Hi beez0404, I just checked with engineer, the SP we have SP200, this one is with MW driver, which can adjust the driver and then have the dimmer function, if someone is interested, can send email to us, we will ask the engineer shoot a video on how to do so, and send it to the customer.Is the brand new, state of the art Mars light dimmable? I just takes the right driver and you're done.
Always did a lot of research on everything, I like your way! And your right, the SP200 in fact can be dimmable but needs to change the driver set up. SP 150 cannot. I believe this won't influence the warranty. So no problem at all!In the video, the SP 200 utilizes the Meanwell ELG-240-36A power supply. According to Meanwell's specifications sheet, the letter suffix denotes whether that feature is present. If blank, "Io and Vo fixed." There are several possibilities, but A is listed as being "Io and Vo adjustable through built-in potentiometer."
Code:https://www.meanwell.com/Upload/PDF/ELG-240/ELG-240-SPEC.PDF
So, technically, the feature should be present on the SP 200 (the SP 150 uses the company's own power supply instead of a Meanwell in order to keep the customer's costs down, I think, but it appears that MH can work with the customer if he/she wishes to purchase custom products (for a higher price, of course)).
The only potential I see with actually using the potentiometer on the SP 200's power supply is that it would probably void the customer's warranty. After all, what can be turned down... could just as easily be turned up, lol. And the ELG-240-36A's maximum rated wattage is 240 watts, which is approximately 22.4% more than the listed wattage of the SP 200.
From the company's standpoint, it might make sense to remove the plug covering the adjustment screw and fill the cavity with some kind of resin, or to replace that plug with a more permanent covering, in much the same way that the carburetors on US automobiles back in the mid-late 1970s had their mixture adjustment screws covered. I hope they've got another way to ensure that the customer doesn't overdrive the product, though (or, if the customer chooses to do so, that it will be obvious that he/she did). Maybe one of those "anti-tamper" stickers or something, IDK. Because the ability to be able to turn the wattage down would be considered to be a useful feature by many.
A problem for the engineering department, I suppose.
EDIT: The implementation of such a dimming feature may depend on how the product is wired. I don't know enough about these things to know one way or the other.
Thank you for the suggestion, we use to make a survey, it shows a half like the short ones, and another half like the higher ones, I already forward this to our tent department, and they might do some change in future!Random comment: I wish you sold a 90cm x 90cm x 200cm grow tent.
Hi Gadfly, the Mars II is well know for its penetration, and the Mars II 900 can be suitable for the 3'x3' tent, not only for veg, but also for flowering. But you need to know that LED growing is kinda different from HPS growing, as long as we follow the right instruction, we will get better and better growing result for sure. Here below I can show you some pictures from our customers.^^^^
When I was tent shopping, the Mars 3x3 tent was a little shorter than what I was looking for. Also the 1680d displays two English measurements—40x40x72 in large print and 39x39x70 in the smaller specs print.
However, I am still light shopping. Here’s my problem, I’m an hps person. It’s what I’ve known works. I have lots of experience with hps from 400 watt to 1000 watt. It’s a very known tool for me. Ive used leds in the past as a tester and have never been impressed in regards to flowering. Great for vegging, not so much for flowering.
Fast forward 5 years and here we all are. Things seem to have changed a lot in the led world. So much so I’m thinking of actually going led for my personal 3x3x6 tent. The Mars 2 900 is what your website recommends and I have been considering giving it a try. My main concern is canopy penetration. In my experience with leds and flowering is that you can get some decent colas, and then everything under grows very weak.
Sooooo, is there anyone with experience using this specific model? Most of the successful journals I see use other led models and the only ones I’ve found related to the Mars 2 900 seem to be from less experienced individuals making it hard to gage the real world results of the light itself. Any help is appreciated.
I already forward this to our tent department, and they might do some change in future!
Sure again, thank you for explaining such clear! I will let them knows.Thank you for forwarding my suggestion. It would make sense to produce/sell a 90cm x 90cm x 200 tent, in my opinion, because you sell LED products which seem like they would work great in a 3' x 3' tent (3' = 36" = 91.44cm). The closest you currently sell is the 100cm x 100cm x 180cm tent, which might be a little large for them. The difference is 9 square feet for my suggestion, versus 10.764 square feet for your closest current offering. That doesn't seem like a great deal of difference, just looking at the bare numbers - but it "pushes" the reflective walls farther away, which could mean that light is lost over the "extra" space that would otherwise have been reflected back onto the plants in a useful concentration. The current tent's height of 180cm might, realistically, be a little short for those who use your stronger LED products (or who choose to use, for example, a 600-watt HPS), especially if they use five-gallon buckets, an average-height DWC hydroponics reservoir, or other relatively tall container to hold their plants in. When one allows space for the container, the LED panel or other light source, and at least a minimum amount of air space above the light source - and allows for the minimum reasonable distance between the bottom of that light source and the tops of the plants - it does not leave a great deal of vertical space for the plants.
That was my logic for making this suggestion. If you would like to pass the above comments along to your engineering department, so they understand why I suggested this specific size, I would appreciate it.
Again, thank you.
Hi MyDogSpot, welcome back! So nice to hear that the Mars Pro II Epistar 320 is working great! Will you also take part in our tester programme? If so, can you help post in this thread?It’s been a long while since I’ve posted to this thread.
SoI had to stop in here to provide some real world feedback and say that 2 years ago I purchased 2 of the Mars Pro II Epistar 320s.
Previously I was using them in 4’x4’ grow tents, and now as my sole veg room lights.
I’ve never had an issue with them whatsoever. No leds have ever burnt out.
I can do anything under these lights and successfully.
I’ve germinated seeds, grown successful clones, very happy with veg and great flowering under them.
I’ve had awesome harvests and hard dense buds that even the mh/hps growers love.
Even with So many led options, and with prices all over the place; I’m quite satisfied with the bang for buck these have provided me in a home tent setup.
Cheers!
