Envirolux's newest Pro Rail grow light

[sammyz2646]

I am now remembering a conversation I recently had with the LED guy down at Envirolux about my failing unit from Green Guy LED.
Maybe he didn't know exactly what unit I had , but he assured me that it was a sealed chip on board and was unrepairable. I really don't know, but fixing it would put that $1200 back to work like it should be.
Does anyone think I can order these cob's and replace these without breaking some sealed unit?
I think the cobs are 32x3w
Here is a link to the units themselves-

The website is so poor and little information is posted about the unit

Any help would be greatly appreciated

with all the little lenses butted up against each other, not likely to be cob

A cob is a small flat chip made up of a number of individual diodes/leds. ~ 32 @ 3 w chips fits on a < 1" x 1" surface

Here's what cob looks like

Still that light should be modular, so if one bank is out, it should be replaceable, and the others should work. If not, wow, what a crap design

Trying to share photos

tips on photo uploads?

I have had issue for years on this site sharing photos. I must be stupid or missing something easy

Maybe these are re-branded Houyi lights? See here:

They make these in 50, 75, and 100 watt COBs I believe. My guess is that this is the 50 watt COB model you've got if it is stated to be 800 watts (in actual draw more like 480). They make reflectors in 70, 90, and 110 degree angles, each of which sells for $1.20 from them. Seems like all this guy did was paint the case green and mix up the reflectors used...

 

[sammyz2646]

Yes! I believe this may be closest to the truth. Thank you.
So my question is that if these parts are so cheap, why wouldn't this guy just send them to me?! weird

I have had issue for years on this site sharing photos.

Is it when you try to upload them? You most likely need to reduce the photo when you're exporting it out of your photo program.
I run iphoto, when I export a shot for here, I change it from full size to large or medium.

Uploading to the site: On your 'My IC' , see the column to the right.
Click on 'Pictures & Albums'. You may want to create albums as you go, but hit the 'Upload Images' button upper left. Now you click on the 'Browse' button and load your pic one @ a time. Try one by itself 1st. It will not be able to do it if the pic is too big, and will tell you so.

If you successfully imported the pic and want to put it in a thread, you can do it one of two ways. When replying to thread, you can put a thumbnail pic by simply clicking on the 'Insert Images' button to the right of where you're replying, under the Smilies and then clicking once on the pic. It should transfer onto the reply.

If you want a larger pic, go to your album and click on the pic you want. Underneath it copy the BB Code. It will start with

.
Simply paste that into the reply text. Good luck! We want pics!

I constantly search Alibaba. Most lights are coming from Shenzhen, although they have different websites

If the cob pictured was the cob they sold it would be good value, but who the F knows. I have argued with them time and again about this very cob

They respond "Trust me!" I reply, how can I trust a company that posts misleading wattage and cobs, and who knows what else. BUYER BEWARE

Finally! Thank you so very much for your help Highlighter!!!!!

As you can see I have each rail hung independently for now as they are mailing me the rail kit
This is simply my test area for these lights only

 

[sammyz2646]

I have seen LOTS of lighting options over many many years and granted, my LED experience is limited, but this takes the cake for brightness and visible intensity without almost ANY heat. And for only 195 watts running total I am very impressed. Question is how will the plants respond? We shall see

The drivers are slightly warm to the touch as are the pucks, but so little...

I will take down one of the rails again soon and post another photo to give you a better perspective of its dimensions, etc

Not opening due to missing bracket on front end. I tried to fix it, but no

One other notable visible difference with these vs. other LED's that I have seen is the light diffusion system. These "pucks" emit a bright and intense light, without the usual "blinding" pain of most traditional diodes.
It almost seems as if the light is more equally dispersed in this manner as opposed to the traditional beam angle pointed right at the plant, which obviously limits your overall coverage/footprint. There is a cover that somehow equally diffuses this light without degrading it too much and I find it very bright still, but not painful as some other units to be around
This relates to other discussions in this forum about giant warm led light plants that are very intense but only in a small area, and supports the idea of spreading out all this light as evenly as possible, trying not to lose any intensity along the way, (that's the kicker)

I have some cigar hygrometers that are very accurate for temp and humidity and inside this cabinet in the photos it is only ~ 1-2 degrees warmer than the outside with a curtain drawn to enclose the area

Yes I put a SMALL fan in there but there is almost no extra heat

I am very excited about the future of horticultural LED's and as of now, I feel almost "addicted" to searching and finding the newest technologies and with the help of the lessons learned from everyone here, it saves us all from wasting our money on a untested and expensive unit

Just found this-

http://www.transcendled.com

 

[sammyz2646]

Confusion about where and what is sold to which company and where this stuff is REALLY coming from is setting in.

Transcend is in Illinois

Illinois? Vancouver? China? Holy . . . .

It may be easier on your eyes, but is it better for the plants? You can wear sunglasses

Even glass optic lenses/covers prevent ~ 10-15% of the light from escaping

Big selling feature for COB/Reflectors
