Hi!
I cant tell you where to buy a plug&play T5 light panel, but I can tell you that its very easy to construct it yourself, even if you are not a professional electrician. It is also much cheaper and performance vise just as good as the manufacturey built ones.
For my micro closet grow with a surface area of 90 x 50 cm I use a diy light panel with four 39W Osram LUMILUX T5 HO fluorescent tubes that are driven by two ECG ballasts also by Osram. These tubes are 849mm long and each delivers 3500lm or 82lm/W. With a lifespan of 24000h ( rated lamp survival factor at 16000h:0,97 and at 20000h: 0,85 with a 10% decrese in luminus output ) so I dont think thats too bad, they go a long way.
You can buy all the components you need at any decent electric components store (central Europe), and they are not at all expensive.
The ballasts I use are Osram quicktronic proffesional 5 (each drives two tubes)... price: 19eur with tax.
The tubes are Osram T5 HO FQ 39W, 849mm... price: 3,8 eur with tax.

Ive made my own reflectors but you can buy them at aquaristics shops for around 16eur/piece (and these are very nice ones specially designed for T5 lights with efficiency rated at 95%).
http://www.reflekta.com/ ... this is their website... as it turns out they make they make comlete light modules as well, not just reflectors.
No need to go DIY, but anyway...
So a two lamp unit with reflectors would cost you around 60euro + some extra materials, like wire, switches, cables, and some metal or wood and some screws for construction of a frame.
My light unit costed me around 200euro but that was many years ago, now it is much cheaper, the prices above are the current ones , and I have diy reflectors which are the most difficult part to construct. Dont know how efficient they are. But they cant be too bad, since these lights (156w alltogether) produce just over 100g of bag seed staiva buds, or 0.65g/W. And the best Ive got was 143g with NL cuttings, and thats pretty close to 1g/W. I grow in soil with Sog method.
And this unit has been in use for almost ten years now with no issues whatsoever (replaced the tubes only once) I do three to four grows a year and use it for flowering.. and also for clone propagation for my guerilla gardens (for this purpose I originally bought these lights).
So if you are up to it, you can do it yourself (its really very simple, you just have to wire it up exactly as the diagram shows you) or have a friend who is more at home in this field help you. You will save some money aswell.
Or you could go LED.
Ive been looking at some LED street lighting panels by Osram, and they seem very nice, but too pricey for me at the moment.
PrevaLED copact module delivers 6000 lm and consumes 47W thats 129lm/W, and it costs around 110 eur, and their strongest modul delivers 10,000lm for 78W, thats 130lm/W and costs around 200eur. But the lifespan is very long at 60,000h. The color temp. is 4000 or 5700K... so this should work very nicely indeed.
Im really tempted by this LED lights, but cant bring myself to making this expence since I am very happy with the system I allready have, but If I was starting from scratch I would definetly go with these. Cheers.
