· They will cost you more in the beginningAnything good comes with a price, and anything better obviously comes with an increased price. Don't be fooled by the words cost-effective and reach the conclusion that LED bulbs are cheaper than regular ones. They cost more, but they are like an investment you make for future savings in electricity bill as well as a really long durability.
You will specifically see the difference if you are installing in large scale like LED High Bay Lights in your warehouse or LED floodlights outdoor.· Watts do not indicate brightness in LED bulbsSince the whole point of LED bulbs is that they draw less energy, the wattage of the bulb will not be very helpful in telling you its brightness quotient like its more traditional counterpart. The figure you need to look for while buying LED light bulbs in Australia is lumens.
For around 450 lumens brightness, an incandescent takes up as much as 40 watts, but an LED only uses 6-9 watts. The higher lumens a bulb provides per unit currency of its cost price, the more value for money you get.· LED lights do not fit in everywhereUsually LED lights can be installed in your normal fixtures, but keep an eye whether they are fully or partially enclosed.
The usual LED lights stay cool by sending off the heat into the air from its base, and if the fixture is covered, that will not be happening; thus significantly reducing your bulb's life. Install open fixtures or look for LED bulbs suited for enclosed ones to fix this.· Your old dimmers will not work with LEDsIf you like to regulate your home's lighting and had dimmers installed previously, chances are they will not work with the new LED bulbs.
So if you still want that feature, all you need to do is get dimmable LED lights. They are easily available in the shops.· Lifespan of the bulbBefore buying an LED bulb, do a quick math about its lifespan. They are usually given in hours in the package.
The commonly used bulbs for a home run for 50,000 hours, which means if you are using it for 10 hours per day, your bulb will be as durable as 13 long years. So get an idea of your daily usage before purchase.LED bulbs are very easy to shop for once you keep these small things in mind.
And the best part about them is, you do not need to worry about shopping again for a really long time

I didn't get Google Glass Explorer Edition. Is trying to learn Glass dev without the hardware a futile effort?
No, you can still learn the fundamentals of Glass development without the hardware.
There are three main approaches for accomplishing this:
1) Visit the Mirror API documentation, get into the playground, and start hashing up some code. Download the PHP, Java, and Python library, whichever you're most comfortable with. Familiarize yourself with the jargon and converntions (timeline, bundles, menus, etc). Read the support documentation (second link below) to see how the Glass hardware actually functions. Build some apps to this specification. Soon enough, you will find a friend with hardware to t
