OK, when it comes to some topics, I can handle myself pretty well, but I've run across something that I am not sure about.
We are moving the our church office from a room with 2 large windows on the east and south exposures and moving into church basement with 1 smaller north exposure window.
It's been strongly suggested to me that to replace the amount of daylight we used to get we should use "full spectrum florescent bulbs" rather than regular bulbs.
Now, I have seen the difference that full spectrum lights can make and I think in this case they will be worth the extra expense. For those unfamiliar with dealing with church groups, they are notoriously tight-fisted with money.
Someone has said that regular florescent bulbs at 65K are "even better than full spectrum" because the full spectrum bulbs are only 5K. Now, the 65K bulbs don't say "full spectrum."
Is there a difference, like I suspect, or is the 65K bulb going to give the same "daylight?" Thanks for the help.
I have never seen the benefit of "full spectrum" lamps. They are WAY over priced IMO.
I use T8 741 lamps in all new work and my customers love them. These are 4100K.
Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.
