The ones I'm using have a tendancy to yellow the pic too much. I tried the white adjustment on the camera, but it kinda washes the colors of the snake as well. Looking for something with a higher blue spectrum or closer to a pure white. Have 150w heat sheild lamps so can take pretty much any bulb. Have a halogen lamp, anyone ever try those? Although they tend to have an orange hue. Any advice would be greatly appreciated.
