Lighting - Lighting Comparison Part 2 - Halogens

Here is a comparison of two types of 12 watt halogen bulbs individually and combined with the Excella T12 fluorescent lights I looked at in the last comparison.  There are a lot of graphics on this page, so it may take a few moments to load. I did this comparison in late 2003. The information here was valid at that time.

Please read the introduction in Part 1 before continuing on on this page.  All the same information, test setup, and disclaimers apply.

The color of the boxcar is (as best as I can tell) boxcar red.  The color of the switcher is a very flat weathered gray/black with some brown on the trucks.  The board behind the diorama is white poster board. The fascia on the front of the fascia is flat black.  The ballast is normal mixed-gray Woodland Scenics ballast as supplied with the kit.

Bulbs

For this comparison, I compared two different types of Halogen Bulbs.  The first is a standard MR16 like you would find at your local Home Depot or similar store.  The second is a Solux "full spectrum" bulb that I orded from 1000 bulbs.com

 

Comparison Table

This is a large table (it has to be so you can see enough detail on the individual photos for comparison.), so it may take a few minutes to load.

To fit better on this page, this table is rotated 90 degrees as compared with the original light comparison table used in Part 1

Conclusion

The Normal GE MR16s have a higher light output than the Solux bulb.  The GE bulb, however, has a very noticeable yellow/red tint.

The Solux bulb has excellent color rendering, but lower light output (and at least the same heat output)

The combination of the Solux and the Excella produce good color rendering.  The solux is able to provide fill light and some "sun" shadow.  However, with the 36 degree spread, the shadows are far too soft.  If you purchase the Solux bulbs, I would recommend going with a tighter beam spread, such as 17 degrees.
