Recently, many people have asked how to extend the power cord. It may be because the weather is getting warmer. Please PM me and I will send you the parameters of the cord. 
You can go to your local hardware store or eBay buy. Regarding the waterproof connector of the extension cable, someone asked me what it looks like. Below is the pictures of the waterproof connector.
And extending your cable yourself wouldn’t make the warranty invalid no?

As long as the extending follow below specs, it won’t affect the warranty at all.
The minimum outer diameter：7MM 3*18AWG 300V 105℃ SJT VW-1
Conductor： Pure copper insulation、PEPteflon
Color：white、black、green
How’s Mars Hydro present shipment time in recent situation? Does recent case affect Mars delivery time?
If you live in USA,CA,UK,DE,EU,RU,AU, it won’t affect at all, we have a local warehouse there, and stocked many before.
If you live in other countries, that items need to ship from China, to avoid any more virus spreading, we are suggested to work at home, thus, the shipment will be made in 10-15 days later.
Get that in WRITING from the Company, on their letterhead before doing anything!
Always play it safe…employees come and go…

@Zoey hey do you guys have any details on the drivers that were used in the 2015 series 900w lights? Was mainly looking for make/model or just efficiency % of the output. I got the amp/voltage from the label on them already

Internal dimmers are too coarse for a decent adjustment imo. I prefer the drivers with external leads (like the Meanwell “B” type) , on which to attach a dimmer Potientiometer.
BTW: Last time I needed to buy pots…the 100 ohm ones were like 5 for a $1

Huh?
If you mean the pots and leads…They are low voltage.
Even if you wire a pot backwards, the worst that will happen is that the dimming function will be in reverse…NO damage to anything.
Another nice thing about having external leads, is that you can use an Arduino controller (pr-built or DYI), to do all kinds of things…like simulating a sunrise or sunset.
Not this exact model, was probably the series before, they didnt have “mars hydro” etched in the casing. I cant get the link to the aliexpress page anymore, i bought them back in 2015. “2PCS Marshydro 5 Watt LED Grow Light 900W Full Spectrum For Flowering” was the original item name from my invoice.

this was the original store page http://www.aliexpress.com/snapshot/7018583321.html?productId=2051401528
It doesnt exist anymore (obviously). Its ok if you don’t have any of the info, figured I would ask here anyway! I’ve had these lights for years and have recycled the drivers to make new lights from them rather than waste the parts
Thanks for your info., cannot open it. Can you send me a picture of your item? Let me confirm which item have you purchased from us, pls?
