The 37mm diameter LEDStar1 is available in spotlight and recessed formats with a single 3W CREE XP-G3 LED, that produces up to 275 delivered lumens and 10° beam with 3889 cd.

The proven technology in XP-G3 LEDs delivers best in class lifetime and long term colour stability in a compact package optimised for high CRI with high efficacy.

With a forward voltage of around 3V, up to 16 spotlights can be powered from a single LED Driver, depending on drive current.

Beams are shaped with clip-on diffusers in 10°, 30°, 80° options which can be combined with a 40° linear spread or 20° tilt.

Half blacked front glass, eyelid cowl, honeycomb louvres and half or full tube glare shield provide additional light control.

The LEDStar3 complements the LEDStar1 with three CREE XP-G3 LEDs at up to 12.4W. The thermal mass of the 64mm diameter housings allow for drive currents up to 1400mA, producing 1002 delivered lumens and narrow beam with 6777 cd.

As well as spotlight and recessed formats, the LEDStar3 is also available in Wall Mounted and a shallow Window Reveal housing which is ideal for placing on ledges to highlight architectural details.

Forward Voltage is around 9V which allows to 6 spotlights can be powered from a single LED Driver, depending on drive current.

Beams are shaped with clip-on diffusers in 10°, 30° or 80° options which can be combined with 40° linear spread or 20° tilt.

Glare is limited by setting the optics back into the housing while extra control can be provided on spotlights with additional half or full tube cowls.

For the recessed version a half-blacked glass with tilt diffuser is ideal for grazing walls and columns.

All LEDStars are available in spotlight housings

LEDStar1, LEDStar3 & LEDStar4 are also available in Recessed housings

Spotlights are supplied as standard with surface mount plate, Options available for ground spikes, tree straps and edge clamps. Also extended sign arms many of which can be customised for particular lengths

Recessed versions are fitted with rubber O-Rings to grip holes machined into solid materials, alternatively, mounting tubes are available to fix into softer materials or earth.  LEDStar1 also available with side springs for mounting through cut-outs in plaster ceilings or similar

LEDStar3 and LEDStar4 also available in Wall mount or shallow Window Reveal housings

Window Reveal housing features a shallow surface mount bracket that provides adjustment of tilt ( +/- 25) and rotation (+/- 45°)

The Wall Light version mounted on a post that conceals the cable and allows for rotation adjustment to account for misalignment or change for up/down or side lighting

LEDStar Lifetime data is derived from Cree LED’s published LM-80 data extrapolated from a series of long term test on LEDs running at different drive currents and ambient temperatures.

Lumen Maintenance: LED lifetimes are an expression of how long the LED can be operated before the output is predicted to drop below a given fraction of the original output. i.e. the lumen output is maintained above that fraction up to the stated duration. That fraction usually being 70%, 80% or 90% quoted as L70, L80, L90. For complete results the test duration is given.

In accordance with TM-21, the reported lifetimes can only be predicted to a maximum of 6 x the actual test duration. So for some configurations, the lifetime may appear shorter than for others purely due to its test duration. Where the testing has not yet indicated a drop off in output, the predicted lifetime is shown as more than (>) while for other tests the output might have fallen and a life limit predicted (=)

For example: L90(24k) > 145,00 hours shows a test duration of 24,000 hours, the output is predicted to be maintained above 90% of the original for longer than 145,000 hours.

The recommended maximum drive currents for LEDStar fittings are selected to ensure the LEDs operate below a maximum 85°C junction temperature in a normal 25°C ambient. 85°C being the test temperature for all the published technical data. Operating at higher ambient temperatures up to 50°C will have an effect on lifetime which can be compensated for by running at lower drive currents.

LEDStar1 Spotlight has a predicted L90 lifetime > 145,000 Hours in a 25° (max) ambient on a 1050mA drive current.

Or L90 > 90,000 hours at 50°C max on a 700mA drive current

Or L90 > 70,000 hours at 50°C max on a 1050mA drive current

In all these cases, the limit for L90 has not yet been reached so L70 and L80 can only be predicted to be greater than the same figure, although may reasonably be expected to be longer.

CREE XP-G3 LEDs have been subjected to longer test durations (up to 24,000 hour) than CXB COBs (12,000 hours) so predicted lifetimes for CXB COBs are limited.

Light Projects has a long history of supplying products tuned to lighting specifiers’ particular requirements.

The LEDStar range is available in a choice Standard and Custom finishes, along with a wide selection of accessories for mounting, wiring or beam shaping.

STANDARD FINISHES

Standard finishes include anodised in black, satin silver or bronze; white or black non-stick PTFE painted finishes with self cleaning attributes.  For tougher environments, Hard Anodising provides enhanced protection in a colour that varies from grey to sandy brown or can be dyed black. For special projects a marine paint and pre-treatment process is also available.

CUSTOM FINISHES

Custom RAL colour finishes are available in polyurethane powder. Various metallic finishes can be achieved with coloured anodising, plating or polishing.

CUSTOM FINISHES

Custom finishes are available, this example shows LEDStars painted to match the architectural features of the Crystal Palace subway. We also provided emergency options too.

There is a wide range of accessories available to suit the LEDStar range, including glare shield cowls, mounting brackets, ground spikes, wiring connectors, beam shaping diffusers, coloured glasses, in-ground driver chamber and many more.

Light Projects has curated a range of interior and exterior constant current LED drivers to complement the LEDStar range.

Available in a wide range of output current options to allow designers to tune light levels precisely with variants for DALI, Analogue (1-10V) or Mains dimming. DMX and wireless dimming or emergency solutions on request.

All drivers are flicker free with outputs limited to under the 60VDC SELV safety limit. Dimmable types provide smooth control from 100% to very low levels – usually under 1% and Off.

Exterior drivers are housed in IP66 polycarbonate boxes suitable for direct external use. Available with 1, 4, 8 or 12 outputs, all features top access screwless terminal blocks for serial connections and IP68 cable glands.

Driver datasheets include full information to calculate how many LEDStar fittings can be powered, maximum cable lengths and breaker loading.

Please see individual product pages for matching drivers.
