It's The Internet - everyone thinks they're an expert.

I no longer read the Flickr Strobist group because of all of the misinformation. David Hobby's site, however, is still worth an occasional visit.

So my old WL10,000 lights use capacitor switching, right?

If so, they should tend to have minimal shift in color temperature and tint over the three power levels, right?

Paul, years ago some of the small speed light makers (Vivitar 283/285?) had some yellowish filter over their speed lights. I don't see that with any of the new ones so I guess they think the digital cameras will compensate for the WB automatically.

However, I suspect they are missing out the fact that using them with daylight causes a blue tint against the warmer sunlight. My Nikon SB-900 measured out to be around 6,500K which seems really blue and cold in use, besides well outside what Nikon's default flash WB is too.

Nikon seems to call Daylight 5,200K in their settings. If the Einstein is 5,650K, would adding something for a 20+ Mired shift (Lee #444 Eighth C.T. Straw) help if one keeps the Nikon set to Daylight for outdoor flash fill and not Flash which might be 5,600K?

The 5600K is the color from the tube. The dome drops the color temperature by about 300K. We offer a UV coated dome that will drop color temperature by another 300K (600K total) from 5600K.

Also, good white fabric will drop color by 150-200K, while bad white fabric (where brighteners are used) will vary wildly, and can go very very blue.
