SAFETY Warning: Don’t Bake All Bulbs Oven lights are handy. Just flip the


switch; no need to open the oven and release heat to get a baking update. But be careful when replacing this little light. Never put a bulb in the oven that’s not built for high heat. Compact fluorescent lamps (CFLs) use


less energy than classic incandescent bulbs, but they’re not safe in extreme tempera- tures. Most lighting labels designate safe temperatures, but warnings may be in fine print. Need to replace your oven light? Look for appliance light bulbs. Found at Home Depot, Lowe’s, and other retail- ers, these bulbs are designed for extreme temperatures in ovens and refrigerators. The hardy bulbs are here to stay; 40-watt appliance bulbs are exempt from federal lighting efficiency standards. Why won’t CFLs work? Instead of heating a filament until white-hot to


produce light like an incandescent bulb, a fluorescent lamp contains a gas that pro- duces (UV) ultraviolet light when excited by electricity. The UV light and the white coating inside the bulb result in visible light. Since CFLs don’t use heat to create light, they are 75 percent more energy ef- ficient. But the technology that cuts energy use doesn’t stand a chance in an oven’s 400+ degree heat. CFLs are good for the pocketbook but


not perfect in every situation. Keep these tips in mind: 1. Don’t dim unless it’s dimmable.


Buy a specifically designed CFL for a dim- mer switch application. 2. Don’t flip too fast. CFLs work best


if they are left on for more than 15 minutes each time they are turned on. Older bulbs take 30 seconds to three minutes to reach efficient operation. Frequently switching


RECIPE Upside-Down Shepherd’s Pie


1 pkgs. (20-oz.) refrigerated mashed potatoes 1 lb. (90%) lean ground beef 1 Tbsp. margarine, substitute butter 1 cup (half a 10-oz. bag) chopped onions 1/3 cup ketchup 1 tsp. dried dill weed


1/2 cup loosely packed fresh parsley leaves, chopped 1/3 cup reduced-fat sour cream Dill sprigs, for garnish


Preheat oven to 450 degrees. Spray 1 1/2-quart ceramic or glass baking dish or deep-dish pie plate with nonstick cooking spray. Press cold mashed potatoes onto bottom and up side of casserole. Bake potato crust 20 minutes or until edge is golden.


Meanwhile, heat 10-inch skillet over medium-high heat until hot. Add ground beef and cook 4 to 5 minutes or until beef is no longer pink, breaking it up with side of spoon. Spoon beef into paper-towel-lined bowl to drain. In same skillet, melt margarine over medium heat. Add onions and cook 6 to 7 minutes or until tender and golden, stirring occasionally. Return beef to skillet with onions. Stir in ketchup and dried dill. Reduce heat to low; stir in parsley and sour cream.


Spoon ground-beef mixture into mashed-potato crust; garnish with dill sprigs to serve.

them on and off shortens bulb life. Newer CFLs feature an ‘Instant on’ capability; look for that on the lighting label if you expect frequent flipping. 3. Give them air. CFLs may be used


in enclosed fixtures as long as the enclosed fixture is not recessed. Totally enclosed recessed fixtures create temperatures too high for CFLs. 4. Protect CFLs outside. Look at the


package or bulb for temperature restric- tions before using a CFL outdoors. 5. Don’t shake. Don’t use CFLs in


vibrating environments such as a ceiling fan or garage door opener. 6. Do the twist. Always screw and


unscrew the lamp by its base. Never force- fully twist the CFL into a light socket by the glass tubes.
