Terminology Information
Lumens (lm)
Lumens is the standard by which the amount of brightness /
light emitted by a light source is measured.
lm/w
This calculation denotes the amount of lumens emitted per
watt of electricity used.
WATTS (W)
The watt (abbreviated W) is the International System of
Units' (SI) standard unit of power(energy per unit time), the
equivalent of one joule per second. The watt is used to
specify the rate at which electrical energy is dissipated, or
the rate at which electromagnetic energy is radiated,
absorbed, or dissipated.
EQ.WATTS
This equation is used while shiſting from an old lighting f
ixture and replacing the same with an LED f ixture, hence
the shiſt can be made based on the Wattage of lamp
requirement.
Voltage / Frequency
Voltage denotes the electric power required for the effective
working of the said product and frequency denotes the
Horse Power of the said product.
CRI
The Color Rendering Index (CRI) is a scale from 0 to 100
percent indicating how accurate a "given" light source is at
rendering color when compared to a "reference" light
source. The higher the CRI, the better the color rendering
ability.
PF
Power Factor is the ratio of the actual electrical power
dissipated by an AC circuit to the product of the r.m.s.
values of current and voltage. The difference between the
two is caused by reactance in the circuit and represents
power that does no useful work.
Beam Angle
A beam angle refers to the angle of light produced by a light
source.
RECESSED
A recessed light or down light is a light f ixture that is
installed into a hollow opening in a ceiling.
SURFACED
The f inished housing is exposed, not flush with surface.

IP RATING
IP Ratings (Ingress Protection) A two-digit number
established by the International Electro Technical
Commission, is used to provide an Ingress Protection rating
to a piece of electronic equipment or to an enclosure for
electronic equipment.
Here are some of the easy to follow references to help you
decide which IP Rating you need or have.
IP20: Not protected from liquids.
IP44: Protected from water spray from any direction.
IP45: Protected from low pressure water jets from any
direction.
IP65:Protected from low pressure water jets from any
direction and dust ingress.
IP66:Protected from high pressure water jets from any
direction.
IP67:Protected from immersion between 15 centimeters
and 1 meter in depth.
IP68:Protected from long term immersion up to a specif ied
pressure.
5050/30
A number that signif ies the size of the chip and number of
chips on the LED strip where 5.0mm x 5.0mm being the
size of the chip and 30 being the number of chips in one
metre length of the strip.
5050/60
A number that signif ies the size of the chip and number of
chips on the LED strip where 5.0mm x 5.0mm is the size of
the chip and 60 being the number of chips in one metre
length of the strip.
5630/60
A number that signif ies the size of the chip and number of
chips on the LED strip where 5.6mm x 3.0mm is the size of
the chip and 60 being the number of chips in one metre
length of the strip.
5630/72
A number that signif ies the size of the chip and number of
chips on the LED strip where 5.6mm x 3.0mm is the size of
the chip and 72 being the number of chips in one metre
length of the strip.
3528/60
A number that signif ies the size of the chip and number of
chips on the LED strip where 3.5mm x 2.8mm is the size of
the chip and 60 being the number of chips in one metre
length of the strip.
