Pros and Cons about HPS lamps « on: November 08, 2006, 06:44:11 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: Cody

Post 2: Tim (Cody can't Post this)

Post 3  Billy (it is OK for Cody to post...but Tim can't post on this post since he was the last to post but can post on 4th)

Post 4: Sam (Tim and Cody either can post since the last person was Billy and Billy can't post this)

__________________________________

So post only either  Pro or a Con about HPS lamps....

Only ONE pro or ONE con per post

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

Enjoy!

After the arc tube cracks it makes the inside of the lamp look cool

They are bad for trees and can kill them because trees can see red light and they need day and night cycle to survive but a HPS lights shining on the trees makes trees think "its daytime" somehow

They are very efficient...more efficient than metal halide, fluorescent, or mercury vapor. Second only to LPS.

HPS lamps have poor photoscoptic visibility, causing very dark spots between lights.

High Pressure Sodium has bad color rendering, a dreary "barely lit" effect and the lamps cycle.
