HLG 550 V2 RSPEC LED GROW LIGHTS UK & EUROPE… Replaces 1000w HPS Grow Lights

  • Are you looking to produce a bountiful harvest or two?
  • Are you looking for the best LED grow lights in the UK and Europe?

If the answer is yes to both those questions, then you need not look no further than the Horticulture Lighting Group’s Flagship model the HLG 550 v2 Rspec. This lamp is designed to be used in grows that require high intensity lighting, making this led grow light perfect for plants that love lots of light, like Aubergines, Cucumbers & Tomatoes.

An Industry First and RECORD BREAKER

Due to it’s phenomenal performance and exceptional energy efficiency, the HLG 550 v2 Rspec achieved an industry first & record breaking level of 2.67umol/J and 1293 PPF, whilst only consuming 484.1 Watts, this means it can more than hold its own against a 1000 watt HPS grow light. Another industry first, as it is the only lamp in the world at this power, that is able to do so.

The HLG 550 v2 Rspec total PPF output was measured and verified in an independent test, carried out by a third party Laboratory, and it is currently the industry benchmark, as there is no other led grow light manufacturer on the planet that has produced a fixture this low power, which is still able to keep up with a 1000 watt HPS grow light.

Double your yield with the 550 Rspec Groundbreaking Performance

With its truly groundbreaking performance, as you can see the HLG 550 v2 Rspec really does produce a huge amount of light from a relatively small amount of power, so much so, you can remove that 1000 Watt HPS grow light from your grow room, and replace it with an HLG 55O v2 Rspec. No joke!

This is a grow light, which comes with a load of added benefit’s such as…

  • Low power consumption,
  • Superior spectrum.
  • Double your yield per watt vs 1000W Hps grow light

…and more light per watt than any other grow light on planet earth, today.

High Electric Bills Gone Forever!

In fact, watt for watt, the HLG and QB series led grow lights produce 100% more light than a typical Single-ended 1000w HPS grow light.

“This means you get to enjoy an extra 100% more light per watt, than a typical 1000w HPS grow light, yet still reap the rewards of a bountiful harvest, without the added hassle of sky high electric bills, and all that excessive HID HPS heat.”
