CLEARANCE: Gavita Pro W 150 DE Replacement shade

Sometimes you need a little less light, but you want to keep using high efficiency 750 W or 1000 W fixtures. Sometimes in very large rooms your height is limited. In that case, a wide reflector, such as the W 150 DE, a double-ended reflector with a 150-degree beam angle, solves your problems.

A wide reflector is not suitable for a smaller room, because it causes more losses on your walls, reducing the average light levels and the efficiency of your light installation. Here are the typical applications for a wide reflector:

• In a large (vegetative) room where you use lower light levels, you want to spread the light of your fixture in a uniform way over a larger surface. The wide reflector allows you to do so.
• When you combine HPS with plasma light in a vegetative room, you replace part of the HPS light with plasma light. Depending on the ratio of plasma/HPS fixtures you will need to spread your HPS light over a larger surface. A wide reflector allows you to still use a high-power fixture, reducing the initial investment, installation costs and re-lamping costs while getting a perfect uniform lighting.
• In a large flowering room with limited height, the wide reflector allows you to come closer to the crop.

It’s not easy to define what the standard spread of the reflector is, as it is used at various intensities.
In a large room in general though the configuration is very similar to a HR96 when you need the same light levels. The added advantage of the wide reflector is a better uniformity maintenance over distance, while getting a bit closer to the crop, through a much wider overlap.

You can achieve the same light intensities and the almost the same uniformity with the HR96, but at a bit more distance to the crop, so you need more height for that. When you need lower intensities, for example when combining with the plasma light in a vegetative room, the wide reflector is in most cases the best choice for DE lamps.
