The MediaLight Mk2 Bulb is no ordinary bulb.  It does not use a cheap COB light source. It contains 32 individual Colorgrade Mk2 chips (more than the 1m MediaLight Mk2 Eclipse, but with identical spectral power distribution) and, unlike COB lightbulbs, it does not require up to 15 minutes to reach target color temperature. This is what we mean by instant warmup.

The MediaLight Bulb is constructed differently from most bulbs and may operate differently with your existing dimmer. It is optimized for Lutron  LED dimmers because they offer a trim adjustment switch that allows for full and accurate control of dimming range. And the good news is that Lutron dimmers are very reasonably priced. In most cases, other dimmers will be just fine, but you may notice the following issues: 
  • Smaller amount of dimming range (Typically 70-90% range vs. 100% with incandescent). It may not go as low or as high. 
  • LED Bulbs may not shut off at lowest dim setting: this is caused by the dimmer thinking the bulb is completely off due to the low amount of wattage an LED consumes.
  • On dimming systems based on X10 or Power Line Carrier (PLC) control technology, LEDs may flicker when modules are communicating due to the small fluctuations in power on the line. 

It is suggested that you test your current dimmers to see if they work with the MediaLight Bulbs that you have purchased.  Chances are that they will work fine. If not, the problem will be resolved by buying a dimmer listed below:

Lutron MS-OPS2
Lutron MACL-153M
Lutron PD-6WCL
Lutron S-600P-WH
Lutron CTCL-153P-WH

Levition N0.6681
Lutron MACL-153MH-WH
Levition N0.6633
Lutron DVW-603PGH-WH-C
Also any of the Lutron Caseta dimmers.  As long as there is a low-end trim, it will work without instability or sudden drop-off on the lower settings.

A19 Bulb a Good Solution for videophiles and Non Videophiles

Excellent product for use in multimedia types of rooms where there may be a need to throw a light on while watching TV, including two-piece projection systems. Images don't wash out from the loss of contrast and overall image quality is maintained.

Peace of mind.

This bulb is so good to have for times when you need more ambient light, but don’t want to risk biasing your grade. I use it specifically when I’m not doing difficult or important grading.

Best bias lighting products you can buy and the customer service is great. I chatted with someone from MediaLight before making my purchase and they helped me pick the correct items for what I was wanting to achieve. I will be be a customer for life and won't hesitate to recommended MediaLight products.
