[pHive.8]

i just have read some discussion about our reflector vs others on this forum, as i do not want to post in the threads of our competitors we are starting this thread for everyone who has questions about our products.

[pHive.8]

Lights interaction uses different versions 600W and 1000W reflectors.
Our 2006 to 2012 1000W model has a wide light spreading angle, these luminaires are 400V line-line only.
The NEW E-Papillon 1000W 240V which is on the canadian and USA markets has a much smaller light spreading angle.
where the old model has an angle of 140 degrees over the y axis of the bulb the NEW E-Papillon reflector is only 120 degrees in angle.
The NEW E-Papillon reflector combines the advantages of an open reflector with the smaller beam angle of a closed reflector but with still utilizing superior uniformity of light and heat. because the higher uniformity in light and heat you can place the reflector closer to the canopy.

Do you have a chart for the umol spread at different points on a 4x4 ?

What are the main differences between your reflector vs the gavita?

Glad theres someone here to representing the papillon.

I'm glad to answer all questions!

The main difference between is that the reflector utilizes Open Reflector Functionality, which directs more light on the canopy while trapping considerably less heat. Heat is allowed to rise away from the canopy more efficiently than other reflectors that trap the heat and cause hotspot in the plant canopy.

Because of the unique design of the reflector, much of the heat flows through the reflector and into the rest of the room, resulting in lower canopy temperatures and a more even temperature throughout the room.

The ePapillon uses a safety cover that provides a thermal buffer between the hot reflector material and any objects that it may come in contact with. The protective cover reduces the surface heat from 390 degrees down to 122 degrees.

This is the lightspread on a 12' by 28' canopy using the ePapillon 1000W fixtures in a 4' by 4' layout.

So Whazzup posted the following:

============================== ===================

It is really simple. The e-papillon is a wide reflector, which is by nature less efficient and penetrates not as deep as our design reflector. Furthermore in any room you will have much higher wall losses from a wide reflector. I have just seen the manual of the 1000W papillon and they recommend about the same distance as our reflector, even a bit more. That will certainly result in lower light levels.

The plus is that the lower light levels will result in less heat on your plants, but do you really want lower light levels and less penetration?

It is not true that the e-papillon generates less heat: it just distributes the light (and heat) wider. Light on your walls will be partly dissipated in heat, and that will also warm up your room. So less reflector efficiency and more light on your walls, together with less penetration makes this reflector imho less suitable for indoor growing. If you love light you need to cope with the heat, it's that simple.


============================== ===================


What's true and what's untrue in this story:

The ePapillon is a wide reflector: Untrue.
An open reflector doesn't make the reflector a wide reflector. The lightspread is 60 degrees to both sides.

That will certainly result in lower light levels: Untrue
Like Whazzup has posted before: You light a room, not a table. Reflectors need overlap.
The ePapillon reflector will result in higher lightlevels measured in a room with a 4'by 4' setup or any other similar setup.

It is not true that the e-papillon generates less heat: it just distributes the light (and heat) wider. Untrue
Efficiency means: all electricity that hasn't been converted to light will become heat.
Because the reflector is more efficient it will generate less heat.
Next to that, the heat is distributed more even across the room because of the open reflector.


less penetration: untrue.
The ePapillon reflector was designed to reflect the light in different angles.
You don't want the light only directed downwards. The light in the angles will be light that is directed into the canopy.
So every plant will get light in different angles. The leaves of your plant aren't all only directed upwards...





If you love light you need to cope with the heat, it's that simple: Untrue
Just buy the right type of fixtures.... and measure for yourself. The heat in your growing room will be less high.



Did you know that Philips dictates the following for the GreenPower 1000W EL lamp:
Lamps are designed for use in open luminaires, when used in closed luminaires, overheating of the lamp will occur.



The 1150W boost function will not have any effect in lifetime of the Philips lamp in an open reflector.
Why? The heat is distributed better.


Did you know that every 10 degrees centrigrade will result in a 50% higher failure rate of the electronics.
A closed reflector will heat up the complete fixture. An open reflector distributes the heat to the surroundings, not to the fixture itself.
Measure the temperature of the housing of the electronics and see for yourself...


But do take a look at them for yourself and be the judge yourself, don't take my word for it...

i have some questions for you dgs

Hi DGS

The E-Papillon reflector looks to be a very interesting concept

Are these reflectors for the 1000 and 600 availabe in a remote ballast version.

Cheers
