Lighting Cobshop.net info, questions and answers

They do not have lenses but the cob holder I use does have a small reflector built in. 1/4 inch, it does make a difference. In a tight space I can use a different holder. I can also make a lower wattage cob. It will come out to around 40 watts vs 55.

The best thing you can do is train the plants. Less plants needed to fill the space but plant ties will help keep the plant low and flat.

Appreciate the reply, but I meant to say reflector, not lens. Though much of your answer still applies,

I don’t recommend the reflectors unless their is plenty of height. It is removable if you do decide to use it.

As I assumed. Thanks.

It depends on which cob. Theoretically you can run 4 36v cobs off this driver. It will turn on and work but my concern is for how long. I don’t have any evidence of this but I feel the harder the driver has to work the less likely it is to last. I’m sure there is someone who maxed. Mars driver out and has ran it for 3 years but I can say I came close to the max a few times and they didn’t last long at all.

Yes I agree with you and which driver would you recommend to run 6 1212s I'm going to build a frame for them and put it in the middle of my tent it's 34/34/58 and I'd like be able to run my fans from the same driver if possible..Thanks for all the help and all the headaches I cause you on here...

If your using new cobs, holders, and a driver ditch the mars frame. It’s worthless. Best bet is to grab a large heatsink or buy individual ones and start fresh. Or just grab some aluminum and pick up a Heatsink on eBay. You can make exactly what your trying reuse but you can do it at whatever size you purchase.
