requires <strong>uniform vertical illuminance at eye level<\/strong>.<\/p>\n<p>GU10 bulbs are:<\/p>\n<ul>\n<li>point light sources<\/p>\n<\/li>\n<li>\n<p>limited in luminous flux<\/p>\n<\/li>\n<li>\n<p>narrow in beam distribution<\/p>\n<\/li>\n<\/ul>\n<p>This makes it difficult to deliver consistent biological signals across a space.<\/p>\n<p>Large-area wellness lighting
