what do you think?

still a great set up.. but worth considering...

It's good for people to have caution when dealing with any kind of eletrical source,and to be honest I took the heat into consideration when I bought the fan!,first thing I should mention the glass tube wouldn't break if the fan was on or off! the glass is tempered! I don't know how hot the glass could get before it cracked if it would at all? I had the system running for over a hour without the fan hooked up and I believe within a hour the bulb would have reached maximum heat! the glass never split or broke! and when the fan is on as you could see I could actually hold the glass tube in my hand and felt warm like the top of your dryer! r........

I could actually touch the 1000w bulb myself with my fingers it was hot but not hot to the point you couldn't touch it with your bare flesh.....I might take a picture later to illustrate me touching the bulb while it's turned on just to show that the fan works so well that the bulb it's self is being cooled down!................

The fan doesn't allow the bulb to heat up enough for any consideration for heat! as soon as the bulb produces heat the cool air is sucked into the tube and pass'es over the bulb so quickly that any heat generated is being wisked away with the air coming into the glass tube that is drawn by the fan........Like I said earlier I was shocked! that it worked so well and I'm the type of guy that gets paranoide when dealing with heat and electric sources lol..................but this set up really has my mind at ease.......

The manafacture of this fan recommends not to use the fan in a air duct that exceeds 155 degree's the bigger fans can handle 180 degree's........I guess what one can do is take a tempature gauge and put it close to the 1000w bulb and see what it reads? maybe it won't reach 155?.............of course with the fan sucking the heat very quickly the heat is reduced to almost a tropicial breeze! or less.........and I am sure this fan being used inside of a full hot roaring furnace probably producing more heat then a 1000w hps bulb?..

Come to think of it I remember a couple of times I would be down in the sub basement of my old house working around the furnace and actually touching the duct work that runs of from the furnace and that being almost untouchably hot!.......and the duct work on the cool tube is no where near hot! not even close!..........................

I am a very paranoide guy when it comes to heat sources and always fear a fire in waiting lol....but this set up makes me feel completely comfortable.....but just for arguement sake and my own peace of mind I will pick up a tempature gauge and leave it in the exaust of the out take duct and see what temps I get!.....................................Could possibly someone from this forum put a tempature gauge close to their 1000w bulb and tell me what reading they are getting?.............Like I said though I feel the fan is working great and my tempatures are no where near 90degree's.....

All and all safety is the key issue when it comes down to anything! and I recommend anyone who attempts such projects takes all safety into consideration..........
