A Light on the Hill

Lighting the building

This page is intended as a record of how things are done and what needs to be done. Non-electrical jobs are defined elsewhere. PA and electronic jobs are documented on this page further down.

Electrician jobs

  • Quote for “Exit signs shall be illuminated. Signage provided in accordance with the relevant Australian Standards.” (Synod 2.3)
  • Estimate for downstairs switchboard replacement with 36 or 24 way commercial board (5 June 2024)
  • North East fluorescent in hall – Northern side doesn’t work, replace entire fitting with dual globe 1200mm batten double insulated LED Warm white (2700-3000K) (current has electronic starter, discard on removal, keep globe), 2x1200mm tubes (5 June 2024)

Simple globe replacements not requiring an electrician or inadequately specified

  • Replace the Southern tower fitting on the roof of the church. Glass is broken and fitting closure is beyond repair (9 Aug 2021). Need to determine appropriate lumens for a single sided LED. Also lamp temperature (colour) to be determined.
  • The “Office” sign obstructs lighting to the steps down to the office (outside). (Sep 2021)
  • Test and inspect extension cords in use (14 Sep 2021)
  • Residual Current Devices (RCDs) and earthing cables shall be tested on a regular basis. Refer to Appendix B – Compliance Testing Schedule for frequency of tests. (Synod 2.1)
  • Electrical appliances and equipment shall be tested on a regular basis. Refer to Appendix B – Compliance Testing Schedule for frequency of tests. (Synod 2.2)
  • Exposed wiring West of PA Desk down low. (November 2021)
  • Regular testing of fluorescent light bulbs for output droop (3 May 2022)
  • Label the power outlets for Rinnai heaters “Downstairs sub-board Rinnai 1/2/3” as appropriate (8 May 2022)
  • Power factor seems a bit off. Check capacitors in sodium fittings etc on globe replacement. (27 June 2022)
  • Increase brightness on choir music, probably individual book lamps is best (27 June 2022)
  • Ministers Office, South Eastern Troffer Eastern Globe (17 Oct 2022) – slow to start (24 June 2024)

Electronics and PA System

  • Visual display unit in organ console should have sound input from either fold-back or front of house speakers. Repair or provide (28 Oct 2022).

Choice of globe

When replacing a globe, think about the following when replacing

  • Globe temperature (colour in degrees Kelvin), originally gas light is used, can’t get 1000K currently, so use the lowest possible, usually 2700-3000K.
  • LED’s are practical for anything below 4000lumen for an ordinary BC or ES fitting, specialised fittings above that
  • Lumens of globe, try and light at or above Australian Standards for the use of the area
  • Orientation of light output. Many LED globes are available with light output in one direction, this saves electricity
  • Stock on hand. Have many linear fluorescents in the tank room, use these first.

Choice of fitting

Most of the fittings were probably fitted around the time the church first got electricity around 1900-1930. Any new fittings in the sanctuary at least should be sympathetic to this and have:

  • A dark base (bakelite or brass colour)
  • Glass bulb.

Front Steps

There are three groups of lights on the front steps which provide general illumination of the front of the church and tower

  • On a streetlight a single floodlight for the upper part of the tower. This is maintained by SA Power Networks for a fee
  • Northern side of the steps an ornate Victorian fitting with
    • Internally a large LED (27W 2430lm) E27
    • A high pressure sodium globe for illuminating the tower
  • Southern side of the steps another ornate Victorian fitting with
    • Internally a large LED (27W 2430lm) E27
    • An empty fitting for a high pressure sodium globe. The fitting is rusted out and needs replacing or removing

These are all controlled from a timer that does the Roof also.

Entrance and Side Rooms

The main entrance has a fitting with three B22 candle shaped globes. One 28W halogen (oldish) and two 470lm Warm white 15000h LEDs installed 5 Dec 2024.

Sanctuary

The organ has two bulbs. The Northern one lacks two securing screws.

This has eight ball fittings, four on each side. Each one is fitted with two Bayonet globe connectors. Each has a bulbous glass globe and one or two globes.

  • Northern Most Eastern, smaller than others, Osram/Ledvance 27W 2430lm (Bunnings 0271140, LED GLOBES HIGH WATT OSRAM++27W 2430LM WW BC, Ledvance LV T 27W/827 B22D 4058075093218), purchased 19/11/2021
  • Northern 2nd from Dooletee window (East) 130 diamteter x 300mm deep, Osram 27W 2430lm, purchased 19/11/2021
  • Northern 3rd from East, 130 diamteter x 300mm deep, Osram 27W 2430lm. Glass has been repaired previously, so appears cracked close up, purchased 19/11/2021
  • Others – believed to be twin compact fluorescent globes, B22 bayonet fitting.

Underneath the balcony’s are two lights

  • Northern (Left) is a modern white Edison screw globe holder with a 14.5W, 1650Lumen, 3000K, CRI 80, photometric code 830-779, 135mA 50/60Hz 12x68mm 15kWh/1000h 113lm/W Philips 8718699640477. The fitting is original
  • Southern (Right) is original

Side of the building

On the Northern side there are two 70W High Pressure sodium. These are operated by individual photo electric cells in each fitting. As of 2021 the life of the globes has been only around 12 months instead of 4-5 years. McGuinnes agencies suggests is due to a partially failed ballast but the ballasts were all resistance tested on 20 May 2021. Another suggestion is poor handling (finger oil and Texta) on the glass of the globe.

These fittings can be isolated from the down-stairs sub-board, position 9 for North. It *may* be that when the power is restored there is a faint blue glow for about 20 seconds.

  • North East – Ballast resistance tested 20 May 2021. Globe replaced around 27 July 2021. (working June 2024).
  • North West – globe replaced and ballast resistance tested 20 May 2021. Dark again, globe replaced June 2024 (used, may be faulty, no blue glow June 2024)

These lights provide about 30lux at ground level.

On the Southern side there are two Voltex FLB-CW/72W LED fittings (72W 5700K 7900lumen). These were installed on 5 August 2021. Expected lifetime is 50,000 hours, so around 10-15 years. These are operated by individual photo electric cells (HPM Series P170) beside each fitting. They run off position 8 (office) on the down-stairs sub-board. Switching this circuit off momentarily will cause the lights to run for a minute or two.

These provide 240 lux at ground level below the lamp and 100 lux about 2-3 meters either side.

Roof

There are are, two high pressure sodium 70W lamps for illuminating the Northern and Southern aspects of the tower. On the Eastern side is a 250 or 400W Metal Halide lamp in a large fitting. These are powered from the timer that operates the front steps.

The Northern globe was changed on 20 Mar 2021, Eastern unknown, Southern is not working and cannot be opened. The Northern ballast was resistance tested to 11 ohms on 20 May 2021 and left unchanged. The Southern fitting has rusted screws and the glass shattered on an attempt to open it on 20 May 2021.

The roof and the front steps are controlled by a Schneider Electric Timer model CCT1572[0123] which switches on at roughly before Sunset and off around midnight. The timer is always kept on standard time. Will need adjustment moving in and out of summer to allow for later sunsets. The building does not need to be lit during daylight but should be light by the end of civil twilight.

Parkin Hall & Leaver Lounge

These are 1200mm 36W fluoros being phased out in favour of either integral LED battens or 14-18W LED tubes.

Music room and stairs

  • Music room is 19W 2150lm BC 29/4/2021 which gives adequate light for reading at the desk (199lux) and filing cabinets (129lm)
  • Choir Vestry is 1400lm BC which gives adequate light for the floor (71lux) and finding things in cupboards
  • Bottom of stairs is 19W 2150lm BC which gives adequate light for the stairs and lower landings
  • Top of stairs is BC gives adequate light for stairs and walkway

Downstairs Office and hall areas

These are lit with 36W 1200mm fluorescent globes of varying colours. There are many spare globes. The preference is for a 2700K (Warm White) LED globe. The tall ladder will reach the ceiling of the ministers office and other areas comfortably. The fittings in the kindergarten room have been lowered for ease of access.

In the office area use 50,000 hour LED tubes as access is difficult, never fluros or cheaper LEDs (20,000 hours or less).

The switch for the bulbous lights in the kindergarten room is between the windows of that room.

Measured light levels

At floor level. Allow a couple of minutes for fluorescent tubes to warm up. Unless stated fitting is complete with diffuser.
