Easily replace fluorescent tubes with LED

4000K vs 6500K

The Osram SubstiTUBE LED Tube is a cost-effective replacement for your existing fluorescent lighting.

  • Reduces energy consumption by over 50%
  • Designed to operate for 30,000 hours
  • No electrician required in most cases - install it yourself (see guide below).

Fits all standard T8 light fittings '4 foot' (~1.2m) in length. This item replaces regular 36W fluoro tubes with an 18W LED.


Reduce T8 'fluro' tube energy consumption by over 60%

Regular T8 fluorescent lamps consume 36 Watts of power with a further ~9 Watts lost in the magnetic ballast. As a result, total power consumption per lamp is actually around 45 Watts.

The Osram SubstiTUBE T8 LED tube, on the other hand, consumes just 16 Watts in total. That's an energy saving of up to 60%.

This means you'll save over $30 per year in electricity costs, for every tube upgraded. This example assumes 12 hours per day operation and an electricity tariff of $0.25/kWh.

Installation guide - 4 Foot (1200mm) LED Fluoro Tube

There are two main types of fluorescent light fittings in existing buildings:

1) Magnetic ballast fittings - with starters. These are the most common fitting type. Simply replace the tube and starter (supplied) and you're done! Magnetic ballast fittings are identifiable by the fact they have starters present.

LED Tube Installation Guide

Easy installation for any fitting with a starter.

2) Electronic ballast fittings - no starters. Unlike the example shown above, these fittings do not have a starter. These units will require an electrician to 'wire out' the existing ballast. Fittings without starters that come on instantly are generally electronic ballast.

A direct replacement with less lumens?

Lumens are a measure of total light output. It is true that the Osram SubstiTUBE LED tube produces less lumens than a modern T8 fluorescent tube.

However, regular T8 tubes release their light in all directions (360˚). Much of this light is lost in the fitting and to unused parts of the room.

The Osram LED Tube only directs its light output downward, where it is actually needed. It still spreads light throughout the room, but without losing any light to the fixture or ceiling.

Price includes LED starter

Don't forget to check the packaging for the LED starter. It's easy to miss if you happen to open the package at the other end!

The LED starter is essentially just a safety fuse. It allows the LED tube to work in your existing light fittings, with no further modification.

Secure delivery of LED tubes

We deliver these LED tubes via courier, as they are too large to be delivered with Australia Post.

You are welcome to order any number of tubes, but we generally recommend purchasing at least 2 tubes to ensure safe and secure delivery. The Osram SubstiTUBE LED tubes are packaged into cartons of 25 units, so multiples of 25 are worth considering where appropriate.

In the unlikely event that any damage does occur during transit, just let us know and we'll replace the goods at no cost to you.

Frequently Asked Questions

What other options and sizes are available?

You may also require "half length" 2 foot LED tubes, or the longer 5 foot LED tubes. If you are upgrading your office lighting we'd recommend that you consider these LED troffer lights designed for t-bar suspended ceilings.

Which is better: 6500K or 4000K?

4000K vs 6500K

One colour temperature is not really "better" than the other. Generally 6500K is a "whiter" light and is perceived to be slightly brighter. If you want these LED tubes to look the same as the fluro tubes you are replacing, look for '840' or '865' on your existing tubes. '840' is 4000K and '865' is 6500K.
