If you look after an office, a warehouse, a car park or a block of shop units, you probably still have T8 fluorescent tubes somewhere. Replacing them with LED is one of the most common lighting upgrades in Singapore, and it is usually a case of swapping like for like, tube for tube. It still goes wrong when people skip one or two checks.
This guide covers what to check, what to buy and how to plan a bulk replacement.
Why now
NEA's energy rules for lamps were extended on 1 April 2024. Since then, T8 and T5 linear lamps of 500 to 1500 mm, both LED and fluorescent, are regulated lamps in Singapore. They must meet minimum energy performance standards, and LED tubes need to reach 100 lumens per watt while fluorescent tubes need 75. They also carry the energy label, with ticks based on efficacy.
In practice, this means any tube you buy should have an NEA registration and the label. A tube that does not is not a bargain. NEA says non-compliant supply is an offence under the Energy Conservation Act.
Check your fittings first
Before you order, walk the site and count. Write down, for each area:
- Tube length: 600mm (2ft) or 1200mm (4ft)
- Number of tubes in each fitting
- Whether the fitting uses an old magnetic ballast, an electronic ballast, or a starter
- Ceiling height and how you will reach the fittings
The ballast check is the one that catches people. LED tubes come in two broad kinds. Some are designed to work with the existing ballast or starter. Others need the starter removed or the fitting rewired so that the mains goes directly to the tube. The product listing will say which. For example, Philips' Contractors Grade LED tube is listed as installing in luminaires operating on a mains power connection. Check each listing for starter and ballast notes before you buy.
If the fitting needs rewiring, that is not a DIY job. Our installers can quote it. For bulk retrofits, we assess the job and the access requirements first, by site visit.
Choosing a tube
Four things matter on a tube listing.
Lumens, not watts. A 4ft tube listed at 32W is not necessarily brighter than one at 18W. Compare lumens. For reference, the Loyal 4ft tube on our site is listed at 3840 lumens for 32W, and the Philips Contractors Grade 4ft tube at 2100 lumens for 18W. They are different products at different prices, so look at what you are paying for.
Colour temperature. 6500K is a cool daylight white, common in stores, workshops and back-of-house. 3000K and 4000K feel warmer. Pick one per area and stick to it, or the floor will look patchy.
CRI. Many tubes are CRI 80. If you inspect or match colours in the space, ask for higher.
Lifetime. The Loyal tube is listed at 25,000 hours. Philips' SmartBright battens are listed at 30,000 hours. Lifetimes are stated by the maker under test conditions, so treat them as a guide.
Tube or batten?
If the fitting is old, cracked or yellowed, replacing the tube alone is a false economy. An integrated LED batten replaces the whole fitting and removes the ballast question entirely. Battens such as Philips' SmartBright range are slim and trunkable, so you can join several in a line.
If the fitting is in good condition, a tube swap is quicker and cheaper.
Buying in bulk
Some tubes are sold singly, some in packs, and some by the box. For example, our wholesale Loyal tubes are sold 25 to a box. Ask whether the price changes with quantity, and whether you can mix lengths in one order. Pricing is discussed per project.
Order spares. A few extra tubes of the same batch avoid mismatched colour when one fails in two years' time.
Plan the swap
A few habits make the job go quicker.
Work area by area, not tube by tube. Label what you have done. Keep the old tubes together and don't bin them with general waste, because fluorescent tubes contain mercury.
Schedule noisy or disruptive work for off-hours where tenants are around. Test one area first, check the light level and colour, then roll out.

FAQ
Can I replace T8 fluorescent tubes with LED directly?
Often yes, but check the fitting. Some LED tubes work with the existing ballast or starter, while others need the starter removed or the fitting rewired. The product listing says which. Rewiring is not a DIY job.
Do LED tubes need an NEA energy label in Singapore?
Yes. Since 1 April 2024, T8 and T5 LED tubes of 500 to 1500 mm are regulated lamps. They must meet NEA's minimum energy performance standard of 100 lumens per watt and carry the energy label.
What size are T8 tubes?
The common lengths are 600mm (2ft) and 1200mm (4ft), with a G13 base at both ends.
Is it better to replace the tube or the whole fitting?
If the fitting is in good condition, replacing the tube is quicker and cheaper. If it is old or damaged, an integrated LED batten replaces the whole fitting and avoids the ballast question.
Do you supply LED tubes in bulk?
Yes. We stock Philips, Loyal and other LED tubes, some sold by the box, and pricing is discussed per project. WhatsApp 8837 6682.
