Pros and Cons about MH lamps « on: November 08, 2006, 06:45:16 PM » Author: TudorWhiz
READ THIS FIRST


Here I am gonna start something fun for you......and educational so you guys can learn.....but here's the rules....

only one positive OR a negative on each post....not both Pos. and Neg., also if the post is a negative please put subject as "Negative" or if its a Positive subject it as Positive....

Also I would like each person to get chance to post something....Please don't post 2 times....instead if you are the last person to post.....wait for one other person to post...then you can post as long as there is no double post of the same person
__________________________________

Example

Post 1: Theresa

Post 2: Lucy (Theresa can't Post this)

Post 3  Polly (it is OK for Theresa to post...but Lucy can't post on this because she was the last to post but can post on 4th)

Post 4: Jamie (Theresa and Lucy either can post since the last person was Polly and Polly can't post this one)

__________________________________

So post only either one Pro or a Con about MH lamps....

UPDATE: another idea I had...you can set the message icon to thumbs up for Positive and thumbs down for negative

Enjoy!

If burned horizontally (for universal lamps), arc tube eventually bulges and lamp can explode and sometimes it will bulge severly and become paper thin and then break.

They blow up at end of life and are messy to work with from all of the broken glass

Certain types can replace HPS without changing or modifying control gear. Mostly applies to Philips CDM\CDOs

Arc in the tube can become unstable and oscillate or swirl and periodically extinguish.

Metal Halide only has 10,000 to 20,000 hours which is not good enough.
