More Details
Pearl-30™ bulbs are compact, extremely long-life light bulbs with the highest energy efficiency available. They are direct replacement for conventional incandescent PAR-30 bulbs at 85% energy savings.
While other brands of LED bulbs use only “cool white” or “warm white” LEDs with incomplete light spectrum, Pearl-30™ bulbs are designed to produce true daylight color via dynamic color mixing, and to last over 50,000 hours, compared to 1,000 hours for incandescent lamps.
A Pearl-30™ bulb runs cool due to its specially designed aluminum housing. Its minimal heat generation will also reduce a major portion of the building’s air conditioning energy costs as well.
Its power converter is 97% efficient vs. 85% of our closest competition. It has no electrolytic capacitors that can dry out and fail with time. Therefore it runs cooler and lasts much longer.
It is brighter than the incandescent PAR-30 bulbs at 85% lower energy consumption and 20X longer life, and it contains no mercury. When used with an extant dimmer switch, it maintains the same light quality under high or low illumination.
Based on its energy savings, labor savings, and long life, the return on investment (ROI) for a Pearl-30™ bulb is over 100% a year for 15 years. This is a fabulous ROI for a simple screw-in replacement operation that anyone can do!

“When it comes to saving money and growing our economy, energy efficiency isn’t just low hanging fruit; it’s fruit [lying] on the ground,” Energy Secretary Steven Chu said in a statement Monday June 29th, 2009.
“The impact is huge — it’s the biggest energy-saving rule ever to come out of the Energy Department”, said Andrew deLaski, executive director of the Appliance Standards Awareness Project. Using the department’s figures, he said, “the savings would total between 500 billion and 1.2 trillion kilowatt hours over 30 years. The high-end estimate is roughly equal to the annual consumption of all the households in the U.S. for a year.”
Kateri Callahan, president of the Alliance to Save Energy, a Washington-based nonprofit, said “The little light bulb: It’s like the Goliath of energy savings.” She said that lighting accounts for about 15 percent of energy use in homes, and up to 20 percent in offices.

FAQ on P-series of LED light bulbs
Q. What are the most salient parameters of a light bulb?
A. People buy a light bulb to get light! Smart people want to get a given amount of light at the least cost. Wise people consider the cost of lighting over time. Thus the key parameters to a light bulb is its light output in lumens, its power consumption in watts and related cost of energy, its life in hours, its total cost of acquisition, installation and eventual replacement, and nowadays, its impact on the environment (due to mercury content of CFL and fluorescent tubes and their ballasts). All those factors are tied together in a spreadsheet available from PearlLED.com. LED-based have been identified as the coming generation of light bulbs due to its highest light output per watt (input) and its very long life. But not all LED-based light bulbs are equal in those key parameters. The math in the spreadsheet helps user select the best light bulb for each application. No, LED bulbs are not the best choice in every application. They certainly are the best choice in applications where they’re turned on for long periods such as 8 hours a day, used hard to reach locations, and off-grid living.
Q. What to look for in an LED light bulb?
A. First figuring out the light output you need, by assessing your current illumination level based on extant light bulbs you use. typically 700-1000 lumens per bulb. Look first for LED bulbs that are rated that minimum lumens, then look for its power factor (>0.9), its light distribution pattern (light cone, glare or the lack of), its color or color temperature and its color rendering index, dimmability, and most importantly, its real life or the guarantee period. Be aware of the fact that false advertising galore due to the more complex nature of an LED light bulb. For example, if the application doesn’t require dimmability, why pay for the associated cost? Or why pay a lot of money for a light bulb that is not covered by a guarantee period of at least 5 years?

Q. I saw LED bulbs advertised as containing hundreds of LEDs yet priced attractively. What’s the catch?
A. You get what you pay for. The hundreds of LEDs in the bulb are rated for relative short life such as 10,000 hours. The more LEDs, the higher chance of failure. One LED failure and the bulb is to be recycled away. Furthermore, in spites of their high LED count, their light output rarely exceeds 200 lumens, which is good for a night light but not for reading or room illumination. A $1 incandescent 60W light bulb typically produces 750 lumens. Proper illumination of a room typically requires more than one 60-watt light bulb, often 2 to 6 of them, depending on room size and the purpose: intimate dining? reading?
Q. What is Power Factor?
A. Power factor (PF) is a parameter quantifying how well an electrical equipment is using AC (alternative current) power made available to you via power lines. An incandescent light bulb for example has a PF of 1. Most personal computers have a PF around 0.65, because the current flowing into them is no longer the ideal sinusoidal the power company would like to see. A PF of 1 minimizes power distribution losses. A PF of 0.50 will quadruple power distribution losses. That’s why PearlLED designs its LED light bulbs with a PF higher than 0.95, to help you reduce your carbon footprint.
Q. What does high power converter efficiency mean to the user?
A. A good LED bulb typically contains a power converter driving series-connected LEDs with a DC current. A power converter efficiency of 100% means its has no electrical loss. An efficiency of 85% means an extra amount of 18% of energy is used up by the electronics to drive the LEDs with the same current. PearlLED electronics is virtually lossless!
Q. What is Color Rendering Index?
A. Color Rendering Index (CRI) is a number smaller than 100 indicating how close the light spectrum of a luminaire approach sunlight or black body radiation. Fluorescent lights’ typical CRI is between 50 to 75. It is very difficult for CRI of LED luminaire to approach 100. A CRI greater than 90 is considered very good.
Q. What is Color Correlated Temperature?
A. CCT is a number expressed in Kevin degrees indicating whether the light color is warm (low CCT) or cool (high CCT) and anything in between. Some people prefer warm light colors, jewelry stores typically prefer cool light color.
Q. How much money do I save per year by switching to LED bulbs?
A. There’re four types of savings: energy cost, labor cost, air-conditioning cost, and replacement bulb cost. A PAR-30 bulb used in a business setting typically runs 10 hours a day, 360 days a year, or 3600 hours a year. An incandescent bulb lasts about 1000 hours thus needs 3 replacements a year, requiring manual labor to get new light bulb and replace the dead one. At a marginal rate of electricity of $0.20/kwh, switching to LED bulbs saves about $120 a year in energy, labor and bulb cost, plus the cost of energy for cooling the heat generated by incandescent bulbs during warm months. Observe that most buildings and conference rooms have air conditioning running in the afternoons, due to heat from electrical equipment and from body heat of occupants.
Q. What is the definition of marginal cost of electricity?
A. Users are charged a higher rate once they exceed the base line, then higher again once they exceed the second threshold. Most Americans use more electricity than the base line, which is only about $30. The top marginal rate can exceed $0.25/kWh in many states, such as $0.33 in Hawaii. The cost of electricity peaks during hot summer afternoons, where the utility companies have to operate their high-cost gas-fired power plants to supply the peak loads.
Q. What about toxic chemical such as mercury found in CFL?
A. LED contains no mercury and lasts up to 20X longer. Thus LED bulbs are very environment-friendly.
Q. Do you have a recycling program for dead bulbs?
A. After their long 15-year life, you can return dead ones for recycling and actually get some credit toward the replacement bulbs from PearlLED. PearlLED recycles 95% in weight of raw materials used in its production as part of its sustainability program.
