    That’s for the 50w version I’ve got the 40w which only puts out a measly 4800lm

    T8 replacement led tubes, used in offices, are a bit more efficient 24W->3700lm, but unfortunately seemingly ~£20 non-commercially ...upfront, leds ain't cheap

    still looking for high lumen led rx7's uplighters though

    Ah, noted! Thanks.

    Oops, forgot the obvious - yep non-dimmable.

    - Non-dimmable GU10
    - 3/4/5W (about 350-400 lumens)
    - Warm white (about 3000K)
    - Wider beam angle (> 60 degrees)

    I would consider the ones from TLC direct, but they seem quite expensive (10 for £45 inc VAT).

    you can find smd ones which look physically the same on alibaba (foxconn) for £2 .. but i've had failure on other bulbs from alibaba so am more of the mind pay more and have a minimum 2year guarantee - alibaba maybe 2nds from factory

    those led's also use a more recent , more efficient chip 2835

    I currently rule out both osram and philips gu10's due to dimming reputation, which is probably indicative of non-dimmable quality,

    .. Hyperikon had 5year guarantee, they went, in the more closed bathroom fittings, probably poor bulb heat dissipation. ... need to judge bulb quality by the weight of metal for heat dissipation

    just bought two of the 4ft ones for my double garage might do a before and after comparison. currently its got some old florescent tube lights and an 10w LED floodlight aimed at my work bench but if these are as good as they sound I may be able to move that floodlight somewhere else

    Well I brought a different style twin T8 tubed battern which I got around to fit today.
    https://www.ledhut.co.uk/commercial...ts/ip65-4ft-1200mm-with-pc-diffuser-twin.html

    Which has 2 of these tubes. https://www.ledhut.co.uk/commercial...e-lights/st8p-1-2m-16-2w-865-220-240v-em.html

    The V-tac one is without a doubt brighter which my mrs also agrees, I wired them into 13amp plug sockets in the front room and you can notice quite a difference.

    So I mounted the twin tube to the ceiling in the garage and it seems to do a better job at lighting the garage than the V-tac which is strange because as I said it without a doubt throws out a brighter light, the only difference I think is that the twin tube has a wider beam angle so it throws the light out further either side.

    Which one did you get 40w or 50w? I’m not sure if two will be enough for your double garage but one seems to do the job in mine and two will light up the whole garage very well. You may need an extra or 2.

    All in all considering the price of the V-tac im still quite amazed at the amount of light it puts out for the price and wouldn’t hesitate to buy more in the future.

    I'm running Osram GU10 and they dim much better than my previous bulbs, I'm really happy with them. They are 7.2w, specifically part number 4058075056664. I paid just under £5 each but that shop no longer stocks them.

    interesting - with a varilght vpro ?

    earlier post i made

    I subsequently looked up the philips t8 price from my post
    https://www.any-lamp.co.uk/philips-...master-daylight-incl-led-starter-replaces-36w
    2 - 4' tubes 5000lm £10each - cheaper than i thought.

    Yes with varilight, they have a fantastic range, from barely on to very bright.

    Thanks for the info I went for the 40w ones, currently the tubes i have are fitted at 90 degrees to the rafters so they span around 4 rafters my plan is to put up some 9mm osb and paint that white and then run the two vtac lights parallel to the rafters so i could in theory fit another two in easily but will decide on that once I get them up and running.

    So installed the two I got just roughly for the time being. They are currently in the middle of the double garage and I think your right I will be ordering another two as using two centrally the corners of the garage are a little dark so two per side is the way forward i feel. Also will get some scrap ply to mount them to as they do flex a little

    So here is a quick video of two of those V TAC 40W 4800Lm led lights installed in my double garage. They replaced two old 70w T8 tubes. I'm happy for the time being with them although i think i will add a third in and make them run parallel with the joists by mounting them on so ply or something. Video shot and edited quickly on phone so not the best I'm afraid also excuse the messy garage after 6 months we still havent sorted out all the crap from the house move

    afaik , so you can re-use an old t8 fitting with a led, it's just a placebo, filling the old starter place ... I hadn't appreciated you, indeed, replaced t8 fittings

    edit: fix maths
    so had 2 of these gu10 hyperikons fail after 14 months, and then a 3rd last night in the kitchen, 2weeks later.
    They have different usage patterns, kitchen probably seen 3000 hours, switched on most of evenings ... bathroom much less, turned on 'occassionally'

    so do they fail based on switch-on events or power on hours ? regular amazon price was ~£2.50

    after discussion on v-tac brand, seems they have two year warranty, and are also sold by CPCfarnell,
    where you can buy a few bulbs in small quantities from different makers, P&P more reasonable than most too.

    for gu10, saw these interesting comments about wide 110degree angle smd bulbs, which I had not considered, cheaper to manufacture with no optics, and may glare too.
    so will probably stay with narrower focussed <40degree spots for kitchen/bathroom ?
    eg https://cpc.farnell.com/v-tac/166-vt-277/lamp-led-7w-gu10-4000k/dp/LP11397

    I would like these https://www.v-tac.eu/led-lights/lig...0-plastic-lens-cover-4000k-cri-95-detail.html
    but cannot find a uk seller ?

    I've heard that transformers meant for halogen 12v lamps can cause their LED equivalents to fail prematurely, or flicker, is there any way to know if my transformer is OK to use with LEDs?

    Me again, having found some MR16s, I want to replace the ES bulbs in my dome ceiling lights, the problem is normal LED bulbs look stupid because of the large collar you typically have which creates a big shadow in the dome, what other options are there?
