LED Spotlights we introduced the advantages and disadvantages of LED spotlights compared with
halogen bulbs. The main advantages of LED spotlights are that they use as little as 1/50th of the power of halogen bulbs, and they last for years rather than months. The disadvantage is that the light they produce is not as
warm as that from halogens, they are quite poor at providing general room lighting, and they cannot be used with
dimmable light switches.
Megaman spotlights provide equivalent light to halogens, but they use 7-11 Watts of power - compared to 1-1.5 for standard
LED spotlights. In this article we will look at a compromise alternative: a 3W powered LED spotlights from
Cree.
Cree LED Spotlights
Cree Inc is a leading semiconductor manufacturer which specialises in solid state (
LED technology) lighting amongst other things. Rather than making spotlights with 20 to 80 small LEDs, their
MR16 (12VDC) and
GU10 (230VAC) spotlights are made up of three
1W powered super LEDs.

GU10 3x1W |
While the light given out by these Cree spotlights is still a lot
whiter /
cooler than that of halogens, it is not as blue as many cheaper LED spotlights, and it has a much
wider beam (matching more closely that of halogens) and is therefore much more suitable for general whole room lighting. A 3x1W Cree spotlight in low voltage or mains voltage configuration is equivalent to a
35W halogen bulb, so these can be used as direct replacements for halogens in all applications.
The average life time of a
Cree spotlight is from 30,000 to 50,000 hours - i.e. up to
6 years of continuous use.
Cree spotlight bulbs are also available in 1x5W (i.e one 5W LED bulb), 1x10W, and 7x1W (i.e. seven 1W LED bulbs) configurations offering
LED spotlights suitable for all applications.
Cool White and
Warm White versions are available, but note that even the
warm white is very white when compared to the almost yellow light of a halogen bulb.
