Banyak sekali pengemudi mobil yang telah melengkapi mobil Toyotanya dengan lampu HID agar lebih terang maupun enak dipandang mata karena sorot cahayanya yang berwarna putih. Dan masih banyak juga yang masih binggung ataupun bimbang di dalam memilih HID yang tepat untuk mobilnya. Kali ini, kita akan membahas lebih dalam tentang bohlam HID beserta kelebihan dan kekurangan lampu HID itu sendiri agar tidak terjebak maupun ragu-ragu ketika memutuskan untuk menggunakan bohlam HID sebagai pilihan utama untuk penyinaran mobilnya.
Pengertian Lampu HID
HID sendiri telah memiliki kepanjangan, yaitu High Intensity Discharge atau yang lebih dikenal dengan lampu Xenon yang mampu untuk menghasilkan cahaya dengan tingkat intensitas yang tinggi alias lebih terang. Untuk tingkat keterangan warna dari lampu HID ditentukan oleh satuan derajat Kelvin (K) dan untuk menyalakan lampu HID diperlukan ballast, yang juga merupakan alat untuk menyediakan dan mengendalikan voltase lampu termasuk juga untuk dapat menstabilkan aliran listrik pada mobil.
Saat ini, sudah sangat banyak sekali lampu HID dengan berbagai merk atau tipe dengan kualitas yang berbeda-beda, produksi dan tentu saja berbeda harga. Karena banyak merk dan kualitas serta janji-janji yang telah ditawarkan, kita juga harus jeli di dalam memilih lampu HID untuk diaplikasikan pada kendaraan kita.
Untuk jenis atau tipe lampu HID yang beredar dipasaran, umumnya telah terdiri dari lampu-lampu model H1,H3,H4,H7,H8,H11,HB3,HB4. Yang telah membedakan antara kode H tersebut adalah pada kedudukan bohlamnya di headlamp mobil kita, sedangkan untuk ballast dapat dikatakan sama semuanya bentuknya (Ingat, sama bentuk belum tentu sama kualitasnya) Model yang paling umum beredar di Indonesia adalah tipe H4 dimana antara lampu jauh dengan lampu dekat menjadi satu.
Warna Cahaya Lampu HID
Lampu HID telah memiliki beberapa tingkatan warna yang dihasilkan berdasarkan perbedaan Kelvin, dan berikut ini adalah daftar warna Lampu HID yang terdapat di pasaran :
3.500 K mengeluarkan warna Kuning seperti bohlam lampu standart mobil
4.300 K / 5.000 K mengeluarkan warna putih kekuning-kuning an
6.000 K / 6.500 K mengeluarkan warna Putih
8.000 K/ 8.500 K mengeluarkan warna Putih kebiru-biru an
10.000 K mengeluarkan warna Biru agak keungu-ungu an
12.700 K mengeluarkan warna Ungu
15.000 K mengeluarkan warna Pink

Dari daftar warna di atas, kita juga dapat mengetahui bahwa semakin tinggi Kelvin maka akan mengalami gradasi warna menuju kebiru-biruan ataupun ungu. Hal yang paling penting untuk diingat adalah ketika pemasangan lampu HID selalu pastikan bahwa lampu yang terpasang adalah dengan ukuran 35 watt, jangan memasang yang 50 watt (tidak compatible) karena akan membuat mika head lamp menjadi cepat kuning akibat panas yang berlebihan.
Kelebihan dan Kelemahan lampu HID
Apabila membahas penggunaan lampu HID, maka kelebihan yang telah ditawarkan dari lampu ini (menurut saya) adalah gaya. Tentu sangat enak dilihat ketika melihat cahaya lampu putih yang keluar dari head lamp mobil TETAPI hal ini seringkali menyengsarakan saya sebagai pengemudi ketika di depan mobil yang menggunakan lampu HID.
Pilihan yang paling tepat di dalam menggunakan lampu HID adalah yang 4.300 K, dimana Toyota Fortuner, Alphard maupun mobil premium Toyota lainnya juga sudah menggunakan lampu HID sebagai standart bawaan mobil. Dan batas tolerir yang masih saya anggap menguntungkan adalah pemakaian lampu HID 5.000 / 5.300 K, dimana cahaya yang dikeluarkan masih putih kekuning-kuningan.
Kelemahan lampu HID juga sangat terlihat untuk lampu HID diatas 5.300 Kelvin tentu saja lampu HID yang dipasang lebih diperuntukan untuk mobil-mobil show off ataupun pameran karena cahaya lampu yang dihasilkan tidak dapat menembus hujan maupun kabut. Hal ini tentu saja telah menyusahkan pengemudi yang memiliki mobilitas tinggi di luar-luar daerah. Dari segi fungsional, lampu-lampu HID yang berada di atas 5.300 K seringkali membuat pengemudi mengeluhkan bahwa sorot cahaya lampunya sama sekali tidak membantu di tengah malam berkabut ataupun hujan sekalipun, dan hal ini juga sangat membahayakan kita sebagai pengendara mobil.
Pertanyaan yang paling sering diajukan kepada saya adalah, " Merk apa yang bagus untuk lampu HID ?"
Jujur, penilaian yang bisa saya berikan tentu saja, "ada harga tentu ada kualitas."Setelah mencoba-coba berbagai macam HID dan mencari fakta tentang lampu HID yang beredar di pasaran, ternyata hampir sebagian besar HID adalah produk China dengan embel-embel lisensi negara-negara maju seperti german, usa, dll.
Yang telah membedakan produk mahal dan murah adalah kualitas ballast dan kualitas bohlam lampu HID itu sendiri. Produk yang terlampau murah seringkali ballast cepat mengalami kerusakan sehingga lampu HID mati dalam waktu dekat, memang semua HID rata-rata telah memberikan garansi tetapi bila mengalami mati lampu di malam hari dan harus bolak balik untuk klaim pemasangan, bukankah itu merepotkan ? Kualitas bohlam juga mempengaruhi karena seringkali lampu HID berubah derajat Kelvin nya setelah pemakaian dalam beberapa bulan sehingga cahaya yang dikeluarkan oleh lampu HID menjadi tidak sama dengan pemasangan pertama kali.
Setelah membahas kelemahan dan kelebihan lampu HID, semoga teman-teman sekalian tidak merasa kebinggungan di dalam menentukan apakah perlu menggunakan HID atau tidak, dan lampu HID apa yang sebaiknya digunakan di mobil toyota kesayangannya. Sebenarnya pemasangan aksesoris pada mobil baru yang kita miliki menyebabkan beberapa kekurangan yang mungkin saja dapat berakibat fatal. (baca : kekurangan aksesoris mobil baru)
KELEBIHAN DAN KEKURANGAN LAMPU HID
Even as a high school student, Dave Goldberg was urging female classmates to speak up. As a young dot-com executive, he had one girlfriend after another, but fell hard for a driven friend named Sheryl Sandberg, pining after her for years. After they wed, Mr. Goldberg pushed her to negotiate hard for high compensation and arranged his schedule so that he could be home with their children when she was traveling for work.
Mr. Goldberg, who died unexpectedly on Friday, was a genial, 47-year-old Silicon Valley entrepreneur who built his latest company, SurveyMonkey, from a modest enterprise to one recently valued by investors at $2 billion. But he was also perhaps the signature male feminist of his era: the first major chief executive in memory to spur his wife to become as successful in business as he was, and an essential figure in “Lean In,” Ms. Sandberg’s blockbuster guide to female achievement.
Over the weekend, even strangers were shocked at his death, both because of his relatively young age and because they knew of him as the living, breathing, car-pooling center of a new philosophy of two-career marriage.
“They were very much the role models for what this next generation wants to grapple with,” said Debora L. Spar, the president of Barnard College. In a 2011 commencement speech there, Ms. Sandberg told the graduates that whom they married would be their most important career decision.
In the play “The Heidi Chronicles,” revived on Broadway this spring, a male character who is the founder of a media company says that “I don’t want to come home to an A-plus,” explaining that his ambitions require him to marry an unthreatening helpmeet. Mr. Goldberg grew up to hold the opposite view, starting with his upbringing in progressive Minneapolis circles where “there was woman power in every aspect of our lives,” Jeffrey Dachis, a childhood friend, said in an interview.
The Goldberg parents read “The Feminine Mystique” together — in fact, Mr. Goldberg’s father introduced it to his wife, according to Ms. Sandberg’s book. In 1976, Paula Goldberg helped found a nonprofit to aid children with disabilities. Her husband, Mel, a law professor who taught at night, made the family breakfast at home.
Later, when Dave Goldberg was in high school and his prom date, Jill Chessen, stayed silent in a politics class, he chastised her afterward. He said, “You need to speak up,” Ms. Chessen recalled in an interview. “They need to hear your voice.”
Years later, when Karin Gilford, an early employee at Launch Media, Mr. Goldberg’s digital music company, became a mother, he knew exactly what to do. He kept giving her challenging assignments, she recalled, but also let her work from home one day a week. After Yahoo acquired Launch, Mr. Goldberg became known for distributing roses to all the women in the office on Valentine’s Day.
Ms. Sandberg, who often describes herself as bossy-in-a-good-way, enchanted him when they became friendly in the mid-1990s. He “was smitten with her,” Ms. Chessen remembered. Ms. Sandberg was dating someone else, but Mr. Goldberg still hung around, even helping her and her then-boyfriend move, recalled Bob Roback, a friend and co-founder of Launch. When they finally married in 2004, friends remember thinking how similar the two were, and that the qualities that might have made Ms. Sandberg intimidating to some men drew Mr. Goldberg to her even more.
Over the next decade, Mr. Goldberg and Ms. Sandberg pioneered new ways of capturing information online, had a son and then a daughter, became immensely wealthy, and hashed out their who-does-what-in-this-marriage issues. Mr. Goldberg’s commute from the Bay Area to Los Angeles became a strain, so he relocated, later joking that he “lost the coin flip” of where they would live. He paid the bills, she planned the birthday parties, and both often left their offices at 5:30 so they could eat dinner with their children before resuming work afterward.
Friends in Silicon Valley say they were careful to conduct their careers separately, politely refusing when outsiders would ask one about the other’s work: Ms. Sandberg’s role building Facebook into an information and advertising powerhouse, and Mr. Goldberg at SurveyMonkey, which made polling faster and cheaper. But privately, their work was intertwined. He often began statements to his team with the phrase “Well, Sheryl said” sharing her business advice. He counseled her, too, starting with her salary negotiations with Mark Zuckerberg.
“I wanted Mark to really feel he stretched to get Sheryl, because she was worth it,” Mr. Goldberg explained in a 2013 “60 Minutes” interview, his Minnesota accent and his smile intact as he offered a rare peek of the intersection of marriage and money at the top of corporate life.
While his wife grew increasingly outspoken about women’s advancement, Mr. Goldberg quietly advised the men in the office on family and partnership matters, an associate said. Six out of 16 members of SurveyMonkey’s management team are female, an almost unheard-of ratio among Silicon Valley “unicorns,” or companies valued at over $1 billion.
When Mellody Hobson, a friend and finance executive, wrote a chapter of “Lean In” about women of color for the college edition of the book, Mr. Goldberg gave her feedback on the draft, a clue to his deep involvement. He joked with Ms. Hobson that she was too long-winded, like Ms. Sandberg, but aside from that, he said he loved the chapter, she said in an interview.
By then, Mr. Goldberg was a figure of fascination who inspired a “where can I get one of those?” reaction among many of the women who had read the best seller “Lean In.” Some lamented that Ms. Sandberg’s advice hinged too much on marrying a Dave Goldberg, who was humble enough to plan around his wife, attentive enough to worry about which shoes his young daughter would wear, and rich enough to help pay for the help that made the family’s balancing act manageable.
Now that he is gone, and Ms. Sandberg goes from being half of a celebrated partnership to perhaps the business world’s most prominent single mother, the pages of “Lean In” carry a new sting of loss.
“We are never at 50-50 at any given moment — perfect equality is hard to define or sustain — but we allow the pendulum to swing back and forth between us,” she wrote in 2013, adding that they were looking forward to raising teenagers together.
“Fortunately, I have Dave to figure it out with me,” she wrote.
