FRUs, like the fan and driver, are what are typically sent to customers for self service. Soldering new components onto a PCB is something I've never been asked to do in two and a half decades of IT and related tech support, dealing with thousands of different devices and hundreds of different companies.
Our debate centers around what constitutes a "part" that is field replaceable. Both the fan and the driver are composed of many separate parts yet are shipped as one part. I logically expected the panel to follow suit. Just like I wouldn't be asked to replace half the bearings in the fan, or melt a new blade on (for example purpose ONLY), I expected to have a part delivered that would be easy to replace, just like the fan and driver.
Yes, when we were talking about parts that are easily replaced in the field, like a fan (not parts of the fan) and a driver (not parts of the driver). This quote is taken out of context and is from before I tested the part of the panel with a different driver.
I can handle unscrewing this panel and shipping it back to you, rather than discarding the faulty parts as I am expecting you to want with the fan and driver. I personally can handle soldering dozens of tiny diodes onto a board, but I don't believe you can expect any significant portion of your customers to do so.
Now that it's failed twice in the first half of the warranty period and 25% of the components within the device have been replaced, by me, will my warranty still be honored for the remaining 6 months?
I don't feel I've disparaged Mars-Hydro, and I remain a customer, but the extra credit would have been earned by shipping me FRUs from a North American location, so that they would arrive within a week or two and they can be easily and quickly replaced on site. I have the majority of the components, but some of the LEDs were shipped from China and haven't arrived yet.
Thankfully we ordered a replacement 900 right away so that our grow isn't affected, expecting an elongated time to resolution on this light . The new one is the new model, with the improved components all around, and thank god has the mount points in the corners rather than the middle of the sides, so you can hang it from two points and it won't spin.
Exact same experience here, but a different perspective on the reasons why, namely that soldering is not part of a standard Field Replaceable Unit and the successful resolution of such would be nearly zero. That said, I'll admit that the design of LED lights and the dead simple PCB makes this one of very few exceptions.
I'd caution strongly about running a device with it's cooling system compromised in particular, but really with any portion of it a failed state, at least not without careful consideration and heavy monitoring. In this design, each driver and fan are cooling a portion of the panel, but not to the exclusion of the others. In my device's failure, another quadrant of the panel is partially lit, but doesn't have a working fan blowing across the heatsink above those running diodes.
They'll tell you a variation of "your cell phone is now the FRU", and increasingly they'd be right. Just a few years ago we could still crack open a blackberry and change out a screen fairly easily.
If I was an authorized and approved repair center, I could likely get the board sent to me, but soldering on memory chips onto a modern cell phone's PCB isn't realistic and wouldn't be done by anyone. It's far cheaper to replace it than attempt to repair it.
I'm suggesting the PCB as a whole is the logical FRU,with LEDs affixed by an approved if not certified technician who has tested it as fully operational, and that is the expectation of the vast majority of consumers.
Anyway, my expectations aside, I'll report back once we've received all the parts and have attempted the necessary repairs. In the meantime my Mars II 900s are growing me and my cohorts some fantastic Cannabis in my Mars tent.
I'm sorry for that.Next time we will ask you if you need to send to our repair center first all of.
your girls are lush.
Hi KingSativa.Thanks for your help.
our new goods already arrived at our Canada warehouse
Your dream will come true very soon
i just need to ensure that all of our customer understand every changes we did for our light,so that they can be more confident to use it.
...you are good at editing
--but experts generally recommend 40 to 50 true Watts/squarefoot for best results, which works out to 160 to 200W for your space. Based on that the Mars300, at 132 true Watts is the better choice and bang for the buck. If you could swing a little more money, the 214W Reflector96, with its switchable veg/bloom modes would be give you more light and control, but costs more money.
