Accurate Bulbs for Still Life
I need to know what lumens to paint by and to illuminate the still life. 5000K? I'm only familiar with Verilux lights.
For installations where color-critical illumination is important, such as artwork creation, we recommend the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000). This product povides full-spectrum output and is D50 calibrated, which is a specification for a light source that approximates warm daylight.
I'm trying to reproduce ''north light'' not warm daylight. Would this bulb do that? You also sell product #4005C.50 and #4005C.30. Any difference?
For lighting that mimics northern light, we generally recommend the 6500K option, as it provides a cooler blue light output than the slightly warmer 5000K color point. In the hopes that it proves to be helpful, we have attached a guide comparing the 5000K and 6500K options for artwork creation purposes.
Difference Between 5000K and 6500K Bulbs
Regarding the 4005C.50 and 4005C.30, these items are solely differentiated by the color temperature that they output. The 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb (PN 4005C.50) will provide a much cooler color temperature than the 3000K CENTRIC HOME™ Flicker-Free A19 10W LED Bulb (PN 4005C.30). Otherwise, the two items will provide the same amount of full-spectrum light.
