Cheap Cree 60w Bulbs?

[Funkadelic]

Cree has inexpensive 40 and 60 watt bulbs on sale at Home Despot. They are 3500 and 5000k spectrum.

Can these be used for plant growth? Theyre very inexpensive and simple... thoughts?

(They're bright as fuuuuuuuuuuck)

Sure if you're gonna use like 10 of them per 1 sqrf ;) (60 Watters)

 

[Funkadelic]

Agreed. Thats 600w of LED for $50 .... makes sense right?
What kelvin for flower? The 3500?

This is supplemental side lighting for a room with 8k vertical bare bulb hps...

 

[Toaster79]

No, thats 50-60W of LED power. 600W would be if you used 6 100W incans ;)
If you're running a 8K vert room you should look into something more serious or DIY with LEDs if you're looking for a cheaper version.

Thanks bro for feedback. How about using these for veg? Theyre just so damned cheap!

 

[Toaster79]

Pretty much the same story. Get some 5000K ones like 10 and put a plant under. See how it works.

10? Man, these bulbs outperform a 40w actual CFl and way less heat. I use 3 per 2 sq foot

What bulbs exactly are you using/comparing? I'm really curious what even 10W LED outperforms a 40W CFL (not 40W substitute but actuall power)

Did a little digging and came across some data about those bulbs and if those are actually the same bulbs were talking about - 660W A19?, then those run at 13.5W for TW verion with low lumionus flux at only 800lm (60lm/W)
