Soft Start UM2 Multi pulse fluorecent tube Lamp electronic starter

The patented Soft Start LEL Multipulse system produces timed heating followed by high energy, high voltage ignition to give very reliable starting even under conditions of low temperatures.

The soft start of UM2 and UM3 give greatly reduced cathode wear and end blackening and therefore significantly enhances lamp life. There is an automatic failed tube cut-off which avoids continuous flashing and ballast overheating.

Full range of lamps with one electronic starter

The UM2 Soft Start Electronic Multi Pulse Starter for fluorescent tubes is a soft start electronic starter and the only one which will soft start the full range of linear fluorescent tubes from 600mm 18W to 2400mm 125W, including 100W Krypton energy saver types, as well as most compact lamps. The UM2 is compatible with standard, low loss and extra low loss ballasts.

Conventional Canisters

Both the UM2 and UM3 are housed in conventional starter canisters. They have an operating life equal to that of a luminaire and can be retrofitted into existing installations of factory fitted into new luminaires.

Multi-Pulse System

LEL's patented Multi-Pulse circuit used in the UM type starters represents a significant advance in electronic starter performance. Ordinary electronic starters provide for lamp striking with one high voltage pulse each half cycle of the supply frequency. LEL's Multipulse starters provide several high voltage pulses in each half cycle. Extends the life of fluorescent tubes.

Soft Start Electronic Starter - Multi Pulse UM2

Under normal conditions a lamp will strike, after heating, on the first pulse received and further pulses are inhibited - so the Multipulse starter provides a positive soft start typical of a single pulse starter. The Multipulse advantage becomes evident under limit conditions of low ambient temperature and low supply voltage.

Where those apply the higher energy available from the Multipulse system is far more effective than a single pulse. With 2400mm Krypton lamps (100W) the higher energy Multipulse system is essential for reliable starting below +10°C, and for 1800mm slimline (70W) lamps the Multipulse starter has been shown to overcome problems encountered with ordinary electronic starters in outdoor situations.

With all lamps the low temperature and low supply voltage limits are greater than those applying to single pulse types. This also means that heating times can be optimised for normal rather than extreme conditions, thereby providing a faster start.
