Grow lush HPS lamp/Digi ballast- good, bad or indifferent!?!?

Greetings to all and sundry ,
I have recently aquired a new 600W HPS Ballast (old skool magnetic) & Globe via EBAY - its a Grow Lush (brand) for $100 bucks (120 delivered). The ballast claims to be "High Output" and the globe claims 20% more light than standard HPS lamps - which on the surface seems to be all well and good.

My doubts begin when reading the box the globe has arrived in, it reads:
Natural light alternitive for professional growers
24 Hour daylight alternative
20% more light
long life ..... blah blah blah...

"24 Hour daylight alternative" & "Natural light alternative" - do you peeps think that that means it would be inadequate to use for Flowering (& maybe even not all that good for veg)??

It also seems to run really hot too...

Does any one out there have any experiance with growlush equipment? in particular the globes?.

O yea, i almost forgot- i can grab a growlush digital balast for like $180, any one used em??
Generally speaking is it worth ditching my ancient 400W magnetic ballast and upgrading to the digi??

OK have just managed to find (what i think are) the stats on the spectrum provided with this globe...... does it seem suitable???

Hey Bazza, How ya doin ? I suspected Grow Lush were cheap crap and i was thinking of buying some of their HPS gear - not now, will go the extra $
Bought the 100 watt CFL kit at start of year and i have had nothing but failure and disappointment. Anyhow don't think CFL's are any good if you are serious, lession learnt. The reflector didn't even look like the one advertised.
