CoolStar 150W CFL Features

The CoolStar 150w CFL is balanced to 5600˚K which means it's the perfect bulb to mix with daylight. It is perfect for indoor video or photography shoots where a window is present because all your light will be a neutral white. Compared to a 3200K halogen, which would make your subject appear very orange.

Our CoolStar 150w CFL emits considerably less heat then a traditional halogen bulb. In the images above we left three CoolStars 150w lamps on in a Large SilverDome for 15 minutes and then left a traditional 1000w halogen bulb on for five minutes in a Large SilverDome with a thermometer hanging in the inside of the soft box. In [figure 2] you can see that three CoolStars left on for 15 minutes raised the temperature to about 78˚. In [figure 3] you can see that the single 1000w halogen bulb left on for only five minutes raised the temperature to 100˚+. The CoolStar is equivalent to a 450w - 500w tungsten light. Meaning there was more power going to the CoolStar portion of the experiment yet it still maintained a temperature way below the halogen bulb that was running for only one third of the time.

The CoolStar 150w is the perfect bulb to mix with sunlight. In the above experiment we demonstrate this outside on a sunny day. The first image [figure 4.1] is a straight sunlight image, notice the high contrast, deep shadows, and loss of detail in the shadow areas. In the second image [figure 4.2] we used a halogen fill light, notice the orange color shift that results from a lower color temperature of 3200K. This image does produce a better looking photograph with less contrast and more detail in the shadows though. In the third image [figure 4.3] we shot with the CoolStar 150w CFL bulb, notice there is no color shift, but the shadows are filled in nicely and maintain detail throughout. Without the use of the CoolStar in a situation like this you would be stuck with an untrue rendition of the color in the subject you are photographing.

Every CoolStar 150w bulb comes in a Photoflex Transpac CruzTube rigid carry case. It weighs in at 3 lbs. and features soft material on the inside of the case as well as a removable top liner in the case.
