This can be good or bad for plants…

Although it seems we would want a filament bulb because it has a linear spectrum (all color equal) unfortunately filament bulbs are very wasteful. They [Ushio] have anything between 3000k and 6000k between 80 CRI and 95 CRI And you have a lumen output. I just use Ushio as an example because they have a wide variety of bulbs, T-8, T-5, T-12, MH/HPS etc... and very good with specs, and a smaller company compared to Philips or Osram which have thousands of bulbs...

Just check out the various specs, anything in between 4000-5000k is pleasant to look at, and 80+ CRI is great... 90+ is awesome... On the PDF they even have graphs of the output peaks if you want to get crazy, but it would be hard to guesstimate the PAR active energy, and it's been my opinion that 4000k bulbs work just fine for all around growing. HPS is just ugly to look at, although extremely efficient, so you get a bit more bang for your buck with HPS, I have my dad a little 250w HPS bulb I made out of an old down light, he keeps his geraniums etc... healthy during the winter.” - Ocelaris, Senior Member
