Simmonsigns Pulsa 4004

As received, this Pulsa employed two 60 W GLS lamps, but these lamps were changed to 7.5 W LED GLS lamps in 2019. Simmonsigns produce a dedicated LED version too, although this features LED clusters, rather than retro-fit lamps. Aluminium cowls are fitted above each lens, in order to concentrate both beams.

Two tri-head bolts are located on the back of the fitting, and secure the hinged front section to the fixed back section. A SELC controller unit operates the flashing sequence for a programmable length of time; this also incorporates the radio receiver that allows the flasher to be operated by remote control. A 'checked' sticker on the internal steel plate suggests that this fitting was made in 2001.

Two 76 mm u-bolts clamp the fitting to its pole.

The remote control allows both manual 'on' and 'off' operation, though the fitting will switch itself off automatically, if left on for the pre-programmed operating time.

The SELC 860DR flasher unit is removable, allowing rapid replacement in the event of a fault. The black switch located bottom-left is another means of switching the load on or off, whilst the programmable timer is located bottom-right - this ranges from one minute to two hours. Currently, it is set to (approximately) 30 minutes.

The video below demonstrates the Pulsa's operation, along with that of my 11 W Refuge Beacon:

Testing with my energy monitoring device revealed the following results:
