8U and Reflector Questions

Hey guyz & grrlz!

Dumb question (like all my questions).

I have 200w 8U CFL and a economy white horizontal open-end reflectors.
My reflector hood has 2 socket positions. Upper & or lower.
I am using the lower.
I figured for heat dissipation from under hood, and so my plant are not right up in there.

With the bulb horizontal, the top U's of the bulb seem like wasted lumens.
The top U's upwards lumens have to go 4 or 6 inches before they can reflect back.
And the top U's downward lumens, well, they just shine on the bottom's upward lumens.
LOL.

Should I glue mylar to the inside of the reflector?
Will it help bring more lumens downward then white will?
Or should I buy a vertical reflector?
How to maximize my energy used to go towards my plants with a 8U CFL?

.............Anybody?

Thanks!

sry man i dont know what an 8u reflector is...

ahh they suck man ... 6000 lumens for 200 watts ?

If you the most crappy reflectors with marks and scrachtes, yes use your mylar i dont see why not.... ^^

If u have a reflector u dont loose lumens u gain them...

sorry that noone help'd ya

Well what u wana do make a 90° curve'd metal shiner

that would be an asset for every grower good thinking batman

but i guess the heat couldnt escape and you would have to have your room cool'd ....

thats what happens with those cfl's !


and is this the cfl u have ? or talking about... Detail

Pro-Type

^^ this is what i got 600Watt one 90'000 lumens ! I want to plug it in

You could try putting a sheet of mylar over the actual cfl bulb (but not over the ballast). I did this and the intesity goes right up! Beware of the extra heat build up though, don't do it unless you've got good vento! %D

yes.
Similar in shape.
I have a Future Harvest Development 200w (14,xxx lumens), and a Growrite 250w (16,000 lumens).
