The BL70-LED blasting light is ideal for use in sand and media blasting applications where a powerful light capable withstanding the harsh conditions of the blasting are is needed. Producing 6,020 lumens of light output, this light has a 50,000 hour rated service life and the capability of operating with common 120-277 volt AC using the included inline transformer or 9-46 VDC without it.
The BL70-LED blasting light from Larson Electronics produces 6,020 lumens of bright light while drawing only 70 watts @6 amps from a 12 volt electrical system. Seven CREE XLamp MC-E® ten watt LEDs producing 860 lumens each are paired with high purity optics to produce a flood beam 300 feet long by 200 feet wide. We also offer a 20 degree spread spot beam configuration to produce a beam approximately 750’ long by 100’ in width. These LED light blasting lights are waterproof to 3 meters, sealed against intrusion by dust and dirt, and very ruggedly constructed to withstand the most demanding environments, conditions and applications. A single 200 pound grip magnetic base enables the operator to use the light as portable base stand unit on the floor, or they can use this LED blasting light as a magnetic mount back light.
This LED blasting light normally runs on any voltage ranging from 9 Volts to 46 Volts DC, but with the inlcuded DCP-11-DP inline transformer and 50 feet of SOOW cord, can also run from common 120V/277V AC. Operators can run these lights directly from a battery, generator vehicle, or by using the included DCP-11-DP transformer, plug this unit into any available wall outlet, 220V, or 277VAC power source.
Optional LED colors include Amber and Green for more effective light penetration in the dusty environment of a media blasting room. An integral Pulse Width Modulation controller, small profile, versatile power options, high durability and versatile mounting magnetic system makes these LED light emitters a superior lighting solution for a wide array of applications including but not limited to: sand/media blasting, military, industrial manufacturing, machine visioning, security and law enforcement, boating, vehicles and commercial structure illumination.

Heat Management: Heat is the single largest factor in premature LED failure and color shifting. These LED units contain advanced PWM drivers which use pulse width modulation to control heat buildup rather than simple voltage regulators which are typically harsh on sensitive electronics and can contribute to early LED failure. These units automatically sense the temperature of each LED and adjust the energy frequency or “duty cycle” accordingly to maintain heat levels within acceptable ranges. This system in essence flashes current at an extremely fast on and off rate to each LED based upon the LED’s core temperature. This flash rate is too fast to detect with the human eye, but provides precise control of the current flowing to each LED and thus the heat it generates. This allows the LEDs to be driven at up to 100% capacity without overheating or visible loss of light output. The LEDs are always driven at the same voltage but the duty cycle, however, is changed to alter how long the LEDs are actually on or off. The end result is more light with less heat and longer LED life with an average 70% lumen maintenance after 50,000 hours.
PWM Control: The pulse width modulation drivers in this unit also provide secondary benefits through the ability to tap into a provided input wire with an external pulse generator and adjust the duty cycle of the current being applied to the LEDs. Thus you can connect an external dimmer, switch or pulse control and adjust the perceived output of the light, effectively causing the light to flash, dim or brighten to the desired levels. Additionally, this method of controlling light output results in a corresponding drop in amperage draw, so if the duty cycle is cut back to 50% there will be a matching 50% reduction in amperage draw. These units are also able to monitor and adjust input current to maintain the correct LED voltage levels regardless of input levels across a specific range.
When equipped with the inline transformer, the LEDP10W series of light bars can operate on current ranging from 9 to 46 VDC without any modifications necessary as a result. This ability to sense and adjust input current also provides protection against voltage spikes and drops that can occur in vehicle electrical systems which would otherwise result in burning up or premature LED failure without it.
Durability: As well as unparalleled heat control, the LEDP10W series of LED light bars from Larson Electronics also offer IP68 rated construction that is designed to withstand extremes of environmental and operating conditions. These units can withstand rapid temperature changes of -40 degrees Celsius to 85 degrees Celsius, are waterproof to three meters and resist ingress of dust, dirt and humidity. The housings are formed from extruded aluminum and the lenses are unbreakable polycarbonate. The CREE XLamp MC-E® LEDs offer resistance to shocks and vibrations and are rated at 70% lumen maintenance after 50,0000 hours of use.
Mounting: This LED blasting light has a single 200 lbs grip magnetic base that can hold the unit in place even under high vibratory conditions. An integrated trunnion bracket allows operators to adjust the light through a full range of vertical movement, providing the ability to aim the light regardless of where it is mounted for best light coverage.
Note: Most Larson Electronics LEDLB, LEDP3W, LEDP10W, and LED10W series LED spotlights and floodlights are terminated with a Deutsch IPD / LADD DT04-2P connector. The mating connector plug is DT06-2S. Most LEDLB and LED10W series lights ship with mating connector as part of a harness or pigtail, depending on the model. Some larger LED lights like the LEDLB-160X2 or LEDLB-200X2 or multiple function LED lights (i.e. high/low beam, modulating, IR/Visible combos) will have different Deutsch connectors.
