A very stupid question!! maybe not so stupid....
Hello everyone!
Ok, this Saturday, I`m going to buy my new fixture for new lighting! I have decided that I`m gonna buy 6 shop light fisture, two shoplight with 4 tubes for each shelf of my unit. I have also decided that I`m going to use 2 40W 48 inch of Cool white and 2 40W 48 inch warm light because coll whit have more blue light and warm more red! Here is the question: Does it matter the order I`m going to install the tubes! I mean should I put : Warm, cold, warm cold or Warm Cold cold warm or Cold warm warm cold or Cold warm cold warm I told you that can be a very stupid question! thanks Claude -- Claude www.picturetrail.com/phalguy Remove NOSPAM to reply |

s.com... Here is the question: Does it matter the order I`m going to install the tubes! I have my tubes installed CW-WW-CW-WW, and I also try to shuffle the plants around when I water for a little divertisy. --Matt |

Thank you Matthiew!
Do you know hom many feet-candle you get with 4 tubes like that? Does the tube generates lots of heat?

Claude,
Certainly not a stupid question. Although all sources of light produce some heat, fluorescent tubes produce less heat than normal incandescent lamp (and that´s the main reason why they are more efficient) However you have to take care of where you place the ballast or "reactancia". If you have only one shelf you dont have to worry about temperature place everything above the plants. Regarding the order of the tubes IMHO there is no reason to worry about. What I think it does matter is the number of each kind of tubes that you will combine ie 2C + 2W or 1C+3W or any other possible combination. You could also calculate what would be the feet candle received on the shelves but you have to consider a lot of things (lumens provided by each tube, type of lamp, color of the walls, and of course the distance). Also the tubes only provide their nominal lumens when their are brand-new. Few days after that the power of the tube is not the same as the first day although your eyes cannot perceive that. So, I would recommend you to buy a light meter. Hope have been of help Regards Fernando Buenos Aires - Argentina PhalGuy wrote: Thank you Matthiew!
