I'm a big believer in leaving the plants alone if they behave under indoor lighting..........I watched the stretch, thought it was over and they went another 16 inches above. Too late for light training with a low wattage single point light source, decided to snap the stems in the center but changed my mind when fungal issues arose. I have sanitized this room, but spores are always present.PSUAGRO - Do you still have room to move the light higher to have better coverage? I wouldn't normally recommend taking the lens off, but from looking at your situation, you might have to for better spread. Just a thought, do what you see fit.
Not to question your method or how you grow, but i'm curious to why you don't train your plants as well as lolipopping the bottom. I'm here to learn from the experts as well.
SDS - So I finally got a chance to follow up with some of the glass/lens manufactures that you recommended. Here is the outcome. Schott's rep said they don't make lenses any more. I guess they don't sell enough of it to keep that department open. Edmund optics lens cost 7 times more than what we get our lens for and most of there lenses comes from overseas. I'm sure from the same factory that everyone get there lenses from. Corning Pyrex doesn't have a lens that would work with our LED size chip. Thanks for the recommendation but we'll stick to our supplier for now. We don't want to add additional cost to the end user. Remember the most important thing here is the light engine, everything else is cosmetic.Type of optical glass used ,please ,for confirmation of claim.
Judging from the len's curvature,it's a type of glass with low refraction index ..
And it must withstand heat ,without cracking or chipping ...
Like Schott BOROFLOAT™ or Corning Pyrex 7740®....
It can be also S-FSL5,N-BK7,N-K5,B270/S1,Schott Zerodur®,N-SK11,
N-BaK4 or N-BaK1 .....

5-7% lumen lost ,is a pretty low figure ...
(Specially for that kind of thickness involved. )
So,of which glass type are those lenses made ?

Can't agree
Inferior lenses will cloud up over time. Just 5% will seriously impact umole output
Lol..true that. Just putting reflectors on heats my sink up more than without..can imagine what an enclosed one does.A random thought...the Lenz is keeping the heat enclosed...I know my cxas throw off a lot of frontal heat...with no where to escape...it builds up over a 12 hour period and combined with the heat on its back end prepares eggs for frying
I don't like my eggs well done at all...........runnnnnnnnnyyyyy for the winI dont like my eggz THAT well done....
Hope so friend........................I have my doubts due to the height of these lanky bitches with no training.Well that is why it is a test right? You did it right and proper the whole time. And just because this test light is done for now, doesn't mean the backups won't carry this to a beautiful finish.
Just as with all less(cobs or standard), more of them and running softer is the way to go.
I'm sure this feedback is valuable and will help the inno make the changes needed.
The old panel is untouchable when running in an 85f room with no air circulating around it.............will seeWow..doubt it's the heatsink. Maybe just pushing the led too hard. The cree household bulb 18w version get scorching and still have a 10 year warranty
Onward with the backup!
thought about it allot, but their so tall now unfortunately and will lose half the light to the middle of the plant........idk, I'm stuck.A random thought...the Lenz is keeping the heat enclosed...I know my cxas throw off a lot of frontal heat...with no where to escape...it builds up over a 12 hour period and combined with the heat on its back end prepares eggs for frying
Have you received the beta panel yet?? wanna know for certain what the issue was..............get back to meThanks for the update PSUAGRO, sorry to hear about the light. We use this heat sink on 100W before without any issues, so we know it can dissipate the heat. The only thing I can think of is the new heat pad that they just came out with. It doesn't look like it's transferring the heat from the COB to the heat sink that well / fast enough. The unit that you got is the first one used with that heat pad, that's why it a beta test unit. We're also trying out different thickness of the pad to see which thickness is best with different wattage chip. We want to make sure these issues are addressed and resolved before it goes to market for production. Once we get the bad unit back, we will conduct our own test to see what went wrong. I'm glad you're testing the light for us. Third party testing is always best because they're unbiased. We got your back on this project. We have a back up unit for you if you need it. Hopefully nothing else goes wrong. A hundred things can go wrong and only one thing can go right with growing.
Yeah another 3 weeks from today and they should be where I want them(15%-20% amber), I like that "heavy" smoke...PSUGRO - looks like your girls are filling up nicely. When do you think those will finished 3 weeks? Can't wait to see the finished product.
I got the fixture yesterday and mounted another 100w chip on the fixture and left it on overnight to see if the heat sink is the issue. Came in this morning to test the temp on the chip, it measure 91C. 91C is pushing the limits of operating temp of 85C with the ambient temp being 75F. Your room temp is averaging between 82-85F with really no fan circulation to cool the heat sink down. So the chip temp is running around 100C with the lens on it could be a lot hotter. I have no way of testing the chip's temp with the lens on so I can't give you an accurate number. My conclusion is the chip fried because of the high temp environment that the fixture was in. Doesn't look like the thermal pad is the issue, it's the heat sink in this case. We're going to use a bigger heat sink in the future just to be on the safe side.
In the past other small grower average room temp is between 74-76F with AC and fans running so it was never an issue.
Really????????? read post #148^^ again friend..............I'm confused. Did you have 2 fixtures from innoled or did they send you a replacement? You had the 118w. Now the 120w?
