ABL Lights – efficiency and durability
France ’ s ABL Lights was founded as Auteroche in 1875 and is now part of the global Vignal lighting group headquartered in Corbas , Lyon , operating as Vigal ABL and based in Caen . Mining is one of its major markets where products include ABL 500 LED series work lights which “ are designed to exceed everyday demands in all applications . Through stringent engineering and testing practices , we ensure the highest efficiency and durability in even the harshest operating conditions .”
The ABL LED3000-500 Series is cited as an ideal work light for mobile plant and equipment offering an exceptional output for such a low wattage fixture , with six LEDs producing 3000 effective lumens from just 36W . Compact and lightweight with class leading EMC and IP ratings , the LED3000-500 is available in 24V DC only and multi voltage configurations with wide flood , flood , flood asymmetric and long range beam patterns . “ Ideal for the harsh operating conditions found in the mining , construction , forestry and agriculture industries , the fixture also comes with the option of a warm white colour temperature that is ideal for foggy and dusty environments .”
For the same product range , ABL has released a new flood asymmetrical light pattern dedicated for the applications where close range and extra wide angles are needed . This specific light pattern allows an increase of horizontal and vertical spread which provides more visibility , safety and comfort for close
maintenance due to longer life . “ G & G ' s 1 " round lowprofile luminaires are ideal for mines due to their unobtrusive form factor which can be easily mounted even in areas with spatial constructions . They are IP68 rated against moisture and dust intrusion , IK07 / IK10 rated against impact and 3G vibration tested . Incorporating the latest in LED technology , they pack a punch at up to 20,000 lumens / 2,000 lumens per foot with an incredible efficiency of up to 160 lumens per watt .”
MineARC ’ s comprehensive and intelligent line-up
MineARC ’ s lighting solutions span across cap lamps and smart mine lighting , linked by its own intelligent network . The SiriUS-LUX Cap Lamp features two unique beams ; working in tandem to deliver a better field of vision for personnel . A
range demanding applications or specific low height positioned lamps .
Other mining solutions include the 2500 Series ABL ( 5 ” x5 ”) Halogen work lamps which it says have long been the OE standard for a wide variety of heavy equipment . ABL has now launched the new ABL LED5000 series . “ The ABL LED5000 draw 2.4A at 24V ( 57W ) yet it outputs an impressive 5,000 effective lumens . 2.5X more effective lumens than your standard HID Xenon work lamp . Class leading surge protection , protected lens and IP69K sealed electronics make this a superior low draw , high output rugged work light . ABL LED5000 comes with the heavy-duty AVB bracket as standard .”
ABL LED3000 500 Series LED Work Lights on a mining truck high-lux , intense spot beam provides focus , while a lower-lux wide beam provides a more dispersed , further-reaching flood light . The dualbeam operation ensures a crisper and more natural light is projected , with various mixed beam options available .
The inclusion of a ‘ BOOST ’ mode allows for short-term , high intensity LED light . BOOST mode provides a powerful light for a short period of time if required , without completely draining the battery . In addition , ' ATTENTION ' mode results in a continuous light pulse ; designed to provide a clear visual alert .
The SiriUS-LUX Cap Lamp boasts an impressive improvement to the Colour Rendering Index rating . Colour Rendering Index ( CRI ) measures - on a scale of 1-100 - the ability of a light source to accurately render frequencies of the colour spectrum , compared to daylight . Existing cap lamps in the market have an approximate CRI of 70 colour accuracy , however SiriUS-LUX features a CRI of over 90 . This improved CRI rating allows for a more comfortable user experience . This is most beneficial to those relied upon to detect subtle changes in colour , such as those in the geology or electrical field of work . SiriUS-LUX aims to emulate natural daylight as closely as possible .
These lamps also perform a tracking role . MineARC ' s Tracking Technology has been specifically developed to integrate with the GuardIAN Intelligence Network , allowing sites to remotely monitor the location and well-being of all underground staff . A small tracking chip located within MineARC ' s personal devices ( such as the SiriUS-LUX Cap Lamp and Aura-PT Handheld Gas Detector ) communicates via wireless technology with the nearest GuardIAN Node , providing location information back to the GuardIAN Network . GuardIAN Tracking Technology is particularly useful during an emergency scenario ; providing navigational assistance to safe passage or the nearest refuge chamber .
The SiriUS range is an alternative LED cap lamp range , available in a cordless or corded model . Available in a distinctive yellow design , the SiriUS Cap Lamps offers two unique beams working in tandem to deliver a better field of vision for personnel . The dual beams offer a crisp , natural light across high-lux spot beam and wide-reaching flood beam lighting combinations , with a battery duration rated for 15 hours .
In response to client requirements for cost reductions , greater efficiency during maintenance runs and improved operational safety on-site , MineARC has developed a suite of technologically advanced products , collectively known as the GuardIAN Intelligence Network . Designed to provide integrated , site-wide intelligence through diagnostics , tracking and
