Hi all of Mars Hydro lights are plug and play design, you don't need to buy other ballast or reflector to make it work. :) 

Hi one of the TSW 2000 is suitable for 4x4 during veg, but if you use the light during flowering, it will be only suitable for 3x3 area. You can try two of the SP 250 or TSL 2000 if you are looking for lights for 4x4 for whole cycle. 

It is customized UL listed driver, not a famous brand. :)  

Here is a reference video instruction to help you, please check: https://www.youtube.com/watch?v=vCfkz4EkbL8

The TS series are no fan design, so the panel needs to release heat itself. We are using all aluminum meterial for the light body, and all the material are anti-fire, over 90% of the components are UL listed, so the light won't catch fire. Also the heat is under control, won't influence the lifespan of the light. Please don't worry. BTW, the whole room temperature won't increase too much. If you don't like the heat of the light, you can add one small fan above the light, it will help a lot, also during winter, it will not be a problem as well. 

TS is not water proof, please make sure to clean the light now and then in order to ensure its longer lifespane. 

Hi TS has two connection side, one is for the power cord, another side you need to plug in to the panel aka pcb board. Please check if you have plug in both sides. If both sides is connected, the light shuold be on. If both sides is connected and the light is still not turn on, please email us for warranty: [email protected] 

The TS series is all aluminum for heat releasing purpose. But at the same time, the alunimnum is soft and easy to change shape during shipping. So the panel might change a little shape when you get it. But they will also be easy to use a hammer or something to return back shape as well. We are also keep improving our package to avoid more of these happen. Hope you can kindly understand. 

The TSW is the product SKU, the "TS" means Traditional Light Substitute, "W" means the "wide", because we also have TSL, L means "long"

Hi, TS cannot be daisy chained 

Normally we suggest keep the humidity within 50% - 70%, they cannot handle the moisture, so pls not make the grow room so much high humidity .

Hi Stephen, 

Thank you for your message and concern.Please kindly refer the following details to hang when different stage.Veg: 18''-24'' Flower: 12''-18''.

For the wattage, please use the formula to get the results.Veg: (21--30W)*grow size, Flower: (30--35W)*grow size.Then you could get the wattage value you will need.

Hope this is helpful.

Hi Sir, you can get from 25% of the light to 100% of the light wattage, which is around 75w the lowest. :) You can use a screw driver to adjust the wattage on the driver accordingly. :)
