    LUM-INTENSETM by ActiveLED® is a new LED luminaire lighting technology that provides more light (more lumens per Watt) and less glare - punches an intense amount of light out of a smaller package.

HMT Series ActiveED® High-Mast Tower Light includes a 10-year no light-loss warranty and is a 175 Watt direct replacement for 1,200 Watt Legacy bulb fixture

HMT Series of ActiveLED® High-Mast Tower Light for illuminating Parking Lots, Pedestrian Areas, Property Perimeters and Overpasses on High-Mast Towers of 100' to 150' in height. The HMT Series Fixtures provide crisp bright lighting to replace legacy bulb-technology MH and HPS luninaires.

The ActiveLED® HMT High-Mast Tower Light Light consumes 70 percent less energy than conventional lighting and additional energy savings can be achieved with the optional lighting management.

The HMT-Series are the lightest by weight, passively cooled High Mast light fixtures in the market with a system efficacy of more than 150 lm/Watt within its full operating range of -55°C to +60°C.

Because they are passively cooled, which means no fans or other mechanical parts are involved in the cooling process, there is nothing that can fail.

With its patented design and superior LED elements, the ActiveLED HM Tower Light is a reliable light source with a warranted 90,000-hour lumen life, making it a nearly maintenance-free solution for applications where changing bulbs and ballasts can be hazardous and expensive.

Fraction of conventional lighting costs and very low maintenance cost. Anti bacterial and anti fungal coating.

The ActiveLED HMT series high-mast tower lights employ separate Driver / Electronics that can be installed with the light on the top of the mast or remotely at the base of the Mast / Tower for ease and convenience of maintenance.

ActiveLED HMT series high-mast tower lights are an opportunity to convert to environmentally safe and energy-efficient LED Lighting.

One of two beam angles can be specified with order 45° or 60°. The beam angles are +/- 22.5° for the 45° beam output and +/-30° for the 60° beam output.

All the available light from the HMT fixture is directed onto the lighting target and the employed technology delivers very precise light cut-off, virtually eliminating any light polution and overspill.
