    LED Hut have once again extended their exclusive 20% off all spots and bulbs offer until the end of May.

    If you want to save 90% off your energy bills by making the switch to LED lighting, now is a great time to do so.

    Simply click the banner below and enter the code LEDRF20 at the checkout to get a massive 20% off all LED Spot lights and bulbs including GU10′s, MR16′s, B22′s and ES fit bulbs.

    Don’t forget, they are now selling 5 watt GU10′s with a stated 460 lumen output. That’s possibly the highest output from any LED on the Internet and reports on this forum are that they work beautifully with LightwaveRF dimmers.

    Regards
    Chris

    And I was all set to buy the £3 LED bulbs from eBay in China until I saw this… you shouldn’t show me shiny things, it’s bad for my bank balance!

    On the plus side, I’ll be all Lightwaved-up by the weekend – which in many ways is unfortunate, given a couple of weeks ago I only started looking at Lightwave because I wanted to be able to turn my fountain on without going into the garage! ;o)

    Just a bit of feedback about the LED Hut 5W GU10’s…

    I’ve got them in my living room, kitchen and bathroom now. In the living room (x5 lights) and kitchen (x4 lights) they’re great. However, I’ve noticed in the bathroom (x4 lights too) there is an almost imperceptible flicker when they are dimmed. You can’t tell by looking at them, but I get essentially a “flipbook” effect when things are moving quickly – running water being the obvious one. Basically, rather than seeing a smooth water flow, you can see the individual droplets frozen by the strobe effect. Like I say it’s very subtle and won’t bother most people, but is something to be aware of. I also notice it if i turn around quickly, which is more of a problem (but less easy to clearly show) than the running water effect.

    Note that it may also happen in the living room and kitchen, but I don’t dim the kitchen lights and nothing moves quickly in the living room, so haven’t picked up on it yet.

    Interested if anyone else can replicate the same effects with those bulbs…?

    I’m guessing this effect could be a result of Pulse Width Modulation. One way to dim LEDs is by switching them off and on faster than the eye can actually see. The longer the led is on in the cycle, the brighter it appears. The disadvantage with PWM is that at certain frequencies (dim levels) a flickering effect could be seen.

    Finally bit the bullet and ordered 26 GU10′s from ledhut. Half cool & half warm white.

    Apart from sorting dining room E14 golf ball bulbs, that’s the whole house converted to LEDs!

    I clicked the banner above, so assume that tracks through to LedHut and they know your the referrer chris?

    Thanks for sorting the discount, made it a little easier on the wallet! ;-)

    Assuming it was you who bought the 4.5 watt GU10′s (13 of each), then yes, the sale has tracked. Thank you very much. :-)

    Just be careful because testing with one bulb on a multi light circuit might not show final results.
    I have one circuit with 3 LED bulbs that flicker and dont turn off, but if I replace one bulb with a normal halogen bulb its fine.
    (3 x 3.5W E14 SES bulbs = 11.5W)

    Hi Chris

    Thanks for the reviews and comments about using LED with LightwaveRF.

    I bought 24 SMD LEDs from LEDhut but I have to say, I am not impressed with the lower brightness range of what I have received. My wife andI like to chill at the end of a day with a movie turning the lights down low accordingly. But I don’t seem to manage to dim lower than what you’d get a from a conventional brightness (even when combined to add load).

    Can you help?

    I contacted LEDhut saying perhaps I had purchased the wrong product and should I exchange. They said it was probably the lightwaverf causing the problems and I should buy a trailing edge from them. I said lightwave (quote) “use trailing edge technology”. I told them I would be happy to swap bulbs to another as I had read you positive review and was confident that other products would probably dim lower but the Rep said that all their products had essentially the same technology and no point trying another product. So they are boxed up and have agreed a refund.

    Can you tell me (from your experience), will I find bulbs to dim down to the required ‘sexy, romantic level’ or is this a general limitations of the combination of the technologies? If this can be resolved, please could you indicate which bulbs I should try next. Also, my general suggest would be an indicated specification of a ‘Lumen range’ for dimmable LED, if this is a common occurrence.

    Cheers

    Dom

    I think your issues are actually more to do with LED than the LightwaveRF dimmers. From my experience, while dimmable LEDs do get er dimmer, they don’t go that warm orange colour of dimmed halogens, they just get less bright if that makes sense.

    This is a limitation of the LED technology I think and until some bright spark comes out with a dimmable LED which mixes colours in varying degrees to match the effect of halogens, this will always be the case. You must remember that light from halogens is actually a side effect of heating a wire. Light from LED’s is a side effect of passing an electric current through a chemical and to dim it, it just switches on and off faster that the eye can see. The chemical will always react in the same way and therefore the light colour (or colour temperature to give it its true term) will remain constant.

    Personally I have a multi-level lighting scheme implemented using different fittings and technologies. Bright warm white LEDs on the ceiling for when I need lots of light (with LED 16 watts instead of 200 watts). Standard halogen incandescent’s in table lamps on 100% for general lighting (48 watts) and when I want to really kick back, I set the table lamps down to 25% (12 watts) and switch on my electric ‘feature’ fireplace (currently with standard incandescent lamps @ 160 watts – ouch). Each of these moods are controlled by a LightwaveRF mood switch (even the fireplace).

    The point here is that the driver for me is to reduce energy. I want the remote control offered by LightwaveRF (actually more than the dimming capability per se), but because of the way the RF works, I need dimmable lamps. Halogen lamps will always be dimmable and work well, but they are expensive to run especially when you want lots of light output. LEDs and Compact Florescent’s are cheap to run, but difficult to dim and don’t have the same dimming curve as halogens. The LED Hut dimmable LEDs work as well as can be expected with LightwaveRF dimmers and that is the reason I recommend them. LEDs are not yet a true replacement for halogen and may never be so, but they are cheaper to run and they work and with that in mind, I’m content to forgive their nuances.

    The 20% off offer has been extended to the end of June. In addition, I have had an e-mail today announcing a flash sale on the 4W wide angle LEDs (http://lightwaverfcommunity.org.uk/shop/compatible-lamps/4-watt-gu10-led-bulb-wide-beam-angle-50-watt-replacement/) – they are now just £5.57 each for the dimmable ones (when used with the 20% off code above – LEDRF20)

    If you like these (personally I now prefer the newer 5W ones) get them while they are hot (and cheap!)

    Looks like the flash sale on the 4W LEDs at LED Hut ends at midnight tonight.
