Car HID 3000k lights for flowering ??

They gotta work better than CFL ??

The HID you mentioned has 85 lumens per watt.
A 250w CFL gives you about 60 lumens per watt.
The question is, with the extra heat and the fact that these CFLs give out 100% PAR and the HID does not, which is the most eficient?
I really don't know the answer. Maybe someone else does...
The light you have in mind would work. I don't think it matters that it's a xenon light, since it has the right spectrum (3000 K). That is good for flowering. You need like 6400 K for veg. It also seems very eficient, but that depends on how much heat it produces.
Maybe someone else has some experience with this type of light....

setup & weigh up the difference,

It would be an interesting experiment though... Are you going to start a journal?

Anyone tried using xenon lights for a grow, the phisics seems to suggest that they would work, a single 35w bulb gives out over 3000 lumens so for a small growing are I rekon they would work well, any thoughts on this ? They are cheap, efficient and bloody bright.

Start a grow and a journal and I bet you would get a few subs to follow along.
I would sub to see how good the grow went and if it did well I might try useing them with a 12 volt converter to see how well I saved on Electric Bill

Ok the challege has been thrown down as soon as ive popped some beans ill veg/flower a plant or 2 under HID 6000k/3000k(35w) & CFL 6400k/2700k(250w) this should be interesting
You caught my interest

I have two pairs of 3K HIDS for my car laying around, they seem like they could work, besides the whole heat issue. In my car you can feel the heat coming off of them without touching the lens.
Get a small fan blowing on/over/around the lights to keep the plants from burning

edit: after further research it appears they use various salts in the car headlamp xenon arc lamps which boosts the lumen output by changing the spectrum. The total photonic output is still relatively poor for input wattage as it is with all xenon arc lamps (when compared to the most efficient technologies, anyway). Apparently their major advantage is that you can make very very very high wattage lamps... get a 12kw xenon arc lamp and you should be able to grow some serious shit.
