ARKNOAH 3000W Growing Lamps Plants Grow Lighting

Great lighting

This 3000W light has 480 5W LED chips. The 1500W light has 300 5W LED chips. The 1500W light adds up correctly. 300 LED's at 5W's each is 300 x 5 = 1500W. But 480 LED's at 5W's each is 480 x 5 = 2400W...what what what? This light is advertised as 3000W equivalent lumens light. Same with the 2000W light. It has 360 LED chips at 5W's each. That calculates out to 360 x 5 = 1800W's not 2000W. I bought this light (3000W) because I wanted one like I bought 02/2019. That one was a 2000W light. The 2000W is fantastic for Vegetative Growth, more 480nM ~ 580nM, than the 3000W light I just bought from ARKNOAH 07/2020. The 3000W light clearly had a larger emission of RED light than the 17 month old ARKNOAH 2000W light. I placed these lights in two in two separate grow rooms and the 3000W light clearly had much stronger RED light presence where the 2000W light was much whiter which leads me to believe a much more balanced spectrum. I inquired with ARKNOAH twice about the RED shift and both times I got no place. Both responses from ARKNOAH did not address the issue I presented to them. Their responses totally skirted my interrogatives. Well bottom line the New ARKNOAH 3000W was not at all like the Older ARKNOAH 2000W light and I received no explanation at all from ARKNOAH. Since this light (3000W) produces more RED so great for Flowering Stage but not so great for Vegetative Stage which is my objective...so back it went. Confidence is not high with ARKNOAH and the Older 2000W light is clearly a different spectrum producing LED. ARKNOAH stated that nothing has changed with their Chips...mmm.

No thanks

Nice product for flowering

Plants seemed to like it in vegatative, but seems lacking after entering flowering. Alot of stretch compared to using hps. Par lighting off maybe. Surprised by the amount of heat it produces.
