I bought a digital light meter a while back ago and decided to see what readings I got on my lights in my new orchidarium....I would assume that the lights would be suitable for orchids being it is an orchidarium......this is what I get....
3000 FC is the highest I can get to the lights....but that would mean my plants would have to be smack against the acrylic glass....doesn't seem strong enough to me for my Cattleya's......hmmmm.
And at the bottom where I have my phal's (which I just burnt outside) it reads around 300 to 500 FC.
I have read that bright to highlight plants need 3000+ FC to bloom.....I have so many bright light orchids that I don't know what to do.
The bulbs read Sylvania Delux L 55watt. I have 3 fixtures with 2 bulbs each. Each contains a warm and cool bulb.
According to the Orchidarium Inc.'s website I am supposed to have six 21", 4800 lumen, high intensity, bi-axial lamps.
I know that lumen and FC are different measures of light, but my meter only gives me a choice of LUX and FC.
Any suggestions or am I just over reacting....I want my 'chids to bloom for me someday, not just grow!
Here is a link I found with the specifications of the light bulbs:
FT55DL/830/ECO - Sylvania 20590 - 55 Watt - 4-Pin - 2G11 Base - Compact Fluorescent Light Bulb
