36 Lighting & Controls: Transitioning to the Future NO MAN’S LAND Going lamp-for-lamp with 28W or 25W F32T8s can save energy, but often after they are installed there is not a sufficient amount of potential savings to go with an optimal solution, such as with delamping with high lumen 32W F32T8s and high performance ballast. ” DELAMPING & Lamp-for-lamp COMPARISONS Following are just a few examples. 2x4 Lensed Troffer with 2 F34T12s or Basic Grade F32T8s These troffers can be retrofitted lamp-for-lamp or delamped.

Most LED hibay and exterior fixtures have only about 70 CRI. Where CRI is really important, such as with big box stores and car dealerships, 90+ CRI CMH can make colors and textures look better, which can make the merchandise more sellable. COMPARISON TABLE Architectural grade exterior fixtures, typically cast metal, are expensive no matter the light source. If the fixtures, reflectors, and lenses are in good shape, it is often much more cost effective to retrofit them with electronically ballasted CMH than to replace them with new, similar-grade LED fixtures.

The reflector is necessary to get power to both sides of the fixture. The BF depends on how much light is needed. 8’ Strip with two 60W F96T12 CWs Almost every facility manager and maintenance person wants to get rid of 8’ lamps, but some retrofit contractors and others want to retrofit these fixtures lamp-for-lamp with full or reduced wattage 8’ T8s. Delamp vs. Lamp-for-lamp Retrofit 39 A kit is necessary to convert this fixture with 4’ T8s. If the existing up and side light is important, it can be a strip kit.
