Lighting So many questions .

[hecno]

Great info guys , I will have a number of questions , but the main one that stumps me at the moment and I can't seem to find the answer for --- how do you work out the number of cobs for your room size , I have a 4 foot by 4 foot area .

Think it should go like 25w per square foot

Think it should go like 25w per square feet

Would that be rated or actual?

For example, my tent is 200 x 300 which calculates to 65 sq ft.

65 x 25 = 1625

Would that require 17 x 100W COBs?
Or 30 x 100W COBs @ ~ 55% efficiency?

Is your tent in inches or centimeters? The 200 X 300?

Centimetres.

So 2m x 3m

Centimetres.

So 2m x 3m

Based off that then I think you've got it.

He he - yeah - except for the answer to the question.


Is the 25W / sq ft the rated W or the actual W?

I.e. 17 x 100W COBs ... OR ... 30 x 100W COBs @ ~55% efficiency?

 

[dcat0921]

I would think actual watts but I could be wrong.
Either way it sounds like a ton of lights but I would think its actual watts.
Hopefully someone else will verify...sorry I'm not much help

Yoz, go check out the DIY LED thread, and ask our Main Man Arty Zan, he'll get you squared away mate! :smoking:
