Some materials migrate between projects, such as a plastic mesh that found use as a lamp cover, a bracelet and the speaker cover in the Hero.
Then, it was exposed to a 400-W metal halide lamp covered by a blue glass filter (B-440 UV vis bandpass filter, Edmund Optics Inc., Barrington, NJ, USA).
The light source, utilized during the dark-light shifts, was a white lamp covered by a green filter (medium green filter 660, GamColor, Los Angeles, CA) that transmits light mainly in the 500 580 nm wavelength range.
The initial (F0), the variable (Fv) and the maximum fluorescence yields (Fm) were determined upon excitation with green light (75 μE × m-2 × s-1) provided by a projector lamp covered with a red and a blue filter (CS 4 96 and CS 3 69 Corning Filters).
Coconut Lamps Cover Your Walls in Shadow Art.
During phase assessments subjects remained in dim light (4,100°K lamps covered with red filters, <3.8 µW/cm2) and provided saliva samples every 30 minutes.
As a control, plants were exposed for 8 h under the same lamps covered with polyester film (no UV-B treatment, UV-B: 0.04 W m-2, UV-A: 0.4 W m-2).
Canopy leaf irradiation (CLI) plants were screened by polyester (PE) that absorbs UV-B with the first, top two, or top three leaves threaded through the filter to receive UV-B-irradiation from lamps covered with cellulose acetate (CA) to filter radiation < 290 nm.
On a floor lamp, Ms. van Amringe covered the cream shade with black net and wound roses down the stem of the base ($1,800).
