    Default LED Light upgrade

    Hi everyone

    I'm after some advice
    What will be the best led to add to the middle strip in these lights?
    I'm after something that will give off as much light as the outer 2 strips
    The outer 2 strips are the original
    The middle strip was blue, so I removed it & added these boat leds
    I don't remember what brand they are, as I've had them for years
    They are 2 foot long & I have 4 of them

    All advice will be welcome

    Hi Norfs,

    Some of those old 5050 are showing their age isn't it?

    Best to use 5630 6500K - you can use non water proof and spray with conformal coating. The world is your oyster if you want different spectrums - You can use RGBW strips if you want colour tenability. Try to use heat sink paste to stick them to the heat sink, for optimal heat removal.

    That's neat soldering on your part btw.

    Hey Rebel

    Thanks for the info & the compliment on the soldering
    Time to confess, the leds are presoldered lol

    I've used leds from strip rolls in the past & they burn out in a short time (Prob 5050)
    I have also used thermal paste to glue them
    My next question is, do the 5630 leds last or is the problem the same?

    The originals on the sides have lasted years & the strip in the middle has lasted even better, although it was never as bright

    The cause for burn out can be multiple but most related to heat and humidity. If you dim the strips slightly with a cheap inline dimmer, their longevity is extended. Use of conformal coating and extend their life. The water 'proof' silicon coating usually discolours due to age and causes annoyance.

    I have used a more expensive ($40) water proof CRI >90 strip (5m though) which has been abused without any issues but perhaps too expensive for your application.

    5630 are probably the most bright SMD LED out there but due to brightness, come with heat issues.

    3010 also is reasonable and maybe would be ok for your intentions. 5050 is medium brightness.

    I am disappointed that you didn't solder those joints. They are nicely done compared my ongoing shoddy jobs.

    Please note, my soldering is not great either

    Hopefully my last question
    Are these the leds you are telling me about?

    Yes Norfs. Those are indeed ok. And will do the job.

    I believe the best bang for buck liner LED strip is currently

    Bridgelux EB Series 159 lumens a watt.

    They only go to 5700k (This is my favourite colour temp), but a single 4000k between your current lights may add a touch of warmth.
    Cutter also do there own red/blue strips using genuine Cree.
    I find name brand to be the best for longevity, quite frankly I got sick of replacing burn out china cheapies.
