its a standard Digital ballast for SE bulbs.
Pretty soon you guys are going to get loads of data including par data from 36 different points. Also, I will compare data to Lumatek ballasts with Hortilux Super HPS bulbs.
I did some testing with my Solic Tek Ballast vs the Gavita on the Agrotech The par was much higher on the Agrotech..All my data is on another site I cant get back on.
Im using a 5x5 for that light, the E-P are getting A 4x4 area with some overlapping. Im using a distance of 25-30" from bulb to canopy on 1k setting. If I use the 1150 setting I would use the 30" or more.
DGS what would you use for canopy distance on the 1150 setting.??

If you don't worry about cooling, definately go for the ePapillon 1000W's.
Photosynthesis are 3 main ingredients: light, CO2 and nutrients (+water).
It's all about the weakest link. Up your light, up CO2 and nutrients.
If you worry about the amount of light: Replace 12 radiant 8's by 8 ePapillon 1000W's. They will probably give you the equal amount of light.
I made a little picture that shows what the ePapillon is all about lighting wise when it comes to overlap!

Hi DGS, thx for creating this thread. Trying to figure out if I should shell out a few extra bucks for your ePaps over gravitas.
Your drawing from the post above shows as if those lamps were spread 2' on center, but correct me if I'm wrong, don't you guys recommend a 5' spread. If I'm right, the overlap on the picture is a bit exaggerated?
(I got to those numbers by comparing the width of the hood with the distance between each hood, 5 to 8 respectively. EPaps width equals 9.1")
The ePaps manual gives no instruction for cleaning the reflector, are there any recommendations for cleaning and products to use?
Will dirt stay on there harder with longer cleaning intervals or will reflectivity diminish more with multiple cleanings?
Last question, grow rooms usually have a lot of air movement. Personally I will have cold Ac air blowing down from above at about a 45 degree angle. My biggest concern between ePaps and gavitas is that cold air may hit the bulb in your style hood, whereas the gavita would have to have air come up from below to hit the bulb. These bulbs are temperature sensitive, right? Have you guys done any performance tests to take this into account?
If anybody using ePaps has looked into any of these issues please chime in.
Thanks again, any info will be helpful.
This is the lightspread on a 12' by 28' canopy using the ePapillon 1000W fixtures in a 4' by 4' layout.

How did you determine this? Not trying to give you a hard time or anything just really curious@drknockbootz and @habeeb
You can buy the ePapillon products through our distributor Dutch Garden Supplies
They can tell you where you can find your closest retailers.
Because the material of the reflector doesn't get really hot, dust etc doesn't burn into the material, so you'll loose only about 1% efficiency a year.But I can imagine you will want every percent of light to be used. So replacement reflectors are also sold.
Anyone know how the difference is in the spread using these dual ended HPS bulbs in a Adjust a Wing vs these ePap fixtures?
I just noticed that Adjust a Wings now has a model that takes this same bulb. I know how popular those are for growing so was curious.
Spread is the same. Its the same reflector.
Its just a different fixture they swap out for the single ended fixture
Intensity should be slightly increased.
I want 1!

How high above the plants do you recommend for the greenhouse? Someone was mentioning somewhere they they are meant to run up higher in GH and create a 9x9 footprint? Could you touch on this please? Thanks for your time
