The CCT shown on the chart I posted is how the bulbs tested in real life, not what the manufacturer claims. Sanjay did all these test with some elaborate equipment and posted the results as they came out. Some of the higher K
bulb show 0 CCT because the software he used couldn't decipher the result of those bulbs.
My bulbs tested out at 14.5K and they are a crisp white with a very slight hint of blue.
The Hortilux Eye are Iwasaki bulbs (made by Eye Lighting
), but they are in the wrong color spectrum for a reef tank with a name referring to horticulture and a 4200K (4K in relation to 15K aquarium bulbs) rating. Even the spectral chart for it shows it real high in the yellow range.
My Iwasaki bulbs, MT175AQUA2/HOR,
are listed here.
