The diffrent one is a cob with 246 true watt that is full spec .(the one i have is not a cob , would it matter ?) What are my 420 families thoughts on this . Mixing lights . Click my sign.

Mixing light sources doesn't matter. The only recommendations you'll get from here are for QBs.

Midpowered diodes can be incredibly efficient and provide a large light source surface area for better crop coverage.

Lots of people regret cheap lights, no one regrets a good one. It is worth the time to save the extra money and make a quality investment. The lights are the engine that drive the whole operation.
