Phillips LED Bulbs w/ Lightbulb Adapter & 5th Gen Lightsphere

Wondering about several details when using Phillips LED Bulbs with Gary's Lightbulb Adapter & the new Gen 5 Lightsphere: 


1.) LED bulbs typically get larger as the wattage goes up... Do you have any experience with bulbs larger than the 11W Phillips that Gary talks about? Is it safe? Will larger than 11W bulbs fit in both the Lightbulb Adapter & Gen 5 Lightsphere?

2.) Are there any "melting" or discoloration issues with either the Lightbulb Adapter or Lightsphere when used nonstop for hours at a time with LED bulbs?

3.) Can you use the dome on the Lightsphere when using LED bulbs? Will it create heat issues, melt, soften, or discolor the dome?

4.) Does GF have any data on color reproduction for any other bulb wattages/mfgr's?

Sorry about all the questions... I purchased two sets of Lightbulb Adapters with the new Gen 5 Lightsphere this morning. Looking forward to using them, but have a few questions & concerns before I purchase bulbs.  ;-)

Mike

Hi Mike,

We've used 11w and 12w options mostly because they were more easily accessible and due to the aforementioned sized limitation. That said, larger bulbs can work in the unit. We have tested incandescent bulbs of 100w+ for extended duration, and not had any problems with heat melting the modifier. The much cooler operating LED bulbs have never once been an overheating concern, as we've left those on for hours and hours while demonstrating at trade shows.
While use of the PowerGrid is pretty common (and not problematic), we do not recommend using the White Dome as that prevents any air circulation within the modifier and could lead to overheating after extended use.
We do not have any other published data on bulb options but would encourage you to seek LED bulbs with a CRI of 85 or higher. Along with Philips, we've been pleased with the quality from Feit bulbs.
