I just don't get it :what: Surely if the lamp is the equivalent of 50w then that should be plenty of light? Its also the correct colour temp.
Some sources claim its WPG to measure if you have enough light, others say that is outdated and its PAR that counts (i can't afford a meter). I also read that Lux matters and that the real measure is PUR because that is the amount of light not only available but usable by plants. My head hurts from all the reading.
I really want to use this bulb because its very energy efficient. I suppose i will just have to see how my eleocharis does and change the bulb if it doesn't grow.
Ya..the color is quite yellowish but I kinda like the warmer feeling as the tank sits in my bedroom. It's probably not the best for the plants, I am sure ur 6500K should work better for plants
I have some limited CO2 (around 1 bubble per 3 secs) and some plants are pearling/breathing out streams of bubbles.
So I believe yours should be good enough. O well u can always get another table lamp or just get some stronger light bulbs! I found it hard to find the right color temperature tho as most LED light bulbs are in the 3000k-3500k range for indoor use
