Re: VHO vs SHO

    VHO are the same as flourescents only of higher wattage and SHOs are put 
out by Perfecto and is their brand of compact flourescents.  I don't know 
about "spot" osrams but the SHOs house 2 55 watt compactflourescents and are 
very bright.  I have 2 on my reef aquarium and it does very well.
