fixture?
If your existing tube is a G5-base T5 tube around 549mm, this is a direct swap.
-
Does this need a starter?
On conventional ballast fittings, yes; on electronic ballast, no separate starter is needed.
-
How does this compare to the 24W HO tube of the same length?
Both share the 549mm length and G5 base, but this 14W HE tube prioritises efficiency over raw output — the 24W HO tube gives noticeably more light from the same length.
-
Which colour temperature should I choose?
840 (Cool White) for offices, 865 (Daylight) for task-focused retail and workshop areas.
