Three SP250 can be chained together. 

Yes, using a screwdriver to dim.

There is a button on the driver, using it to dim. 

TS1000 is better. Because it is more powerful than reflector 48. And it is new quantum board design. longer lifespan. 

There is no IR for TS1000

The TS doesn't have switches for veg and bloom, but the light can be wattage adjustable. You can use the light for the whole grow cycle. 

Hi Sir, the TS series are dimmable, you can use a screw to adjust on the power supply. :) 

Hi Sir, the TS 1000 is suitable for 3x3 during veg, and 2x2 during flowering, so you will need 4 of them to cover your 4x4 tent; Or you can try two of the SP 250 or TSL2000. We will have TS 3000 that can cover the 4x4 space in two month time as well. 

the screw driver with the similar diameter as the hole on light, get the screw driver into the hole, it will make the light dimmable. Check this video , it show how to dimmable the light. :) https://www.youtube.com/watch?v=vsOvakBPJdY

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

During seedling: 18/6 or 20/4; above 30'' 
During veg: 18/6 or 20/4; 18~24'' above canopy
During flowering: 12/12; 12~18'' above canopy

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: solutions@mars-hydro.com 

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. 

Hi, TS cannot be daisy chained 

During veg, it can cover 3'x3'; During flowering, it can cover 2'x2'. 

The maximum power is 150w, if you want bigger wattage light, you can consider our TS 2000. :) 

100% will be perfect for flower. :) with right hanging distance around 12~16'' above your plants will be great.:) 

Hi our TS series can work at 100~277v voltage, as long as the plug is the right type, you can use the light at any voltage without any problem. :) 

Hi including the package, you will find a TS 1000 light, the power cord, the rachet hangers, the normal hangers, plus instruction and warranty manuel. :) 

Hello, TS1000 the coverage is 2x2 at the bloom stage, 3x3 at the veg stage. If your room is 4x4, I'd lie to recommend the TS 3000 for you. We could ship it from our China warehouse to Kazakhstan. 

TS1000led power cord is not long enough to move driver outside 

You will get: light+power cord + steel hangers + rachet hangers + instruction and warranty manuel
