Gifts Tips To Your Lover on Valentine's Day

The Valentine's Day is around the corner,what will you give to you lover?Not so as a warm home?


LED light bulbs have some huge advantages over incandescent and compact fluorescent (CFL) bulbs. But they perform differently, so here’s your guide to understanding LED bulbs so you can enjoy their benefits and play to their strengths.
LED bulb designs are constantly evolving, and they keep getting cheaper and more user-friendly. They’re energy-efficient, durable, and they contain no hazardous materials like mercury. But if you walked through your home today and replaced every single incandescent or fluorescent bulb with an LED, you might be disappointed with some of them. Consider the following factors to make sure you’re getting the most out of your LED light bulb upgrades.

Point The Light Where You Need It
Even when an array of light emitting diodes is packed into a “bulb” shaped casing, they still create a somewhat directional light source. This usually means that an LED light bulb will cast more light from the top end of the bulb than from the sides.

Manufacturers often refer to an LED bulb’s equivalent wattage (compared to an incandescent bulb) based on overall lumen output. Incandescent bulbs usually cast an evenly distributed glow, so a “60-watt replacement” LED bulb may not seem to pull its weight in a shaded table lamp. But in a recessed ceiling fixture, an LED bulb may actually cast even more light than its incandescent counterpart.
Energy Efficiency And Durability
One of the biggest advantages of an LED light bulb is its energy efficiency. Today’s best LED bulbs use roughly one seventh of the electricity consumed by an incandescent bulb, or half the power of a fluorescent. One of our favorites, the C. Crane GeoBulb 3 , is a 7-watt replacement for a 50-watt incandescent bulb or a 13-watt fluorescent.
Despite a relatively expensive initial purchase price, LED bulbs will pay for themselves over time by cutting your power bills. But only when they’re actually turned on – so they are especially well-suited for lights that are constantly in use. For example, a ceiling light that’s on all day long will take advantage of an LED’s efficiency better than an occasionally-used reading light.
LED bulbs last for a long time too – typically up to 50,000 hours (which translates to 12 hours a day, every day, for over a decade). This means fewer burned-out bulbs ending up in landfills, and added convenience too – you’ll rarely have to get your ladder out to change a bulb in a hard-to-reach.
Our Bgocled wish you have a happiness  Valentine's Day.
