Are you saying DO NOT get a Zoo with external ballast?after much research on commercial MV and MH bulbs as a source of UV, the conclusion is they are useless with out proper "FILTER" glass known as hard glass or specially designed borosilicate glass(much $) to filter the UV from the bulbs. without these types of glass, the UV from a commercial bulb would be dangerous levels of UV and was the source of problems with ZOO lamps external ballasted MH reptile bulb.
I have two megaray's 60 watts Zoo external ballasted and 2 megaray 70 Zoo megaray mh...they are more useful IMO as they give off a light that the plants want...mv has a horrible plant spectrum...also the externally ballasted lamps remain viable 18 or more months whereas the internally ballasted ones only 6-8 months...reason being is that the internally ballasted actually are ignited using a filament which adds lots of heat which in turn polarizing the glass quicker thereby dropping uvb production quicker...if they are still out of stock you can get an externally ballasted 60 watt mv but not a zoo model for a smaller area you can check this outno the external ballast is fine and the MV bulb is fine, its the design of their MH bulb that is dangerous, so dont get the MH bulbs, but they are out of stock anyways right now. i think they use the same ballasts for MH as MV, i dont kno i would have at look at the wattage for the MH.
anyways thought i would update prefer not to waste a new post so im gonna edit this one,

you have to write them for the externally ballasted 60 watters
they were 2 for $40 when I bought mine...I use it in my femming areas
do not feed the troll please! ^^^but guys, you'll save 60% or more by making the switch to incandescent!
Who can beat over 200 years of proven technology?
Not to mention, how much more american do you get?
With their amazing 3000k light spectrum,
they make great flowering bulbs.
They're super cheap too,
i've got a 900w incandescent grow at 6 weeks flowering myself.
Come on guys, what are you waiting for?
