Bests & Worsts Reviews from Amazon

So I am worried because this is a 2k watt light for cheap with IR and UV. While I dont know the light measurements since my light meter broke. I ordered 4 of these to replace 2 HPS 1000 Watt lights, so on paper I went from 2k Watt to 8k Watts. It is still early to tell if I am saving on energy but I am pretty sure I will. On a daily graph of energy I use to use 84 KWH per day with lights on 18/6 I now I am only using 41 KWH's. So for the last 2 days I have used 41.2 KWH and 42.8 KWH. So already I see a HUGE different in amount of energy used. Now onto the lights. I wish I had my tool to measure the light levels on this. on that side I can't help, but I will say the plants have EXPLODED!!!! I grow indoors and in a 12x14 room. No CO2 burner nor CO2 bags, but CO2 in the room runs from 650 to 700ppm which is more than enough for my medicine. So I have noticed that yes it does not penetrate like HPS does, BUT if you grow your harvest correctly, If you are a Fimmer or Topper and use Super cropping correctly, this light will do wonders. So I am a big person on writing down levels of temp, co2, ppm of nutes, and even measuring the plants. Yes I am that detailed lol, yes I have OCD. So during the time since seed, my plants grew 54.3 inches in 2 months, over the last week they have only grew 2.1 inches up. After hanging the lights they have already grew 1.4 inches in 2 1/2 days. I dont know if its because of the UV and IR, since my old 1000 watt hps hoods were double ended and had glass which cut the UV and IR out. The heat from these devices is VERY minimal, I have a small 12000 BTU AC and room is set at 75 degrees at all time, and its only on 4, the heat difference is HUGE compared from HPS to LED. I use to pipe my HPS with a CFM fan out the ceiling, I took it all down and put these in and the room holds CO2 way better since the fan isn't taking it out of the room, and way easier to control temp So far I am very very pleased with these lights, yes they are cheap, I am unsure on how they are so cheap, but I have had NOTHING but good results with these lights. I have switched to 12/12 now and will give more update on advancement of the plants and power consumption. So far I love this product and will be buying more. I want 8 of these in a 10x10 tent with a co2 burner. But so far these were worth every penny!!!! Also make sure to buy glasses, these are SUPER bright and hurt your eyes without glasses haha. I forgot to grab them, went in and started working and my eyes were like a strobe light when I left the room.
