LEDs lamp.

[mottofreee]

Stop lamp was always problem - blown bulbs. LEDs last much longer (50 000 hours) than filament lamps (2000 hours).
Pt bottom lamps are LED bulbs for granted but must be made up.

I bought it and red LED's for: https://plus.google.com/photos/11282...56747093784162
- Dismantled bulbs
- LEDs connected in series
- Mounted LEDs
- Glueing LEDs with silicone.

Next , buying a current sources for LEDs.

Seems like a lot of hastle. I just fitted 286 LED bulbs, that way when one fails I can easily replace it.
I also found white LED's showed up better than red ones once the cover was put back on.

Reasoning using red LEDs is as follows:
Why put an LED that emits relative all spectrum if only the red it is used? Lens lets passing than red. Suppose only Red, Green, Blue; R is ok, G and B is cut.
My goal is and reducing energy consumption.
This is only one step.
I used this type of LED into an application full of stress (mechanical vibration, electrical noise, voltage fluctuating ,temperatures from -10C to +40 C) and the results the two year of operation are positive
Power consumption Initial is 10W with 17lm / W but LEDs are 100lm / W => 17/100 = 10 / PLED => pled = 1.7W.
If Uf LED = 2.1V => If LED = 1.7 / 5 / 2.1 = 161mA.

[Mr T]

I understand you want to save energy & like you I've changed some of my bulbs over to LED.
But if one of your LED's becomes faulty, how are you going to change it as you've glued them in?
I went the route of LED bulbs for this reason, as over the years I've had a few LED's fail.

These are the type of bulbs I used.

Sorry the photos are so big!

These Led's give a good spread of light & are a lot brighter than the bulbs they replaced.
I'm guessing at the power they use.
Each SMD approx 30mA, three per bulb = 90mA, Five bulbs = 450mA, which is quite a saving on the original bulbs but not as much as your set up.

The LEDs used by me are used in 67% of capacity in the configuration presented and will last longer than Smart ... theoretically and practically.
In addition ,LEDs used in LED-bulb it is using a 100% +; therefore burn.
From my practice 15 years power LED
any LED bulb (commercial) has life time like filament bulbs, for economic reasons.
Indeed it is difficult to construct the lamp if the elements are ready but more beneficial , MTFB of which is primary.

I've only had one blown top brake light bulb in 15 years of Smart ownership.

[mottofreee]

I have changed in two year two top brake light bulbs.
The voltage is the same and the brake lights down, light up synchronously.
The bottom line is that I walk with Smart unloaded. Or bulbs that are found here are of poor quality?
Finally, I finished and mounted the lamp.
Looks like this :

Just bought ten 286 T5 LED bulbs on eBay for £1.97. Looks similar to those fitted by Mr T. Comes all the way from China so no chance they'll arrive this year.

Ebay ad says "Low power consumption, save your power supply.
LED Q'ty: 3LED Voltage: DC12V Wattage: 2W"

Errrm a standard filament 286 is 1.2W lol

[tolsen]

Do not believe the Chinese. No way can the tiny LED bulb draw 2 watt. Its resistors would burn out because they are too small.

[tolsen]

Mine will draw less power than Mr T's because 220 Ohm resistor as opposed to 100 Ohm on his. The only worry is perhaps his is brighter.

[Mr T]

Looking good, I love people doing modding. Gives me ideas for other projects.
