Take your eye off the light and it keeps getting better…LED bulb development

Believe it or not this is an LED candle bulb. Looks like a filament bulb but its only 2.2watts. The heat sinc part of the eddison screw (the bottom bit for the bulb) is much smaller than anything else i have seen. Not sure if they are dimable but does not really matter for us

On a visit to the Wallace collection in London last week as part of our work with the Fit for the Future Network we were introduced to a new LED candle bulb, which uses linear COB (Multiple-chips-on-board) LEDs to look like a tungsten filament.  It was ‘like’ at first look….and this is the strength of the sharing network. We were there to help but the NT might have gained a new opportunity as well. Early days but first impressions count for a lot. This one I got from B&Q earlier today for £6. From what i understand the use of the liner chips and a vacuum inside the bulb glass increases the lumens per watt (amount of light) and reduces the heat generation. The warranty is only 6000hrs, colour temp is a warm 2700k, 360 degree beam angle on this bulb. (loads out there and some claiming 50,000hr lifetime from well-known retailers)  All this needs testing. But on looks and predicted performance things are looking good. But we need to test quite a few more attributes to make sure

The Jones family lighting. Old style (feels weird saying that) anf the new bulb in the front. Initial completely subjective view. More light for less energy. took both bulbs out and the new bulb is much much cooler in terms of heat.

The Jones family lighting. Old style candle LED at the back and on the left (feels weird saying that having seen it develop) and the new bulb in the front. Initial completely subjective view. More light for less energy. (more efficient) Took both bulbs out after they had been on for 10 mins and the new bulb was much cooler in terms of heat. Usually means more of the electricity is being turned into light and not being wasted through the generation of heat

This was the one we were directed after our visit to the Wallace collection. It just looks right. But only 1W (120 lumens) means a specialist use.

  1. This new LED candle bulb is different from all other LED bulb. I think more tests need for this bulb. I am waiting for next test result….
