Retrofit T8-to-T5 Converter Kits convert fluorescent "strip-lights" to T5 tubes.
Adapters for fluorescent lighting from 2ft up to 8ft T12 tubes.

 Use T5 energy-saving tubes in standard 2ft, 4ft, 5ft, 6ft, 8ft fluorescent lights 

T8-to-T5-adapters fluorescent batten-style tube convertersThe ClickSave T8-toT5 adapter.
Slim T5 tubes (available from trade suppliers) can last much longer than T8 or T12 tubes, reducing maintenance costs. Flicker-free too.

These adapters avoid the wasted energy of a light-fitting’s ‘magnetic’ wire-wound ballast which can use 20% extra power over the tube's rating!

Batten-style adaptor with low-energy HF ballast and holds thin efficient T5 tube. Replaces Fluorescent Tubes in standard light-fittings (or 'striplights').

T8 and T5 energy saving retrofit tubes

Thousands of our T5 conversion retrofit kits are in use in the UK in schools, offices, retail, leisure, industrial, government, local-authority  ....many via The Carbon Trust, Salix and European funding

Why is ClickSave the best T5 Converter Kit for you?

ClickSave is not a tube-extender, with ClickSave your lights use less energy than with standard plastic 'end-cap' style T5 adapters like these which don't have built-in reflectors:

Why choose an energy-efficient T12 or T8-to-T5 adapter with a reflector?

T5-adapter-with-reflectorMost sizes of narrow low-energy T5 fluorescent tubes are not as bright as the equivalent-sized T8 tube.

In most buildings our bright reflector maintains or exceeds existing light levels.


End-to-end light
- even with your 6ft and 8ft T12 fluorescent lights

two-Tube 2-tube 6ft 8ft T5-adapter
other 6ft T5 adapters leave large unlit areas at the ends of the light-fitting. This is because T5 tubes are only made up to 1500mm (about 5 ft) so other types of T5 adapter use a single shorter tube (such as 1500mm tube in a 6ft light-fitting). ClickSave 6ft and 8ft T5 Adapters use two T5 tubes end-to-end for continuous light.

Advanced preheat ballast - for longer tube life
Preheat warms the tube so large start-up currents are not needed.
This gives the best life (the most start-ups) from tubes. No short-tube-life like old 'switch-start' caused.

We can also supply LED tubes which cost more but use slightly less energy:

ClickSave T12 or T8 to T5 adapter kits can also be used to adapt electronic ballast high-frequency (HF) fluorescent T8 fittings (fixtures) to use T5 tubes. However please bear in mind that your high-frequency fittings are consuming less power than the same style of fitting would if it had a traditional magnetic ballast. For this reason your savings will be lower. You will also need to follow our isntructions to modify the internal wiring of the light fitting.

Need shatterproof T5 lighting?

Should I fit LED tube converters or T5 tube adapters?
LED tubes or T5 tubes? LED tubes are a little more efficient but they cost much more, so payback will be poorer.

Or if the lamp-holders are too corroded to give stable power to a T5-tube retrofit unit you need to wire your adapter into the mains bypassing the ballast:

Wired T5-tube-converter (not standard - please specify at time of order. Delivery may take longer.)

Why choose a retrofit tube holder wth reflector?
Light at ground level will be brighter with reflector compared to a non- reflector tube-converter

What if your fluorescent light-fittings already have reflectors?

Reflectors become dirty and dusty so do not reflect enough light. Also most lights' reflectors do not extend to the back of the light-fitting so much light can be lost behind them - the reflectors of ClickSave T5 adapters are about the same width as a T12 tube so fit is not usually an issue.
