I just bought this thing from a facebook fish-group auction... Gee I hope it wasn't a mistake :eyesmoke:

I haven't laid my hands on it yet but the description they gave was:
Aqua 1 5ft metal halide aquarium light with timer. 3x150 watt lights, 4x blue PL lamps. Includes hanging kit. Proven to produce excellent plant growth in both fresh and marine aquariums. Cable length 3m.

[FONT=lucida grande, tahoma, verdana, arial, sans-serif]Now what i'm [/FONT][FONT=lucida grande, tahoma, verdana, arial, sans-serif]going[/FONT][FONT=lucida grande, tahoma, verdana, arial, sans-serif] to use it for is a sliding door walk-in bedroom closet. Part of the light will cover a mother plant and the rest will be for rooting the cuttings then vegging for the first 2 or 3 weeks before being put in another bigger tent to veg a little more then flower.

As for globes... that may be how i've f-ed up. I don't know what connector they have on the globes but hopefully what ever type it is has the right spectrum for vegging

Ok I have done some googling and it seems to be an Aqua One mg-1500
The globes are double ended rx7 connectors and from a search it looks like I can get them in 14,000K, 20,000K, 30,000K & 40,000K.
I'm currently using a 27,000K cfl for a mother light so i'm thinking 30,000K is the closest and most suitable to growing (lands plants not aquatic ones and fish..)

The set up also has 4x 24w PL fluro... what ever that means + 2x 17w
Most likely i'll not use to fluro's. They are only in it as a fish light to add a more interesting light colour.

Over 100 views but no one comments... So i'll comment on my own post.

I've realised that i've completely muddled up the light spectrum's.
To start with I didn't realise that the numbers I was looking at have an extra 0 in them compared to grow lights.
Second, I didn't just mistakenly say my cfl was 27,000k instead of 2,700- it's actually a 6,500k!
I keep mixing up which one is red or blue.
So the lights I talked about are no good because they start well over the ideal 6,500.

On top of this- i've since been given a little more info from the seller and it turns out that the bulbs are screw in, not double ended. The screw in ones are so much more rare online to search for.

I'm still not entirely sure what screw socket size it takes but i've found a 6,200k that's e40 and also a 4,200k in e26.
It seems like there are also socket converters I could use.

Anyone care to make a comment now? Maybe someone wants to speculate whether a "6,400k" light that's not purpose made for growing will deliver the right spectrum?
I don't know much about it (clearly) but I've seen talk that it's just an averaged number of the light in general and doesn't tell you the exact details of what wavelengths are getting what intensity.
