Watts a Lumen ??

Ey up my faithful blogworms, What's (Watts) a Lumen ??

You may well ask ...... I thought it was worth following up on my COB lighting blog with an attempt to clear up some of the pure gooble-de-gook that's written on the side of light bulb boxes

You will see all sorts of rubbish written on the side of LED light bulb boxes, how the hell do you figure out which bulb it is that you need for your lights at home......

 1)  Right, lets start with Energy ratings, if you're looking at Gu10 bulbs in your ceiling like the ones shown in the pics, you're normally these days looking at LED's to save energy and money.
Fact: All LED lights save energy because they're low wattage, you've got to be a 'muppet' not to realise that 5 watts burns less energy than 50 watts !. So largely you can ignore the energy rating cos that's common to them all.

 2) Next: the wattage, this does not  tell you how bright they are, it used to with the old tungsten lights but it doesn't really help any more. The wattage simply tells you how much energy you will be using when you switch them on.
Believe it or not, a 4w, 4.5w, 5w, 6w, 7w & 8w can all give the same light output !! ..... "Give me a break!" I hear you say, how on earth can that be possible ?? I'll explain in a minute.

 3) Hours rating for bulb life:  generally a total bloody guess, if it says 50,000 hours on a bulb packet. 50,000 hours at 8 hours a day is 17.12 years, how the hell did they test that ?? The main factor, as I understand it that governs bulb life is heat ie: how hot a bulb gets while it's switched on.
The cooler the bulb runs, the longer it lasts and the less energy  you lose to heat. So then, 50,000 hours is no real judge of the reliability and longevity of a bulb. The only way to ensure you get a good lifespan on a bulb is to buy known and reputable brands, you buy cheap imports they will blow in no time at all and you've only got yourselves to blame for buying rubbish in the first place !! Remember: Buy cheap, buy twice, there's a reason they're cheap !! TIP: avoid Chinese writing on the box !

4) The next piece of info you get is something that says 2600K, 3000K, 4000K or whatever. This info can actually be useful in your bulb selection cos it tells you how warm or cool the light is. Generally 2800K to 3200K is accepted as a 'warm' white light and 4000K as a 'cool' white light. 
As a rule of thumb, the number gets smaller it gets warmer and higher it gets cooler. This can help you choose how the overall atmosphere in the room looks.

5) This is where we get to the really important bit ....... How much light am I going to get out of the bulb ??.
OK, this is where Lumens comes into it, Lumens are the amount of light output you get from any given bulb. Simply put, the higher the number, the more light you get out of it.

You will see in the pic, left, 110 Lumens ( poor output) the one above 160 Lumens ( better but still hopeless), the energy smart one at the top of the blog 200 Lumens ( getting better but you'd still need a lot of them in your ceiling to light a room up !!)

Now compare these to the COB lights I talked about previously where Cob light output is 400 Lumens for warm white and 430 Lumens for cool white and you really begin to realise that when you're looking for new bulbs to give a good light, change you're thinking and look for the Lumens rating. Nowadays you simply cannot rely on wattage figures like you used to !

If you've not read my blog about COB yet, then read "COB but no corn" from my list, a lot more of this weeks blog will make sense.

I hope this has helped you to re-think how you look at buying your bulbs and gone someway towards explaining what to look for and what to ignore on the box.

Your faithful servant, as ever. Jules

Webbed feet ??

Ey up my faithful blogworms, as the gales and storms continue to lash the UK this week, comments are being made by experts saying ....

 "OK people, climate change is a reality, when are you going to start believing ?" ... 

I know in a lot of cases with you, my followers, we're preaching to the converted but the message has to be driven forward cos if not, we'd all better start growing webbed feet or start investing in companies who manufacture waders. I've a feeling that the poor unfortunate people in the South and West of our wonderful country are probably starting already !

As you know from all my previous blogs, doing as much as we can to help stop the advance of climate change is what we, at Milestone, are all about. 

 Just as a reminder of the wide and varied ways we can help:

Cabinets: High recycled content MFC form the basis for all our eco kitchens, standard and bespoke.

Doors:& Accessories: Massive choice including; High recycled content MFC, Recycled plastics in Yoghurt Pot and Coffee Cup, Sustainable hardwoods in Oak, Ash & Walnut, Reclaimed Softwoods, Sustainable Tulipwood, Ecologically sound MDF, Organic paints to paint most of the above

All of them made bespoke to suit your kitchen ..... it's what we do best !!

Worktops: Sustainable Hardwoods, Recycled Yog Pot & Coffee Cup, Recycled / FSC mix Laminate worktops, Recycled Glass made from real bottles and now .... upto 40% Recycled content quartz ..... MORE ABOUT THESE NEXT WEEK !

Handles and shelf brackets hand forged from re-used steel

Recycled content, UK made floor and wall tiles for kitchens and bathrooms

Low energy lighting: now concentrating on the brand new 'COB' technology .... which, according to my blog stats,  appears to have really captured your interest last week !

And last but definitely not least: 'A' rated appliances in all shapes and sizes, functions and styles.

There are no excuses for not doing your bit by way of eco friendly kitchens, bedrooms and bathrooms, we've got it covered in a 'one stop shop' and I'll vouch there's nowhere else in the whole of the UK that can offer you this exceptional level of eco friendly products in one place, what are you waiting for ???

Think about it !  ....which is easier ..... spending wisely on an eco friendly project for your home .... or growing webbed feet ?

For those of you who don't take environmental damge seriously ... Wake up and smell the Roses, it's happening now !!

No brainer really 'innit.  Jules.

COB but without the corn !

Well, my faithful blogworms, this last week has been a voyage of discovery !!

 COB but no corn ! 
What on earth does that mean ?

I feel I need to open your eyes this week to a brand new form of low energy lighting ...... COB , this information needs to be shared, so tell all your friends to read this !!

COB is a totally new way of looking at LED lighting that finally breaks all the myths that low energy lighting is slow, costly and ineffective. It means: 'Chip On Board'. This technology combines many small chips integrated into one large chip and then bonded to a suitable substrate.

OK, that's the techie bit out of the way, what does it mean to me, well I'll tell you in simple terms !

In our terms it means that we now have very good light output lamps that are on at full brightness the second you switch them on. The two you see here, a GX53 under unit light ( the flat round one) and a GU10 ceiling downlight ( the other one ) are both only 5 watts and have a Lumens rating of 475 for the GX53 and 430 for the GU10. 

Importantly: these lights are perfect for retro fitting to your kitchen, in some cases, if you have GU10's in your ceilng at the moment  ..... all you need to do is change the bulbs, Simples !

TOP TIP:   When you're choosing an LED light of any form, look at the lumens rating, this is the amount of light you're actually getting out of the lamp and is every bit as important than the wattage. The higher the number, the better the light output. Check out a few in the shops and you'll see that the figures for the COB lights are very good indeed.

I've been directly involved with Led lighting for kitchens for some years now and I've tried some sample lights. 

WOW!! is all I have to say ! these are absolutely brilliant, the best I've ever seen.

Check out these benefits:

  • Higher light levels for lower wattages 
  • Lower wattage means cheaper bills
  • Instant light, no warm up time
  • A better spread of light from the lamp with a more uniform appearance
  • Lower cost than most LED lamps currently available
  • They are dimmable using most leading dimmers
  • They will work happily on home automation lights systems
  • Available in Warm & Cool white, the warm white is a good soft light not like some of the sickly yellow light that comes from other types
  • They run way cooler than normal LED lamps meaning a much longer lifespan with better stability

This should not be kept secret, I feel this is the most important development in LED lighting for a long time and it's going to take some beating, spread the word and get your friends buying:    
COB without the Corn !

Till next time, I'm relying on ya ! Jules.
