Random review of the two products from Amazon below:
“I bought this product after seeing the PAR chart which shows the Mars Hydro SP300 exceeding light output of a 450 watt competing light (I own that light too)
I was initially skeptical on how a 300 watt light could exceed performance on a 450 watt light. My worries proved true. Turned up to full power this 300 watt light isn’t nearly as bright as the 450 watt
The light has maybe 2 x 4 footprint whereas the 450 watt light is closer to 3 x 4. Because of this most plants on this side of the 4x8 are flowering under 18 hours of light. The plants on the side with the 450w are healthier, more vigorous and still in vegetative growth. This light purchase will end up costing me about 250 grams or $2000 in lost harvest weight
My 450 watt led was $150 less. The cheaper light seems to outperform the SP300 by a large margin. I feel like the more expensive 6500 model might be nice, this one can only be used as supplemental lighting
There were also some quirky manufacturers issues to point out which I have attached pics of. There is a couple feet of cord between the driver and switch that I don’t understand. It’s almost like you could remove the driver and mount external to tent. There is no indication in manual why it would be there so I just taped the extra couple feet of cord to the ceiling of the tent.
Also, the mounting brackets are super cheap and do not have holes, you wedge the cheap bracket in to the heat sink. To me I was shocked. This isn’t secure at all, someone could barely bump the light and it would risk falling to the ground
It would make more sense to add a bracket with holes on the outside of the driver and switch. Then the light would be sturdy
I will be trying this light for a dark spot in my high pressure sodium room, might end up returning, still have 30 days to decide”
