Finally got to play around real quick with some comparisons between the almighty Sundrop and my standard mule. We already know about the Sundrop's led, and for reference, the regular mule has an SOB driven Q4 cree from the Shoppe.

First off lets look at the differences in the tail design:

As you can see, the Sundrop features a bit more metal around the hindquarters than the standard clickie mule. Feels more finished, and hides the screws a bit more. I'm liking it.

Rear view of the head:

With Don's 3.6v reminder, since he was kind enough to put one together for me that could handle my rechargeables since that's all I use. Many thanks again Don!

Next let's introduce my test model, Chomsky:

(From here on out, each set of shots was taken with identical exposures, and the white balance set to sunlight. Only resized, no color or density corrections. Shot with my Canon G9).

And with the Sundrop:

Due to his stylish RGB attire I figured he'd work out fine as a makeshift CRI test dummy. Better yet he also provides both a white reference as well as a vague skin tone ref.

Here's a little scene I put together with him and some various colored items. Of note would be the makeshift mini color chart, taken off of the screen printed package of a snack I had consumed earlier:

Something more natural you say? Ok lets try out this geode I had laying around.

First off going head to head against each other in the same shot:

Next we'll look at the fun side:

Observations:

The Sundrop provides fantastic color rendering compared to the cree based light tested here. I shot a few pictures with other lights, but they all pretty much looked similar to the regular mule, with the exception of a hotspot since they had reflectors.

The colors of the agate inside the geode really popped and held true with the light of the Sundrop.

It's just a beautiful color of light, and while it does look a bit like tungsten light, when I changed the while balance to tungsten it was very blue. So this is a great shade of light.

When I stop by my old job this week I'll try to remember to bring the Sundrop and I'll attempt a test of the color temperature using a minolta colormeter. Hopefully it will give me an accurate reading in kelvin.

In the end, both lights are awesome, and each go about illuminating things just fine. But from here on out, for macro photos, or any led-lit pictures I take, it will be the Sundrop that leads the way.

Hope you enjoyed this, thanks for looking.

To be continued. I've got to find some human test dummies to try this wonderful light on.

Thanks for the pix, Stillphoto, and a most interesting test. I'm not sure that it tells us much, however, because you conducted it using your camera's preset "sunlight" white balance, and these presets are notoriously variable from camera to camera. So it's hard to say how much of the difference I'm seeing in color balance is the result of differences between the Sundrop and Mule, and how much can be attributed to the way the preset "sunlight" white balance is reacting to these two different lights. A better, more revealing test might be to set white balance manually for each light... easily done with the feature set of your G9... and then compare the results side-by-side.

I agree, it was just a simple side by side with a single white balance to show how far both were from a fixed color temperature. For the most part, everyone's sunlight white balance is withinin 500 kelvin of each others, somewhere between 5200 and 5500 k.

Now, considering I have raw files of each photo, I can go back and white balance for each of the "scene" shots since I have the same white reference in both. I'll try to post those later.

Thanks for your input.
 
Cool Stillphoto! :thumbsup:

Now I am confused here with the discussion of white balance. Having a pair of shots made with the same balance seems the best means of comparing the shots? If we agree that the sun should be our standard and not incan then isn't sunlight balance the one we would want? If each image is manually tweaked to get the white to look white then aren't we filtering or balancing away from a fair comparison?

Is the assumption that our eye will adjust to see the white as white so a manually balanced image will show what our eye will see once acclimated? It would be interesting to see what shifts in colors comes about from adjusting the white balance.

The shot I would like to see is the same scene, using sunlight white balance, and using sunlight for illumination.

On my computer, what appears to be a Loc-Line segment looks to be red under the Cree and orange under the SunDrop. Which color better describes this item?
 
The loc-line segment is bright orange, correctly rendered with the SD. I held it up to my screen, and monitor calirbrations aside, it was a near match.
 
Stillphoto, thanks for taking your time with this thoughfully well-put comparison.
 
There is definitely a brightness/gamma difference between the two, with the Sundrop being brighter.

Sundrop images are definitely warmer rather than neutral, but not overly so. Warm in a very pleasant way.

Really love the look of the Nichia 083. Can't wait to see it in person.
 
Thanks for the comments guys!

Ed, you nailed it there, warmer than neutral for sure, but in a very pleasing way. That gamma increase is correct, I believe that sapphire lens is bending light back on course that runs errant in the mule setup.
