The solution to your UV needs in a compact fluorescent! But the Compact Max Pack is even more! The Compact Max pack comes with a compact UV fluorescent and a reflector shield! This reflector concentrates and directs the UV down thus doubling the output of UV given off by the compact! These units screw into an ES fitting so cutting down the size requirement that a normal UV tube needs. The UVA and UVB output of these globes is beneficial by increasing appetite and activity, aids in the treatment and prevention of metabolic bone disorder and increases overall general health.
