I believe 860 refers to 6000k color temp. Should be okay for plants.

Do you happen to have a list of what the numbers corresspond to what colour temp.?
Corydoras: 2 x adolfoi, 1 x agassizii, 5 x albino aeneus, 3 x arcuatus, 4 x atropersonatus, 3 x axelrodi, 6 x axelrodi variante B, 4 x caudimaculatus, 5 x duplicareus, 8 x goldlines, 3 x kanei, 3 x loretoensis, 6 x melini, 4 x panda, 6 x schwartzi, 3 x similis, 4 x sterbai, 4 x surinamensis, 5 x trilineatus, 4 x tukano & 3 x zygatus
RIP 1 x adolfoi, 1 x albino aeneus & 2 x panda
My friend pointed this out to me on OSRAM PL lights at hardware shop yesterday :
865 - 6500K (printed on box)
827 - 2700K (printed on box)
So, I'm assuming we can just drop the first digit '8' and take the last 2 digits as the color temp.
Philips label their PL lights as 827, 840 & 865. Hope this assumption is correct. []

Chua,
You're right.
Joe,
Recomended lights temp for planted tank is between 5500K~7500K. So 6000K should be OK.
The '8' in 865 or 827 represents the colour rendering index (CRI) of the FL tube. The CRI of '8' is between 80 to 89 [2].
The CRI of natural sunlight during noon time is 100. When an object is illuminated with a source of light having CRI 100, the object will look like what it is supposed to be in its natural colour [1].
