What is Warm White and Natural Daylight White Color for LED Light Bulbs?

Some people have asked us, how does Green Supply's warm white LED light bulb look like and the same for natural daylight white LED light bulb.

Warm white and natural daylight white is in reference to specific color temperature range. Green Supply's warm white LED light bulbs is in the range of 2800 to 3500K, providing yellowish warm white color light. Natural daylight white is in the range of 4500 to 6500K, providing crisp bluish white color light.

Warm white is the color of light generated by incandescent light bulbs and are commonly used at home for more relaxing and comfortable environment.

Natural daylight white is the color of light generated by sun at daylight and are commonly used at office and store for clean, crisp and refreshing environment.

Here are pictures of how objects look like in warm white light (light provided by Green Supply's 40W replacement warm white LED light bulbs), sunlight and natural daylight white light (light provided by Green Supply's 40W replacement natural daylight white LED light bulbs):

No More Regular Incandescent Light Bulb by 2012!

Regular incandescent light bulbs are phasing out by 2012 (for 100-watt incandescent) and by 2014 (for 40-watt incandescent). Some stores and manufacturers have already stopped selling and producing incandescent light bulbs.
On December 2007, U.S. Congress passed an act (Energy Independence and Security Act of 2007) that require all general-purpose light bulbs that produce 310 to 2600 lumens of light to be 30% more energy efficient than regular incandescent bulbs by 2012 to 2014. This is all part of an effort of being Green by being more energy efficient.

What type of light bulbs can be purchased after 2011 if no more incandescent light bulbs?

After 2011, 3 types of light bulbs are still available:

1) CFLs (Compact Fluorescent Light) for general household, industrial and commercial use.
However CFLs contain mercury, highly toxic metal, that gets release as vapor when CFLs are broken. Mercury when inhaled or ingested can cause severe damages to the brain, nervous system and respiratory system.

2) Halogen - commonly used in automotive headlamps, some desk lamps and floodlights. Halogen is not energy efficient and consume as much energy as incandescent light bulbs.

3) LED light bulbs - used for all (general household, industrial and commercial use and automotive headlamps) and are starting to even replace CFLs and halogen due to its Green qualities.

Some of the Green qualities of LED light bulbs are:

  • Energy efficient: consumes 45% less electricity than CFLs and 87% less electricity than halogen and incandescent light bulbs (based on Green Supply LED light bulbs).
  • Non-toxic: Does not contain mercury and other harmful chemicals.
  • Lasts longer, hence less LED light bulbs ending up in the landfill: At least 5 times longer than CFLs and 50 times longer than incandescent.

LED light bulb is the "Greenest" light bulb for now and our future. More information about Green Supply LED light bulbs can be found here:

City of San Jose, CA Ban Disposable Plastic Bags and Charging Paper Bags

Effective Jan. 1, 2012, City of San Jose, CA would ban single-use disposable plastic bags and stop free distribution of paper bags by retail establishments. Retailers could offer paper bags made of at least 40 percent recycled content for a charge, which would start at 10 cents and increase to 25 cents after a year.

What is Lumen?

Lumen (lm) is the measure of power of light perceived by the human eyes.

A shortcut light bulb manufacturers use to explain the light output of CFLs and LED light bulbs is based on the wattage of incandescent light bulbs that produce certain amount of light output, in which CFLs or LED light bulbs to replace can produce similar amount of light output.

Below table shows different wattage of incandescent light bulbs and light output (in lumens) these light bulbs produce (*light output shown in table is dependent on light efficiency of incandescent light bulbs):

Wattage of
Incandescent Light Bulb

Light Output

Wattage of
Green Supply LED Light Bulb

25W 250-350 3W
40W 400-550 5W
60W 700-900 7-9W
75W 900-1100 12W
100W 1600-1800 15W

Savings on Electricity Bill by Using LED Christmas Lights Versus Incandescent

Many of you are wondering, are there significant electricity bill savings by switching from incandescent Christmas lights to LED Christmas lights (turned on at most 1 to 2 months during the holiday season)?

Here is the answer based on these simple calculations:

  • Green Supply LED String Lights (10 meters (32.8 feet) with 100 LED bulbs) consume up to 5 watts per string.
  • Regular incandescent Christmas string lights consume 5 to 10 watts per bulb => 500 to 1,000 watts per 100 bulbs string lights.
  • Assume on average Christmas string lights turned on for 6 hours everyday in December and January.
  • Assume cost of electricity bill is $0.15 per kWh
  • Let's begin the calculation based on above consumption and assumption of use:
    • Green Supply LED String Lights electricity bill for December and January:
      • [5 watts * (6 hours/ day * 62 days)] / 1000 * $0.15 kWh => $0.279
    • Regular incandescent string lights electricity bill for December and January:
      • [500 to 1,000 watts * (6 hours/ day * 62 days)] / 1000 * $0.15 kWh => $27.90 to $55.80
    • Electricity bill savings by switching to Green Supply LED String Lights:
      • $55.80 - $0.279 => $55.52 electricity bill savings for 2 months!

Green Supply LED String Light pays for itself with an extra $40 in your pocket!

How to Minimize Electric Circuit Overload and Minimize Fire Hazard Risk with LED Christmas Lights?

Especially during holiday season, many homes experience electric circuit overload, which causes the fuse to blow, the circuit breaker to trip and/ or wires to overheat, which leads to fire hazard.

What is the reason for this?

The reason for electric circuit overload is having appliances draw more power from the electric circuit than what the electric circuit provides.

Typical electric circuit in residential homes provides 15 to 20 amps of electric current. The way to determine the amount of electric current (in amps) provided by each circuit is by looking at the circuit breaker box, in which a number is printed on the end of each switch to indicate the number of amps for that circuit.

One electric circuit can supply electricity for several outlets. The way to determine which outlets are supplied by the electric circuit is to switch off the electric circuit and check which outlets work or not work when the electric circuit is off.

So you are wondering, why does electric circuit overload has to do with Christmas lights?

Many of you probably don't know that regular incandescent Christmas lights can draw more power than they seem, especially when several lights run and are extended on a single electric circuit.

Here are some simple calculations to determine how many incandescent and LED Christmas lights can run on a single electric circuit (calculations do not include other electrical appliances powered by the same electric circuit):

Voltage (in volts) * Current (in amps) = Total Power (in watts)
Voltage from electric outlet (in U.S.) = 120 volts
Electric circuit provides current of 15 to 20 amps
120 volts * 15 to 20 amps = 1800 to 2400 watts of total power per electric circuit

Useable power is only 80% of the total power:
Total Power (in watts) * 0.8 = Useable power
1800 to 2400 watts * 0.8 = 1440 to 1920 watts of useable power per electric circuit

# of Christmas light bulbs that can run on electric circuit = Useable power / power per light bulb
Below table show how many regular incandescent versus LED Christmas Lights can run on electric circuit.

2.88 to 3.84 (~3 string lights)
Regular incandescent
C9 light bulb;

1.44 to 1.92 (~1 string light)

From the above table, it shows that up to 384 Green Supply 100-bulbs LED Christmas Lights can be powered by one electric circuit versus only up to 1 to 3 regular incandescent 100-bulbs string lights per electric circuit without causing electric overload.

Switching to LED Christmas Lights can help minimize electric circuit overload and minimize fire hazard risk. Here is more information about Green Supply LED String Lights:
