4W (35W Equivalent) 330 Lumens Warm White Spotlight,PAR16 Bulb

About this product:
Our Recommended LED MR16 Spotlight bulbs are the perfect, cost effective, direct replacement for your existing Halogen bulbs. They offer huge energy savings when compared to older Halogen, and even CFL (energy saver) bulbs!

These 4W MR16 Spotlight bulbs use 16 SMD type LEDs to emit 330 Lumens of light. You would expect to see a very similar light quality and quantity from a 35W Halogen light bulb! This particular bulb provides you with a beam angle of 100 degrees, which we would class as Extra Wide. We know this light bulb will continue to provide a high quality of light for a minimum of 15000 hours, however we have seen these bulbs last much longer! To put this into perspective, we would expect a standard Halogen light bulb to last an average of 1500 hours! Not only will you save on your energy bill, but also on maintenance costs.

Dimming this bulb:
You are NOT able to dim this bulb. If you use this bulb with a dimmable circuit, you will damage the light bulb itself.

Colour Temperature

  • Warm White Warm White
  • Cool White Cool White

This Bulb's Type: Warm White

The colour temperature of the bulb is important as it changes the way the light feels. This version of the bulb is 2800 Kelvin, which translates to Warm White. The higher the Kelvin value of the bulb, the cooler the light will be. To give you an idea of the scale we use, we would class 2800K to be warm white, and 5500K to be cool white.

Equivalent Watts

We are used to interpreting wattage as an expression of how bright a light bulb is. In reality, wattage is simply a measure of how much electricity a bulb uses. The higher the wattage, the more electricity a bulb requires. As LED light bulbs are much more efficient than Halogen light bulbs, we find that they only need to use a fraction of the electricity to produce the same amount of light. We have made the comparison between Halogen bulbs and LED bulbs easy for you, by providing the wattage of a Halogen light bulb that would produce the same amount of light as this LED light bulb.

Rated Watts

The rated Watts (W) tells you how much power this light bulb uses when it is switched on. This information is extremely useful when compared to an equivalent Wattage, as it exposes the potential for energy saving.

Normally a room will have more than one light bulb, so you can multiply the energy savings by the number of light bulbs you have.

e.g. 4 × 35W Halogen light bulbs means a total power usage of 140W. When compared to 4 × 4W LED light bulbs, which equates to 16W, you can immediately see the potential for energy savings.

X

Lumens

Lumens (lm) are representative of the total amount of visible light emitted by a light source. As a general rule of thumb, the higher the lumen output, the brighter the bulb will be. A good way of thinking would be to say that lower wattage + higher lumens = better efficiency and value.

X

Intensity

Light intensity is measured in candela (cd), to allow a direct comparison of the "brightness" of different light sources. An example of intensity being useful would be to take two bulbs, one of which has a lumen output of 300, the other, 250. You could find that the 250 lumen light bulb felt much brighter than the 300 lumen bulb. This would be due to the intensity rating of that bulb being mugh higher. Intensity is normally related to a combination of a bulbs beam angle and lumen output. You will generally find that a bulb with a narrow beam angle will be more intense than a bulb with a wide beam angle (if their lumen output is the same).

X

Voltage

This is a measurement of the volts required to operate the bulb. The required voltage for MR16,GU5.3 light bulbs is 12. If the bulb runs on 240V it should be a direct replacement for your existing bulbs, with no changes required. If the bulb runs on 12V, it may need an LED compatible driver/transformer, as your existing driver/transformer may not be compatible.

X

Beam Angle

The beam angle of a bulb is used to explain how wide the light is spread from the bulb itself. Generally speaking the wider the beams angle, the softer the light will be.

Wide beam bulbs are more effective at lighting general living spaces, bedrooms or dining areas where softer light is required.

Narrow beam angle bulbs are more appropriate for highlighting areas of interest or worktops.

Base Fitting

This code tells you what kind of fitting the bulb is made for. This is key information, in order to purchase the correct light bulb.

X

Bulb Shape

The bulb shape is a further piece of information to explain the general shape of the bulb. Normally this refers to the glass/lens of the bulb.

X

Diameter

This is an important piece of information which allows you to make sure the bulb will fit into your existing light fitting. In the vast majority of cases our bulbs are retrofit, meaning they are a direct replacement for the Halogen equivalent.

X

LED Quantity

LED (Light Emitting Diode) quantity is literally the amount of diodes a bulb has. This is more of a "nice to know" piece of information, as there is little correlation to light quality or output, and number of LEDs.

Normally you will find that a bulb with a higher number of LEDs will have smaller LEDs, and a bulb with a lower number of LEDs will have larger LEDs.

There is normally a correlation between size of LEDs, and achievable light output; the larger the individual LED, the more light it can produce.

X

CRI

Colour Rendering Index (CRI) uses a measurement scale from 1 – 100. The closer the score is to 100, the better a light source is at representing an objects true colour. Natural light sources such as the sun are the best at representing an objects true colour with a score of 100. Artificial light sources can range from negative numbers, right through to the perfect 100 score.

X

Case

This shows the material that the majority of the light bulb casing is made from. This material is important, as it plays a key part in dissipating the light bulbs heat.

The more efficient the material is at heat dissipation, the less heat builds up in the light bulb, and the longer the light bulb will last.

It is a common myth that LED technology generates no heat; however, it operates much more efficiently than its Halogen equivalent, and therefore runs a lot cooler.

X

MPN

MPN stands for Manufacturers Part Number. This can be useful when comparing like for like products.

X

Dimmable

This is simply whether or not this light bulb can be used with a dimmer switch. If the LED light bulb is classed as dimmable, please make sure you have a trailing edge dimmer switch. This will allow the dimming functionality to work as intended. If you have a leading edge dimmer switch, you may experience an erratic output from the LED bulb. Light bulbs that are dimmable can always be used on a non dimmable circuit. Light bulbs that are non dimmable, can’t be used on a dimmable circuit.
