So I'm using an old Lithonia HPS 70 watt lamp and was wondering what would happen if i put a 150 watt bulb in it.? Any ideas?

It might work if the sockets are the same and if it fires the bulb but it will only burn at 70w so it will have a different spectrum then intended.

This will require a new lamp?

You come to the wrong place with that HPS talk.. 
j/k 70 w hps only takes 70w hps.
Get an LED!

So LED is the best..? For vegetative and budding/flowering stage with highest yield?

Guess im starting off but not much of a budget, this is my new hobby so ill throw money at it. No venting, in a wide open room above a garage far from other houses.

Good luck bro, what are the dimensions of the room you are growing in so we can get a sense of how much area you need to cover, also is your room ventilated and insulated?

The actual grow area is 4 feet by 4 feet. This does not include the sprouting/germ area.

You got a way to exhaust heat or air condition?

"make an offer" I have received many good deals this way through them on make an offer items.
You could easily offer 25% less and I'm sure they would be close if they didn't accept it. Would rock the house for you.

At your scale. Yes. LEDs are best. That doesen't mean they don't have any disadvantages over HPS or other light sources.
HPS and Sunlight are cheaper. HPS over time is more expensive however.. I assume you prob need 600w in a 4x4 for solid ppfd#'s versus 8x cxb 3590 @1400ma.
About $200 for HPS light and reflector. $40 for fan exhaust for that air cooled hood, connecotrs, etc. .. +650 watts of juice or so.
ABout $450 for those crees if you handbuild. Approx 450 w. -> no blower, no reflector, no bulbs to change, no glass to clean, considerably more amount of light gets to your plants via LEDs- and its better imo because you can get closer. Leds run so cool they will bleach plants before they burn. @.23kw cents/hr that 200 watts translates to about $$8-12/month on elec savings.
Other savings:
How often do you change your HPS bulb? etc. etc. LEDs and Ballasts should last at least 8 years. HPS? Varies dramatically.
Check out cobkits website. Hes got great stuff.
If I were you: run your hps into the ground or sell it and save up for led.
GL HF!
