Actively Cooled Dimlux Lighting for a Massive Boost in Output Levels

This Nanotube version of the Dimlux Expert Series 1000w fixture is capable of boosting double-ended 1000w / 400v grow lamps by an enormous 20% (instead of 10%). The Nanotube can deliver yields that are approaching 10% higher than the regular Dimlux fixture (which was renowned as a big yielder anyway!). This is due to the fact that it facilitates improved ventilation, allowing you to channel hot air away from your grow room, keeping your room running optimally at higher output rates.

  • Uses the innovative Nanotube system, removing heat before it enters your grow room
  • Runs lamps at 20% overdrive!
  • Loved by commercial growers and known to deliver phenomenal yields
  • Combined lamp, ballast and reflector
  • Utilises ultra-high frequency 400-volt technology
  • Extremely high PAR levels (useable plant light)
  • Runs from a standard residential 230-volt mains supply
  • Highly efficient, with an extremely low heat output
  • Ideal for grow areas of around 1.5 metres square
  • Alpha Optics 98 reflector for a beautifully even light spread

How the Dimlux 1000 Watt Nanotube Fixture Works

The key feature of Dimlux's 1000w Nanotube unit is the 20% boost mode, effectively turning this fixture into a 1200 watt system. This is made more practical for your grow room by using active cooling. Users of Dimlux fixtures will be aware that previous models had 50mm vents connected to the reflector. These vents allowed you to remove excess heat before it affected the grow area. The Nanotube model takes this concept and pushes it to the next level by reconfiguring the internals and including two vents: one for 'air-in' and one for 'air-out'. Cold air is pushed into the unit via the vent closest to the ballast. It then moves around the fixture, removing the heat generated by the ballast and lamp, after which it's exhausted via the vent closest to the reflector. This technology allows you to get the very best performance possible from 400v / 1000w equipment.


The lamp is encased in a glass tube, forming a sealed unit. The air that you push through the fixture never comes into contact with the rest of the room. For this reason, there's no need to worry about smells. Air is pulled from an outside point, through the fixtures and back out without ever getting contaminated with odours. One less thing to have to think about!

You'll notice from the image below that typical set-ups use two ducting runs. A long, straight length of ducting for the cool air coming in and another ducting run for the warm air out. Both feature an end stop on one side, which directs air through the system in a loop.


You'll need to make sure that your fan(s) generate enough air movement to remove excess heat effectively. As a rule of thumb, aim for at least 120 cubic metres of air movement per hour for each fixture. If you're running 1-5 fixtures, you'll be fine with 5-inch ducting. For 6-9 fixtures, you'll need 6 inch ducting. For 10+ units, go for 8 inch ducting. Don't be afraid to experiment with different configurations when creating your setup as long as you ensure that fixtures get adequate airflow. For instance, the 'cool air in' and 'warm air out' ducting runs can be split into multiple lines using Y-pieces.

Why Choose a 400v Lamp?

Used by the professional horticultural industry, 400-volt HPS lamps have a number of key benefits which make them superior to standard HPS lamps – even ones run from top-quality digital ballasts. A 400-volt HPS lamp is much more efficient than a standard HPS lamp. Both systems consume 1000 watts and therefore cost exactly the same to run but the Pro HPS lamps run at a higher voltage and a lower current. 400-volt Pro HPS lamps produce more light for the same power consumption and will give at least 10% higher yield compared to even the best standard HPS systems. In fact, when they are seen side-by-side, the HPS Pro lamps are noticeably brighter, run cooler and the light they produce is slightly whiter. So in addition to them giving a higher yield, plants grown under a 400-volt Pro HPS are healthier, happier and are at less risk of heat damage too

How to Use the Dimlux Expert Series - 1000 Watt Grow Light:

Simply hang the combined ballast & reflector over the centre of the grow-space at an appropriate height using easy rolls or jack chain. Run the 4.0m kettle lead from the reflector to a standard UK mains outlet or your contactor and switch on.

When using the Nanotube functionality, always ensure that the air that's sent through the fixture is cool, dry and free of dust.

For information on swapping out lamps, see the following blog, which features a complete guide.

Dimlux lighting is best used in conjunction with the Dimlux Maxi Controller, which will regulate on and off times, as well as performing host of other features like sunrise / sunset, auto-dim and auto-shutdown. You can power multiple Dimlux fixtures using the following power supply units:

Green Power Powerbox

When HID lamps are switched on they run extremely hot. As with all high pressure sodium and metal halide bulbs it is necessary to avoid touching the lamp with anything such as fingers or plants as this may cause severe burns or fires. In particular avoid sprays or liquids coming into contact with the lamp as this may cause premature failure or even an explosion.

Please note:
Ensure that you follow manufacturer's guidelines when fitting your double ended lamp, as incorrect fitting will result in damage. This damage is NOT covered under the manufacturer's warranty.
