I just posted the second  in a series of articles on LEDs on the subject of color rendering in LEDs and how it can be improved.

I just posted the first in a series of articles on LEDs in celebration of our first LED product coming soon.

I posted the last and final part of the Metal Halide Fresnel series in the Articles section of the blog.  In Part IV, I discuss the Cool Lights Bulb choices for our coming Hardlight series.

I just posted the part III of the Build Your Own Metal Halide (Low Cost HMI) Fresnel in the articles section of the blog. In this part, I talk about what we’ve been up to behind the scenes to leverage all this information to create what we call the Hard Light Series which will be the perfect complement to our already existing and soon to expand Soft Light Series. Part IV will be posted shortly where I talk about the standard Osram bulb choices in the Hard Light series and the equivalent replacements that can be had for lower cost.

I just posted the long awaited and eagerly-anticipated part II of the Build Your Own Metal Halide (Low Cost HMI) Fresnel in the articles section of the blog. I also posted a new article on Electrical Safety Guidelines.

I just published Part 1 of a multi-part article on building your own low-cost HMI type fresnel in the Articles section of the Blog.  In part 1 we cover a bit of the theory behind HMI, what it is and how we can find “generic”, less expensive versions of it to serve in our low cost fresnel.

Build Your Own Metal Halide (Low Cost “HMI”) Fresnel – Part I

I just put up the test results for our bulbs. I’ve had them for a long time and had been meaning to put it up but finally got around to it. We also included a test report of an Osram Dulux L 3200K bulb for comparison purposes. You can find the test results here.

I just posted two new articles relevant to fluorescent lighting for media production in my blog. They are:

“Color Temperature and Color Rendering Index”

and

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

You can post comments if you have some relevant information or corrections to make!
