FAQ

• Will this fit my fixture?
  If your existing tube is a G5-base T5 tube around 1149mm, this is a direct swap.
• Does this need a starter?
  On conventional ballast fittings, yes; on electronic ballast, no separate starter is needed.
• How is HE different from HO?
  "HE" (High Efficiency) tubes prioritise lm/W efficiency at moderate output; "HO" (High Output) tubes trade some efficiency for greater brightness in the same physical length — choose HO where more light is the priority.
• Which colour temperature should I choose?
  830 (Warm White) for hospitality, 840 (Cool White) for offices, 865 (Daylight) for task-focused areas.
