First profile is from my "Ghetto" heli rack. GE Sunshine T8 36w bulbs, these are a very high CRI bulb that was known as the "Chroma 50" for many years. They are an inexpensive bulb that have grown plants well for me for many years and can be found at any big box building supply store (i.e., Lowe's)
Next profile is my main Heliamphora rack, these are Giesemann Aquaflora 54w T5 These have been my bulb of choice for the last 5+ years
you have to disregard the differences in visual intensity, that simply means I was closer to one bulb that the other. Mainly look at the spectral pattern and relative energy levels from one wavelength to another.
There is a little bit of an "art" to getting just the right amount of light when taking these measurements. It's very easy to oversaturate, my Chroma 50 profile is oversaturated.
