The invention relates to highly concentrated agents for the preparation of sunscreen final formulations, comprising 15 to 50 wt. The pharmaceutical formulation contains peroxidic species or reaction products resulting from oxidation of an alkene, such as geraniol, by an oxygen-containing oxidizing agent, such as ozone; a penetrating solvent, such as dimethyl sulfoxide; a dye containing a chelated metal, such as hematoporphyrin; and an aromatic redox compound, such as benzoquinone. The control panel assembly includes a circuit board, a cover and a member. In addition, melting point depressants can be present in the braze alloy in a commercially common quantity or with a considerably increased proportion.
