Reflector Style LED Lights for Gradual Replacement of Ceiling Reflector Light Bulbs Reduce Costs for Businesses and Homeowners

by Barbara 10. March 2014 09:58

Question about the Dimmable BR30 16 Watt LED Short Neck Light Bulbs to replace reflector type ceiling bulbs.

Question: "These light bulbs look a lot like the incandescent lights in our family room ceiling. Changing them is a real pain: requires a very tall ladder. We do like to dim the lights when we watching TV. Is it possible to mix these? The cost is a lot more. We don't like fluorescent bulbs: takes too long to come on and cannot be dimmed. How long should these bulbs last? What could our power savings be?" Thanks. Devin.

Answer: These dimmable LED short neck bulbs resemble the reflector type spot light bulbs. The warm white glow is similar to an incandescent bulb. Each bulb gives essentially the maximum light of a 100 watt bulb when not dimmed yet uses only 16 watts of power. Figure on about 3 years or 50,000 hours of use per bulb. The light is instant on, not like a CFL type bulb. BR30 light bulbs have an expanded reflector: the results are  narrow soft-edged rays and fewer shadows. Use these LED light bulbs for spot lights, flood lights and indoor lighting. 180 degree beam. This is a UL listed light bulb.

LEDs, or light–emitting diodes, are semiconductor devices that produce visible light when an electrical current is passed through them. LEDs are a type of Solid State Lighting (SSL), as are organic light–emitting diodes (OLEDs) and light–emitting polymers (LEPs).

Incandescent bulbs are inexpensive except for the 65 to 100 watts of energy used. (And 100 watt bulbs are hard to find these days.)Here in Iowa the cost per KWH (killawatt hour) is about 7.2 cents, the 12th less expensive in the USA. In the north east the cost can be as high as 18 cents per KWH. The price of LED lights is going down. My son recently began replacing burnt out reflector type bulbs in his ceilings with LED's to lower his power costs over time and to avoid dealing with ladders in rooms with vaulted ceilings. He figured this was less expensive than installing motion sensors to turn off lights in rooms where there was no movement. (His children support the Linn County REC by forgetting to turn off lights when they leave rooms).

We also sell replacement bulbs that look just like incandescent lights in the shape. These LED bulbs use only 8 watts but give the light of a 40-60 watt incandescent bulb. LED Bulb A19 8W, 40-60 Watt Equiv., Warm White, Short Neck. Again figure on 50,000 hours or 3 years continuous use.

Another option to the reflector lights is the COB PAR30 Dimmable LED Bulb, Warm White, 16 W, Short Neck. This has a narrow beam of 60 degrees. Also an Energy Star bulb. COB stands for "Chip on Board." Again UL Listed and Dimmable.

We hope this helps with your decision!

by Barbara 16. June 2009 08:45

Question about the product Product Code: =TD-MXS-40225, the Maxsa Innovations Motion-Activated 80 LED Security Floodlight.

Q: "Are the led lights changeable on this Maxsa Innovations Motion-Activated 80 LED Security Floodlight? What number of lumens does this light give?" Neel

Answer: No, the 80 LED's are not changeable. However, they are rated for 30,000 to 40,000 hours of on time. The lumens are about that of a 40 watt halogen lamp.

Recently, a residential treatment center in New York state chose to equip their center with these lights as a cost-saving, security measure. For this security light, you need a ladder and not an electrician to install the lights. And with solar power you save on electricity, too. The 15 foot cable to the solar panel even lets you install the light inside a building if you choose. Included is a 6V 4ah sealed lead acid rechargeable battery. This light can detect motion up to 35 feet away within a 180 degree detection area. Time, motion sensitivity and LUX (daylight sensitivity) adjustments. And the light can activate up to 360 times on one charge when on for a minute at a time.

Thanks for your question.
Sincerely, Barbara

UV Air Purifiers Help Reduce Risks of Swine Flu, Colds & Virus

by Barbara 1. May 2009 07:32

Question about portable air purifier units such as the Air Pura UV600 for waiting rooms, waiting areas in restaurants, etc. that can help reduce exposure to viruses and bacteria.

Q: "For those of us who work in offices, medical clinics, etc, exposure to viruses, colds, etc. is part of every day. What air purifier do you recommend to reduce the "air pollution" in waiting areas from coughing and sneezing? I don't want to wear a mask or stay home. Thanks. Dave."

Answer: HEPA air purifiers with UV germicidal lights are the best proactive option for those areas. Do continue to take those actions recommended such as the University of Connecticut website: cough and sneeze into an arm or elbow, not into hands; wash hands often with soap and water, especially after a sneeze or cough; sing the “ABC Song” while washing to make sure hands are thoroughly washed; use alcohol-based hand sanitizers; avoid touching eyes, nose, or mouth; avoid contact with others who are ill; stay home from work or school and avoid contact with others if ill; get plenty of sleep, be physically active, manage stress, drink plenty of fluids, and eat nutritious food.

This air purifier uses true HEPA in their filter cartridges, too. Consider using one in a room with a sick child or adult. Remember that HEPA air filtraiton systems must be run continuously to avoid bacterial growth within the cartrdige.

We recommend the AirPura. Made in Canada. The AirPura Black Air Pura UV600 features the UV light inside the HEPA cartridge. Additional filters are available. Colors: black, cream or white.

We recommend that one or more units be placed in patient waiting areas, employee lounges, restaurant waiting areas or other areas where groups congregate. This is one of the better proactive measures for maintaining good health.

Thanks for your question.

Sincerely, Barbara
