150HQI vs 175 Mogul

[banditpowdercoat]

OK, which would win? Coralife 150W HQI pendant

Or a Mag ballast 175W Mogul base? The Mogul base at present is a lamp shade style pendant, but even if it had say a U bend reflector?

I got both now, but the HQI I think the bulbs are old, like a couple years?? doesnt seem very bright
