Low-cost safelighting
I have bought and tested some red LED 'golfball' bulbs, about 45mm dia with ES caps. They cost £2.50 each and they are genuinely safe for 10mins at 2m. I even considered putting one in a desk lamp over the dev dish but it would have needed an adapter that I didn't have - I've not seen them with a bayonet cap.

Surprisingly there are no China or HK sellers, so the cheapest seller is in the UK, at £3.99, incl. p/p, BUT, they don't have stock of red at the moment! https://www.ebay.co.uk/itm/1W-B22-mi...IsgFiv7f6OwO2w The next cheapest is £4.95, incl. p/p: https://www.ebay.co.uk/itm/Colored-L...AL-s-gBVuMqSeQ But I bought a similar screw bulb to you, (at 99p incl. p/p from China!) and it needed an adapter, but that turned out to only cost a few quid on ebay.

Lidle super market at this moment are selling a light bulb that can be all the colours of the rainbow it has a remote control to dim the light or change the colour or to switch it on or off. Sounds promising for a safe light when in RED mode. £5 . I will try and pick one up and try it as a safelight for B&W, having a remote control is a great feature. The Lidle bulbs are screw fitting but Ebay has a massive variety of rgb bulbs for sale.

Tested the Lidl RGB multi coloured bulb switched to RED on full brightness 1.5m from my easel. Exposed Ilford mg1v for 10 mins, absolutely no fogging of my paper. The bulb is LED 7w thats 60w old school bulb wattage. The ability to switch the bulb from red to white by remote control or on/off is a good feature to have.

Currently I have a 25W clear bulb in an Ilford 902 safelight and the light is quite good but an open 60W red incandescent in my darkroom would would be incredibly bright It's certainly tempting Mike |

The 7W will refer to all LEDS on - the bulb will be either 3 LEDs (Red, Green + Blue) or 4 (RGB + white). The red will likely be 1 or 2W. Still plenty of light in a small darkroom.
LEDs should last a very long time - it tends to be the power supply that goes first in LED bulbs or poor design/cost-cutting leading to overheating. Last edited by Bob; 11th February 2020 at 09:04 PM. |

Yes the red led light appears a little brighter than my old Paterson safe light.
