G2-800w PARmaxx parabolic refraction integrated full spectrum LED grow light - 4x4 cr

I'm not quite sure what you are asking me to do here?

Perhaps he wants a measurement from 20" from the side of the light fixture to see if and/or how much the light degrades? I would say take a reading at the canopy top then move the meter 20" to the side and see what it reads? I'm only speculating of course but that would be a way to see how much coverage is ideal for the fixture. :)
 
hello i have the 450w G2 and ive only used it for now 48hrs and the middle light has already gone out.. not looking good for a $800 unit.. i just message magnum hope they fix it or replace the light..

They should if it is still under warranty. What are you growing? Got any pictures of the grow and the bad light?
 
I guess the better way to put it is, If you hang the light 20" off the floor what does the footprint measure compared to the light it self. mine measured 24"x26" and had a footprint of 40"x42" @ 20".
 
Sort of. More to it than foot print. Lumen output at the perimeter is important too

wouldn't it be the PAR values rather than the lumens? from my understanding lumunious flux is how the human eye measures light intensity and PAR is the absorbable light between 400nm-700nm that the plant uses to produce chlorophyll A&B in photosynthesis???
 
Day 24 of flower. Fed today, looks like the stretch is done. The chlorophyll dissipation in the fan leaves of the center plant is somewhat evident, the taller plants around the perimeter that are very close to the fixture have no signs of chlorophyll dissipation. Bud production is looking good to me at this stage of the grow. The CalMag issue is under control, I'm using double the recommended dosage on the calmag and i'm running my nutes at about 130% of the recommended dosage as well. The feeding/watering schedule seems to be every 2 days and on water days the calamg has to be in there.

Thanks for the update N2L. They are looking really good! The taller ones look like they will be grabbing that panel soon. :)
 
Thanks man!

The pleasure is all mine bro! I love how your plants are reacting to that panel! Please keep doing what you are doing and posting updates when you can! If you ask me we have too few growers stepping out of the box and doing what others are afraid to, whether out of necessity or out of a pioneering spirit, it is so good to witness it here. It will give others hope, like me, that they too can use LED panels in their grows from start to finish, in such confined spaces, and produce quality medicine for themselves and others. So thank YOU for posting your amazing results N2L!!! :) :clap::peace:

Exactly right N2L. I suppose the best way to check the footprint is to set the panel at 20" then measure the PAR peak at the center on the ground then move the sensor to each of the 4 sides and mark where the PAR begins to drop lower and that would be the panel footprint. Of course that is in my limited understanding of it. :)
 
20131001_185839.jpg20131001_185846.jpgHere is a few pics of the light.. been trying to call for almost a week and no one has called me back or anserd the phone.. light is only 3 mouths old.. so will in the warranty.. hope this not one of those companys that say they have a warranty and dont fulfill it.. other then the 1 light going bad. the light looks to be doing good.. wish magnum or greenguy whould call me back.. i hope my $800.00 was not wasted on JUNK.. and NEW2LED if u know someone working with magnum or greenguy post something that i can use to get it fixed plz... Thxs and your grow is looking good BTW..
 
just sucks because ive only heard good things from magnum. and for them to not anser there phone at all seems fishy.. but im hoping new2led may have some ansers for me.


Sorry I can't help you out bro, that light looks like one of those old flash bulbs from back in the 70's. Anytime I have questions I just send them an email on the website and they always get back to me pretty fast. Other than the blown light how is that 450w?
