There are two aluminum type grids that I assume are the heat sinks. All the other parts are working. I was wondering what those Zener things were for. The other light does not have those. Yes I am considering doing nothing at the moment and doing some research on diy cob led. And using these...

Had this kicking around in my tool box and used it to check each diode. None of them responded which means everyone of them is out? The driver is fine I have determined that. I also used the meter on the connection and the metre lit up. But no light from any diodes. I would think I have to...

I don't have as many screws... my first panel was neat and tidy.. kind of easy to figure out. the 2nd is 1/2 out. 2 drivers, one running each side. it appears the one side has dimmed...and they aren't completely dead. Some diodes are not working however. Were there no fans in this unit you...

so the plant is normal?

Can you replace those diodes with 3w COB? If his doesn't work or regardless I may attempt a small project once I research some DIY on these lights.

That's no big deal cost wise. I have some photos of the diodes... from ebay as well. Now if the entire string is fried... it must be something else. If I go through with the wire and test all diodoes and the string never liights, then I take it they are all fried or it the connector to the...

I understand MechMike all what your are speaking of... there is an aluminum board screwed to the led board. Keeping some of the insulation on the wire grounds me! Right? Does the colour matter.. like copper vs silver... or the colour of the insulation. I can do all this I am pretty sure...

Mine is like a gun... and yes I know what you are talking out for the pencil type. I may be able to find one somewhere. Dad made amplifiers many many years ago with tubes etc.

I have all my dads tools. He passed and mom did as well. I bought their house and kept his tools. Hence the soldering iron or gun. Some would through it out but I figure even if I didn't really know what to use it for or how there would be a day. And here I am.

I do have a soldering gun. And the flux or whatever you call it. Any any peice of wire? Take off the plastic or insulation, bend to a U and touch each end of that to the pos/neg on each diode. The one you hit with the wire if the board lights up is bad. Take new diode and replace by soldering...

Yes, I have seen those on e-bay. Maybe I will try that and have my brother fix it for me. A project for him. These are kind of like the xmas tree lights... one goes out and you have to find that light and replace it. Only these are soldered to the board, not pull out.

For me I think replacement is a better option. I get a lot of what you are saying. Have NO idea what a heatsink is but will Google it. I like the building of a COB based light but have no idea what I would be doing. However I am willing to read and learn which is what I have done to this point...

I'd say heat stress too.

I purchased some autoflower seeds a while ago. Just to try them out. Cheap ... 10 seeds $15. Now most of those turned out to be male and finally a female. Her date of going into soil is September 17/14. I see obvious signs of flowering but given her age I would have thought it'd look...

I did the same with my LED's. And the same 'string' of lights is still out. Must be the diodes. Or the little cord/plug that it goes into. They do look fairly simple. There seem to be wire and plugs not plugged into anything as well. No hot glue everywhere tho. Mine does look neat and tidy. Here...

Thank you for your support and advice~!

Hey People: I have one plant in DWC as a test run. Going very well so far. I have just flipped to 12/12 and the nutrients that are currently in the res are for veg. How do I introduce my flowering nutrients. Do I add gradually over the next few weeks until it's time to do a total res...

Green slime is algae. Cover the tops of the pots with tin foil and leave just an area for watering.

Hahah come to think of it so am I.

WOW!
