I was browsing thekrib
concerning the post
Color spectrum Vs Degree Kelvin??)
since I was planning on getting a 6x13W compact flourescent( yes,
thats 1x13W individual ballasts) for my 10 gallon, to upgrade.
The offering of bulbs are as follows
Now I could get an assortment, i.e. 2 of each color temperature,
but i read that plants photosynthesize best at under high red spectrum
lighting. So im concerned about selecting the best color temperature bulb
since I (think) i want to go with strong reds in my light selection.
According to the aforementioned post on thekrib, a 3000K temperature
will have very strong reds, and at the high end of the temperatures
such as 9000K, you have alot of blues. Does this mean that a 5000K
bulb has a roughly even mix of reds and blues?
THe primary question is what bulbs do I select?
Also as an aside, as a quick analysis between
bulbs.com versus AHsupply.com
2x13 watts at AH supply using the cheapest AHsupply bulbs
2x13 watts at AH supply using the $2 bulbs
2x 13 Watts at bulbs.com (using double 1x13 ballasts ) with $2 phillips
= $14 =
1.86 Watts per Dollar 0.93 Watts per dollar
at bulbs.com at AHsupply
If anyone can help me find even a stronger watts per dollar on compact
flourescents, let me know!!! Im always on the conquest to get the most
out of my money.
