• 5% UVB and 30% UVA full-spectrum output formulated for birds
• UVB supports vitamin D3 synthesis and healthy calcium metabolism — vital for hens laying eggs
• UVA lets birds see colour the way they do in nature — supporting natural behaviour, feeding and preening
• Self-ballasted — screws into standard fixtures or the AvianSun floor lamp stand
• Position within roughly 30–45 cm of the perch, with shade available

Replace yearly: UVB output fades long before the visible light does.
