Light Expert...what Is This?

aLRIGHT i FOUND 2 LAMPS AT THE GOODWILL FOR 3 BUCKS EACH BUT I DONT' IF THEY ANYGOOD FOR GROWING...I ALREADY HAVE A VENTED 400HPS FOR GROW SO THIS WILL JUST BE SECONDARY LIGHTING....MY IS CAMMERA BUSTED SO i'LL DO MY BEST TO DESCRIBE THEM....tHE BULBS ARE SHAPED AND ABOUT THE SIZE OF A PEN AND THEY SAY 300W AND 120V ON THEM WHEN THESE ARE TURNED ON THEY BECOME VERY HOT VERY QUICKLY AND YOU CAN FEEL THE HEAT RADIATING OFF THEM...ALSO THE LAMP ITSEL SAY TO REPLACE BULB WITH TYPE T BULB MAX 300W. I FIGURE IF THIS MAKES MY GROW ROOM TO HOT OR YOU GUYS TELL ME THAT THEY ARNT'T ANY GOOD THEN i'LL ONLY BE OUT 6 BUCKS NO WORRIES. ANYBODY HAVE AN IDEA...DID I STRIKE GOLD OR DID I STRIKE OUT

ummm.. what kind of shape? they sound like mercury vapor lights to me..

o.. nevermind.. those are halogen lamps.. no good.. waaaaayyy too hot

Sounds like a halogen bulb, and that would be useless for growing. I could be wrong but it sure sounds like that’s what you have.

Does it look like this?:

Hot Halogens, at the Good will store~

Alright I Just Got Back From Lowes...and Yes It Is A Halogen....so I Guess Im Out 6 Bucks Ha Ha....i Guess I Could Use Them To Heat My House In The Winter

Just Wondering Why Are Halogen Useless For Growing..is It Because They Are So Hot Or Some Other Reason?
