well, I replaced my 175w HQI's, and my RPE's went from stretching 3/4" to the light to back down to the 1/4". the bulbs I replaced were my first metal halide bulbs, as I got my hood last year, and I was surprised just how much brighter new bulbs were.
I thought certain wavelengths wore out in old bulbs, but didn't expect the brightness to reduce so much over time. wow! the more light seems to make my little RPE's happier.
MY QUESTION:
I replaced my 20k bulbs with 15k's, not only do I not like the new wavelength, but I hear that lower temperature bulbs diminishes color, even if they encourage growth. Is that right?
I'm happy with my old acitinic PC / 20k metal halide combo, will this combo be best for color?
The RPE's I bought from a seller here at RC are much more dull and drab than the pictures I saw, i thought the 20k's just weren't showing the true red.. but maybe not. They're not much more colorful under 15k. I wanted a more balanced display of color, I thought the 20k's were too blue to show nice oranges and reds, but now I'm thinking that's not the case.
thanks,
