Many folks here in the US feel exactly the same way. Sometimes it is because 
they do
not know where (or how) to look.

The same thing happens when we go to the big chainstore outlets here.
Lighting is a total mystery to the clerks, and many will give misinformation
if they don't have real answers.

OTOH, I think AH Supply can ship internationally, and it is hard to beat 
their mix
of CF and reflector designs, at any price. Theirs are quite low.

Amano is reported to use a lot of "Cool White" fluorescents, for the 
appearance they give.
Most folks here opt for a better compromise with growth, so tend to mix 
phosphors or go for
lower-lumen broad-band sources that are less green but look less bright.

You need to contact the distributors that deal with big stores, hotels, 
etc., and get away from the retail outlets for lighting sources and 
information. Here we have Grainger as well as major lighting distributors in 
major urban areas. The LFS and Home Depot are nearly worthless, unless you 
know what you want and they just happen to have it. I would imagine that the 
situation is similar in India. We may have more meat counters (the primary 
excuse for making Chroma 50s) but the specialty bulbs and tubes for 
commercial lighting just usually are not available at the local dry-goods 
store. [The local grocer sure knows where to get them, though.]
