I discredit any "side by side" using open ended wing reflectors. Especially when held together with duct tape

Regardless it could be open bulb.the light is not in the reflector it's in the bulb and the cobs are still killing it.the growth directly below the bulb still cant compete.I discredit any "side by side" using open ended wing reflectors. Especially when held together with duct tape

It's a watt for watt comparison not an equivilent.
If it was close I would say well maybe but not.i still love cmh but I think the cobs are better.ive ran them both through flower over smaller scrogs and no comparison

HID is dead tech. LED is the present and the future.

Reflector or not the growth 15 inches below the cmh bulb still cant keep up with the cobs.

That’s kinda what I meant. 700 watts of led is about 20% more efficient potentially than 700 watts (if it existed) of CMH. And it’s only 630 so the cobs have quite an advantage.
I wasn’t arguing about which lights are better. They are tools. Tons of variables in choosing them.

You still say that but I have low ceiling height and cold rooms and hid bulbs help heat my house. If I tried to channel the same wattage in led I would have way too much light for my present space.
And I understand I need to increase canopy temps from the 76 I have trouble maintaining now in dead of winter.
