Photon LED is a UK based company producing some of the most powerful Grow lights on the planet.
It is the Photon mantra that in order to create the best grow lights, two key issues must be addressed – the quality of light spectrum & light intensity.
During the 1970s, a Dr Keith J McCree revised and created “The McCree Curve”. The McCree Curve outlines a plants average response to different colour wavelengths and each wavelengths importance to plant growth. Photosynthesis occurs mainly between the wavelengths of 400nm (deep blue) to 700nm (far red) and this range is referred to as Photosynthetically Active Radiation (PAR). Don’t worry it’s not the bad radiation that we hear about spilling from those nuclear power stations, remember lumens for humans & PAR for plants. Taking this knowledge into account, it is widely accepted that a grow light emitting as close to the McCree Curve as possible will naturally show a higher rate of photosynthesis to one that does not. The basic upshot of this – faster-growing plant with naturally higher yields.
Photosynthetic Photon Flux (PPF)is the measurement of the number of photons in the 400 – 700 nm range emitted from a light source – simply put — light intensity.
Photon LED modules are designed to output the MAXIMUM light intensity to encourage higher levels of photosynthesis. Each Photon lamp contains 144 individual 1W LED’s which collectively output a massive PPF of 125 umol/s or 2.02 umol/J.
(umol – Micromole: per second and square meter (µmol m–2s–1). This term is based on the number of photons in a certain waveband incident per unit time (s) on a unit area (m2) divided by the Avogadro constant (6.022 x 1023 mol-1). It is used commonly to describe PAR in the 400-700nm waveband )
PPFD (Photosynthetic photon flux density) is the number of photons that land on a given surface area from a stated height. When comparing PPFD values of different lights, it’s essential to look at multiple measurements of each light rather than just one. Manufacturers can easily create lights which band together LED chips producing huge PPFD figures, you’ll notice however that these lights soon have diminishing PPFD values when measurements are taken outside of this small centralised footprint.
LED light fixtures are renowned for their efficiency and their ability to produce enormous PPF and PPFD readings. Photosynthetic Photon Efficacy (PPE) is a useful measurement for grow light comparisons as PPE measures how effectively a light turns electricity into PAR photons; measured in μmol/J where the higher the measurement, the better the light.
Another advantage of LED technology is that fewer watts are drawn to achieve a high PPE. Photon LED 7-way draws only 455w to produce more PPF than a 600w HPS, saving 145 Watts. Photon units are also passively cooled through their solid state heatsink technology, this coupled with an overall cooler running temperature not only allows more light fixtures in a certain space but also reduces the risk of fire. The heat expelled from Photon LED™ is significantly less than HPS bulbs, this also has the potential to further reduce bills as air cooling units would have to draw less electricity to cool a given grow space, and on smaller operations, air conditioning may not have to be used at all.
You will also need to consider the efficiency of the unit you are using and how much it will cost. Say a traditional 600w HPS Lamp run by a traditional electrical Magnetic Ballast may cost you £10 per week to run depending on your provider’s tariff. Plus you need to change that lamp every 6 months, so it cost you on average of £480 on electricity and £50 per year on lamps that equals £530 per year. When in comparison if you purchase a LED Fixture it would cost you an average of £300 per year to run without having to change the lamp. Most LEDs have a lifespan of 5-10 years saving you between £1150-£2300 in electricity & £250-£500 in Lamps (Average Electricity = £1725 and £375 saved in lamps) compared to an HPS lamp. When you look at it like this even the top high spec LEDs would have paid for itself via the savings you have made.
(All stats are based on a 7-way Photon LED configuration)
Consuming just 65W per unit means Photon LED™ far outpaces competitors. With the recommended 7-way configuration, you’ll still only be pulling 455W from the mains. When compared to 600W High-Intensity Discharge (HID) lamps, that’s almost 30% difference; saving you money on the cost of electricity.
It is quite possible to customise your Photon LED™ system to have an immense 30 units, that’s up to 4 x 7-way configurations, all running from one domestic mains socket without any relays or contactors required. With extension leads, don’t worry about having to connect them all into one behemoth of light, you can space them out and fill your whole grow room.
The Photon LED™ was designed to fulfil the needs of any grow, whether it’s a 0.16 m2 tent, a 10,000 m2 facility, an oddly shaped room or a greenhouse, we have you covered. Bearing the plethora of settings, you could find yourself growing in during the design phase, led directly to the product you see today. A solid, competitive, easy to use product that is suitable for both hobbyists and commercial ventures alike.
