Flowering with Cree bulbs

[captainmorgan]

Is that one of those Cree LED incandescent replacement bulbs I see?

That was 5000k induction with 630 nm and 660 nm T5 HO and some Cree 2700k bulbs alright.

Doesn't look omnidirectional like they claim

Cool use of allot of leds, at half the power consumption of cfl's! Thumbs up!

Hi captainmorgan,
Great thread. Why choose 9.5 globe bulbs over flood lights. I am considering the light below:

At the beginning of the thread you argued that the globe bulbs you are using put out more lumens from their sides. Why not use the flood lights and direct all the light on the plants?
I am not criticizing you in anyway. I don't have much knowledge on growing with bulbs and I value your opinion and advice.

At the time the bulbs were more efficient than the floods.

Thx for the reply. Are the floods I linked more efficient. Basically, if you had to start from scratch, which would you use and why?
I sincerely appreciate your time and input.

Bump for this answer
