My photography page mentions planned upgrades for my tabletop set. The first planned upgrade was to improve the lighting. I had decided on continuous tungsten lighting rather than fluorescent bulbs or strobe lights as I wanted a bright, easy to visualize set-up.
There are several options for continuous tungsten lighting including the Tota-light or Pro-light from Lowel, the fresnel studio lights from Arri and the much cheaper Chinese knock-offs widely available on ebay.
I first found about the low voltage Dedolight while watching a video comparing (in order of ascending price and performance) the 200-watt Lowel Pro-light, the 150-watt Arri Junior and the 150-watt Dedolight. The Dedolight was clearly superior but at a substantially greater price than the two competitors. I continued to look at lights from Lowel and Arri, and the Chinese knock-offs.
After a month of indecision, I stumbled on a used Dedolight (including accessories) in “as-new” condition on ebay with a buy-it-now price including accessories that was $200 less that new. The ebay Dedolight arrived at my apartment about four days later.
It’s a great light and I believe it has improved my artificial light photography. With brighter lighting I am able to use higher shutter speeds. Since I shoot almost exclusively handheld this is a big advantage.
The Dedolight plugs into 120 volts but an on-board transformer steps it down to 24 volts allowing the light to use a robust and relatively inexpensive bulb. Other features include a smooth nearly 20:1 zoom and a built-in dimmer. I have it mounted on heavy duty light stand with a small, lightweight diffuser attached using a flexible clamp.
