Tips Memilih Lampu Mobil HID. Saat mengemudi seringkali telah menghadapi berbagai macam ringantan, salah satunya adalah kemacetan lalu lintas, anda juga dapat membayangkan jika anda mengemudi di malam hari, di jalanan yang sepi, tiba-tiba mendadak lampu depan mobil mati, sehingga pandangan ke depan menjadi gelap.

Hal tersebut dapat terjadi ketika lampu halogen, yang umumnya telah digunakan pada mobil saat ini dan biasanya untuk jangka waktu tertentu mudah cepat rusak. Tetapi jangan khawatir, karena solusinya adalah anda dapat menggunakan tipe bohlam HID yang telah mempunyai umur lebih panjang.

Anda dapat melupakan Halogen, dan beralih ke HID

Dengan lampu mobil konvensional yang menggunakan halogen sebagai sumber cahaya, maka lampu HID juga sudah memanfaatkan gas xenon bersama dengan garam logam halide dan merkuri. Komponen tersebut juga dapat membentuk suatu lengkungan arus tegangan tinggi yang bersatu menyebabkan cahaya sinar cerah, mirip dengan lampu neon. Karena penggunaan gas xenon di dalam lampu, sehingga sering disebut dengan lampu depan xenon

Bagaimana cara kerjanya?

Bila anda sudah mengaktifkan lampu mobil baru 2014 anda, maka tegangan tinggi 12V didistribusikan sepanjang kumparan relay, akibatnya kontak ditutup, dari titik tersebut maka tegangan 12V digunakan untuk dapat menghidupkan pemberat di dalam lampu xenon. Pemberat inilah yang kemudian akan menyala dan memberikan tenaga listrik untuk lampu.

Mengapa HID Itu diperlukan?

Jika dibandingkan dengan lampu mobil konvensional, maka lampu HID telah mempunyai cukup banyak keuntungan, dengan lampu HID yang biasanya tiga kali lebih terang daripada yang konvensional. Plus juga dapat memberikan jarak penglihatan jalan di depan lebih besar sampai dengan 70%

Bagaimana memilihnya?

Bila anda berminat untuk menggantinya, ada beberapa hal yang perlu untuk dicermati. Anda juga harus cek ukuran bola lampu sebelumnya, kebanyakan bola lampu yang terdapat adalah uuran H1, H3, H4, H7, selanjutnya setelah menentukan warna temperatur yang diinginkan, anda juga dapat menentukan suhu yang dapat diukur dalam satuan K atau derajat Kelvin. Hal ini untuk dapat menentukan warna apa lampu HID akan memuaskan.

Apakah ada kemungkinan masalah ?

Jika anda mencoba hal baru, pasti terdapat kelemahan dan kelebihannya. Karena itu sifat pencahayaan HID begitu terang dan cerah, terutama di malam hari karena kontras. Oleh karena itu sinar lampu yang terpancar dari mobil tersebut dapat membuat silau pengemudi dari arah berlawanan.

Perawatan dan Pemeliharaan.

Agar umur pakai HID awet dan bertahan lama, sebaiknya anda tidak berusaha untuk dapat mematikannya sesaat setelah dihidupkan. Lampu jenis ini biasanya memerlukan waktu 60 detik untuk pemanasan sebelum dapat beroperasi secara normal. Sebab itu, jangan mencoba untuk memainkannya, karena kemungkinan rusak akan lebih cepat.

Anda juga dapat melakukan cek beterai jika mobil sudah lama tidak digunakan. Jika tidak rajin dicek maka akan membuat baterai tersebut kadaluarsa , dan anda sudah tidak dapat menggunakannya. Tetapi anda tidak perlu khawatir sebab baterry jenis NimH mampu bertahan lama



Imagine an elite professional services firm with a high-performing, workaholic culture. Everyone is expected to turn on a dime to serve a client, travel at a moment’s notice, and be available pretty much every evening and weekend. It can make for a grueling work life, but at the highest levels of accounting, law, investment banking and consulting firms, it is just the way things are.

Except for one dirty little secret: Some of the people ostensibly turning in those 80- or 90-hour workweeks, particularly men, may just be faking it.

Many of them were, at least, at one elite consulting firm studied by Erin Reid, a professor at Boston University’s Questrom School of Business. It’s impossible to know if what she learned at that unidentified consulting firm applies across the world of work more broadly. But her research, published in the academic journal Organization Science, offers a way to understand how the professional world differs between men and women, and some of the ways a hard-charging culture that emphasizes long hours above all can make some companies worse off.

Ms. Reid interviewed more than 100 people in the American offices of a global consulting firm and had access to performance reviews and internal human resources documents. At the firm there was a strong culture around long hours and responding to clients promptly.

“When the client needs me to be somewhere, I just have to be there,” said one of the consultants Ms. Reid interviewed. “And if you can’t be there, it’s probably because you’ve got another client meeting at the same time. You know it’s tough to say I can’t be there because my son had a Cub Scout meeting.”

Some people fully embraced this culture and put in the long hours, and they tended to be top performers. Others openly pushed back against it, insisting upon lighter and more flexible work hours, or less travel; they were punished in their performance reviews.

The third group is most interesting. Some 31 percent of the men and 11 percent of the women whose records Ms. Reid examined managed to achieve the benefits of a more moderate work schedule without explicitly asking for it.

They made an effort to line up clients who were local, reducing the need for travel. When they skipped work to spend time with their children or spouse, they didn’t call attention to it. One team on which several members had small children agreed among themselves to cover for one another so that everyone could have more flexible hours.

A male junior manager described working to have repeat consulting engagements with a company near enough to his home that he could take care of it with day trips. “I try to head out by 5, get home at 5:30, have dinner, play with my daughter,” he said, adding that he generally kept weekend work down to two hours of catching up on email.

Despite the limited hours, he said: “I know what clients are expecting. So I deliver above that.” He received a high performance review and a promotion.

What is fascinating about the firm Ms. Reid studied is that these people, who in her terminology were “passing” as workaholics, received performance reviews that were as strong as their hyper-ambitious colleagues. For people who were good at faking it, there was no real damage done by their lighter workloads.

It calls to mind the episode of “Seinfeld” in which George Costanza leaves his car in the parking lot at Yankee Stadium, where he works, and gets a promotion because his boss sees the car and thinks he is getting to work earlier and staying later than anyone else. (The strategy goes awry for him, and is not recommended for any aspiring partners in a consulting firm.)

A second finding is that women, particularly those with young children, were much more likely to request greater flexibility through more formal means, such as returning from maternity leave with an explicitly reduced schedule. Men who requested a paternity leave seemed to be punished come review time, and so may have felt more need to take time to spend with their families through those unofficial methods.

The result of this is easy to see: Those specifically requesting a lighter workload, who were disproportionately women, suffered in their performance reviews; those who took a lighter workload more discreetly didn’t suffer. The maxim of “ask forgiveness, not permission” seemed to apply.

It would be dangerous to extrapolate too much from a study at one firm, but Ms. Reid said in an interview that since publishing a summary of her research in Harvard Business Review she has heard from people in a variety of industries describing the same dynamic.

High-octane professional service firms are that way for a reason, and no one would doubt that insane hours and lots of travel can be necessary if you’re a lawyer on the verge of a big trial, an accountant right before tax day or an investment banker advising on a huge merger.

But the fact that the consultants who quietly lightened their workload did just as well in their performance reviews as those who were truly working 80 or more hours a week suggests that in normal times, heavy workloads may be more about signaling devotion to a firm than really being more productive. The person working 80 hours isn’t necessarily serving clients any better than the person working 50.

In other words, maybe the real problem isn’t men faking greater devotion to their jobs. Maybe it’s that too many companies reward the wrong things, favoring the illusion of extraordinary effort over actual productivity.
