What is a more efficient reflector to use if my lamp is universal, horizontal or vertical?
A. Definitely horizontal. Horizontal reflectors can reflect up to 40 % more light back down to the growing area. The light form a bulb is emitted form the arc tube located in the center of the lamp. If it is burning in the horizontal position, half of this light is being directed at the plants while the other half is being reflected back down form the reflector giving a complete distribution of the light. If the lamp is burning in the vertical position all of the light goes out the sides and had to be reflected back down minimalizing the intensity being directed at the growing area. Back To Top • Q. What is a good application for the parabolic reflector? A. Parabolic reflectors distribute the light very evenly but are extremely inefficient in their use of light. They are excellent for a vegetative crop or for lots of seedlings or cuttings but are not very good for high yielding crops with high intensity demands. Back To Top • Q.
