NAB 2014 Drew with Alzo Video talks about the upcoming additions to their popular High Intensity LED Video Lights. These lights are not using multiple standard plastic lensed diodes common with most flat panels adding additional benefits with this design.
The High Intensity LED can provide a true spot or flood with the optional fresnel lens and can be flagged using barn doors without multi-shadow issues. If you're a photographer who has worked with strobes, you'll notice the strobe-like design make this compatible with hundreds of light modifiers already available from softboxes, grids, snoots, strip boxes, dishes, and more.
If you've been experimenting with Flash photography, you might start to gain interest in light modifiers. With different types of modifiers you can shape the light and target exactly where you want it to be. I know some guys who carry between 4-8 speedlite flashes (or more) when on assignment. My favorite modifiers for small speedlites are honeycomb grids or snoots. These create a somewhat spotlight effect perfect for hair, rim lighting, or background seperation.
If you're running around at an event, the most common modifier is the large diffuser. So that you aren't casting harsh shadows, you'll need a Stofen, Light Sphere, or Globe. Here's a great kit for a great price and even comes with a set of colored diffusing panels. We often use colored Gels over speedlites, but these colored diffusers seem to work in the same way allowing you to add different colors to the background without having to change out the whole roll. The video seems outdated with the $100 dollar price tag, as they can be found much cheaper now.
