Trocal MVP Bulbs

[A M Moore <andy at ascot_u-net.com>]

I have been using the German Dennerle TROCAL (Contra-algae) Mercury
Vapour 125 Watt bulbs for the past two years. Yes I know they are now
outdated and a 175Watt 5500K MH unit would be preferable !

Does anyone know:-

1) Colour temperature of these bulbs (Kelvin)

2)  CRI ?

3)  Why my last batch seem different to the previous batch - the
number on the bulb is now different & they SEEM to be more yellow ?
even though the bulbs still say Trocal 125 Watt on them ?

Any help would be appreciated.
