Photon Pro 4


We have many customers wanting to buy our old Photon led grow lights series so they are back.

Photon Pro is our popular series of LED grow lights featuring super-convex lens technology.  The lamp fires each LED through the super-convex lens to focus the energy and increase canopy penetration.  The lamp offers 6 spectrum output LED's for great all round performance and has the latest isolated supplies and high quality 3W LED's.

Super-Convex Lens Technology

 Photon Pro Super-Convex Lens

The new super-convex lens concentrates the light energy from each LED and increases the penetration through the canopy, yielding improved results lower down in the grow area.


The High Powered 3 Watt LED's   and thoroughly quality checked before leaving the factory


The spectrums we use are 440nm, 460nm, 610nm, 630nm and 660nm UVb & IR.



Cluster Controls - Allows even more power saving!

Photon pro power switches

Each Photon Pro lamp has its own power switches on the unit.  This allows you to switch the lamp on and off in a convenient way but also provides a useful feature -  As there are two swtiches, each controls half of the clusters so you can run the unit in half power mode when plants are younger and need less light, and change it easily to full power mode as you need.


Its a great way to avoid overkill with young plants as beyond some threshold, throwing too much light at them is both wasteful and non-productive. Save energy and take control with Photon Pro!



Heat Management

 Photon Pro fan - image

Whilst being hugely more efficient than other methods of turning energy into light, 100% efficiency is impossible.  Therefore LED's do generate some heat output and this needs to be adequately dispersed away from the LED chips themselves.  Note also that LED's spectral output is affected by the chip running temperature.  The bottom line is : the better the heatsinking and thermal management, the better the long term stability and reliability of the LED grow light.    


The an efficient heat transfer paste is also carefully selected and tested thoroughly for its best heat dissipation from the LED diode to Heatsink


The whole internal components & Heat sinks are kept cool by high speed quiet ball bearing fans.


The only slightly warm air that comes from this unit is generated from exhaust from inside the unit from the heat sinks which are designed to transfer heat away from the rear of the LED diodes themselves.  The fronts of the lights are slightly warm to the touch. So heat generation is almost Zero. This also helps the residual Humidity inside the area.


From Germination to Flowering, this LED is very capable of creating BIG yields, Big dense flowers and fruit and has been proven over and over again.

Superb LED!!!!
Superb little LED,. gives out a lot of output giving huge yields for its size, have been using mine for 2 years now and still getting 5+ oz from it in a 75x 75 x 200cm area & a 20L airpot.
Get it especially for small areas, you will not be disappointed.
