Has anyone used these guys for LEDs?

The prices they have look good in comparison to Bebi and Sensi Bulb (about $40 US each). I was looking at whether it was worthwhile figuring out how to make them myself and buying the components to make them myself when I came across this site. I know both Bebi ( http://www.bebi-electronics.com ) and Sensi Bulb ( http://www.fourwinds-ii.com/v2/?c=ledinterior&i=002 ) are very good from all the first hand reports I have read. This was a very good comparison that someone went to a lot of work to do http://ssca.org/phpBB3/viewtopic.php?f=4&t=7969&hilit=sensi+bulb&start=45 .
I have some cheapo LED bulbs that I bought about 3 years ago and they were crap, fading out within a year. I don't want to buy crappy LEDs again.
 
As Leds tend to be very long lasting, and MR16 Led arrays have multiple leds anyways I think the chances of duff product is very limited. I replaced tunsten bulbs with MR16 fittings in 2004 and a few are still MR 16, but the majority are MR16 leds, which are fine for most general purpose stuff, except (for me) reading. My wife is quite happy with Leds for reading. As the power consumption is 5 times lower, both in energy terms and also in load on the wiring, they are definately the way forward.
 
After posting I looked at the site, and the product does seem to be expensive, when Amazon and Ebay sites are offering MR16 led arrays from £3.50 to £5.00.
Maybe buy a sample and see if worth the money?
 
There was a firm from Rochdale at a recent boat jumble, very extensive range of LED lights, inc nav light arrays. Sorry can't remember their name but worth Googling for.
 
Thanks for all the suggestions, but I am looking for people with first hand experience with good quality LEDs. I want good quality replacements at a good price. I am currently throwing out 8 cheapies that didn't last, LEDs are supposed to last for 50 000+ hours, I got less than a year out of these.
 
I beleive that the life of LEDs is quite voltage sensitive. If you expose an LED to more than about 13.5V you will reduce its life quite considerably. Given that we charge batteries at something over 14V this is almost certain to occur on a boat. The solution is a cheap voltage regulator. I must fit one myself.
 
Turtleback, I think you are absolutely right, I believe that is why my previous LEDs didn't last. I have also heard that there are different grades of LED's with the same spec's.
Tommyrot, I have heard nothing but good stuff about Bebi and they are on my short list at the moment. They do some good fluoro replacements and some great external lights. I haven't seen a direct comparison yet, but I have a feeling that the SensiBulb may be a better halogen replacement. It's a pity that there doesn't seem to be some competition here in the UK.
Most of my info has had to come from overseas sites :-(
 
Ordered some to try.

I ordered a couple of LED's from Bedazzled to try. I didn't realize when I ordered it that I would have to do a little wiring as well. The light came with a couple of little components that it calls a transient suppressor circuit. I am just trying to identify what they are and why they were used rather than a voltage regulator(LM2940 as was suggested by someone here). Any ideas?

The diodes has 1.5KE 30CA CHN817 on it, the other item has 72 XF065 on it.
Thanks
