Thinking back not long ago LED video lights were outside the normal budget. Bigger and better designs plus affordable prices make LED video lights the new standard. I don't know anyone using anything else these days for portable on-camera lighting. These 312 Portable LED Video lights aren't very new. People have sent in links to this LED light but it wasn't something I was very interested in. There is however one version of this that's fairly new, which recently caught my attention again. So check carefully and don't get confused between them if you're shopping for one.
Relative Size on Camera
The first version of this LED video light comes in with 312 LEDs with Variable 'Color Temp'. If you've seen how this technology works, you'll basically be ending up with about 1/2 the light output. Here's an old article I posted about the larger color changing LEDs https://cheesycam.com/latest-led-color-changing-video-light/
Although color changing features make for a great LED light, you'd be carrying around a fairly large form factor for just 1/2 the power. Not something I was interested in for this type of portable on camera video light. The latest version of this LED light is much more interesting. It seems as if they've removed the color changing feature and just added 312 bright 5400K LEDs.

Why is this more appealing to me now? Well for people like me looking to stack portable LED video lights like the Z96, this might be the better and cheaper route. If you purchased (3) Z96 LED lights at current price, you'd end up paying more, come in with less LEDs, and have to deal with more batteries and more pieces. The 312 LED video light is a good size to still be considered portable with very little pieces to muck around with. There are two versions of the 312 LED video light, but all come with 2 Batteries, Battery Charger, a diffusing panel, and hot shoe adapter. Not only a better deal on the total number of LED's compared to the Z96, but throw in the rechargeable batteries (looks like Sony) + charger, the price is looking pretty sweet. It's a very clean professional looking form factor with obvious dimmer knob(s) on the back and a nice battery meter to show you how much power you have left.
