FAQ

• Will this fit my fixture?
  If your existing tube is a G5-base T5 tube around 1449mm, 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 28W HE tube?
  This 35W tube is longer (1449mm vs 1149mm) and brighter — check your fitting's length before switching between the two.
• Is 4000K suitable for a warm-toned office?
  4000K Cool White gives a neutral, business-like tone; for a warmer, cosier feel choose an 830 (3000K) tube instead.
