Research on Led Theatre Lighting

LED SPOT Lighting for LTC

Doing more research this morning on replacing the older expensive globes with LED bulbs, allowing the old, theatre lamp cases to be used. The blown bulb I picked up from the Theatre has a P28S bayonet base. This is only used in Navigation Lights and very old theatre lights.


Replacement bulb costs:

$20 for 100 Hours of life!

To keep the case, I researched buying a DMX512 receiver and 20+W White LED then building our own. While this will work, the cost in labour is too high at this time.

The Original research on PAR64 LED Lights was around colour effects and basic lighting only. Not Flood. Hence our current LED lights provide nice effects on stage, however they are not useful for direct lighting. Technology has moved forward since the original LED light purchase and we now have have available RGBW Lights as standard. These come with Red, Green, Blue and White LEDS to provide White and allow tinting by turning on Red and Blue.

Cheapest Option I’ve found is:

Its the cost of 3 replacement globes. To put it into perspective.

While this light will never match the warmth of the current lights. It is a good stepping stone for replacing the lights that are more for spot lighting. Plus this is considerably cheaper than any commercial LED light that will match the colour temp and functionality of the Warm Lights we have now.

I recommend not purchasing replacement spot bulbs where possible and purchasing 2 of the above for trial and use.

For general Stage lighting, the Flood Lights will be useful for many years. The bulbs are cheap (under $10) and last hundreds of hours. It will be a long time before we can warrant the cost to replace them.
