Build Your Own Metal Halide (Low Cost “HMI”) Fresnel - Part IV

Sunday, July 15th, 2007

I got into this “Cool Lights” business of mine because I thought prices were outrageous on pro level fluorescent fixtures. You can see all over this site the manifestation of what I decided to do about it; starting with the Cool Lights video and ending with low cost fluorescent fixtures. Well, I’ve gotten the same feeling again on another lighting technology: HMI. I was searching for an energy efficient hard or point light source to complement our fluorescent Cool Lights Softlight Series product line and was learning about HMI as the natural solution. Crazy prices though and no good reason at this point to have them so high.

In the last part of this article series, we’ll take a look at the Cool Lights bulb choices for the various fixtures using Osram as the standard and then coming back and looking at other equivalents. You’ll see we chose to work with industry standards so you won’t be locked into using Cool Lights bulbs for sure. (more…)

Build Your Own Metal Halide (Low Cost “HMI”) Fresnel - Part III

Sunday, June 24th, 2007

I got into this “Cool Lights” business of mine because I thought prices were outrageous on pro level fluorescent fixtures. You can see all over this site the manifestation of what I decided to do about it; starting with the Cool Lights video and ending with low cost fluorescent fixtures.

I was searching for an energy efficient hard or point light source to complement our fluorescent Cool Lights Softlight Series product line and was learning about HMI as the natural solution. Crazy prices though and no good reason at this point to have them so high.

In the previous two articles in this series we talked about building your own metal halide fresnel for under $500 as my own way of educating the world on what’s going on with HMI’s, the ridiculous reasons they have been artificially overpriced and also as the introduction for my own Cool Lights Hardlight Series. I’m afraid it will take some serious re-education (and perhaps even de-programming) for some people to accept that it’s possible to offer “HMI” for the prices I will be. In this, the next-to-last installment of this multipart article I will talk about our progress on the metal halide Hardlights. In Part IV, we’ll talk about the bulbs we chose and their equivalents on the market… (more…)

Electrical Safety Guidelines

Saturday, April 21st, 2007

The following are the same guidelines found in the Electrical Safety section of the Cool Lights Video. Please read this before completing any electrical projects! We take the operation of electrical devices for granted as an unconscious thing nowadays. You can’t afford to do that once you start building electrical devices… (more…)

“Green Spike” or Why Do Fluorescent Lamps Have Mercury in Them?

Thursday, January 11th, 2007

With all the talk about the green spike in the spectral energy distribution of fluorescent lamps and how that can affect us as media creators, I thought it relevant to include an excert from a publication by the National Electrical Manufacturer’s Association (NEMA) entitled “Fluorescent Lamps and the Environment”. This publication and a lot more valuable information can be found at the NEMA website devoted to proper lamp disposal called www.lamprecycle.org. (more…)

Color Temperature and Color Rendering Index

Thursday, January 11th, 2007

Introduction

We hear a lot about Color Temperature (CT) and CRI or Color Rendering Index in film and video production. You may have even heard of “Correlated Color Temperature” or CCT (and what is that all about?). Some are concerned about their ability to have colors rendered accurately and consistently each time they record an image of a product or person. They are also concerned with the color of the light they are using. These two concepts should not be confused but they often are. In the beginning I confused them just like many. In the past few months however, as I was searching for suitable bulbs to sell with my Cool Lights fixtures, I got a major education in more aspects of fluorescent tubes than I ever thought I would want or need! I never planned to have a “Cool Lights” brand bulb but the realities of what is commonly available in Asia drove this decision. I had to find an established manufacturer willing to produce a higher quality bulb, but still economically, or I would not be able to offer the bulb I wanted at the cost I wanted to. Before we go further, let’s define CT, CCT and CRI so we have a common basis of understanding. (more…)
