Description
50 years old torch search light restoration. Lithium iron battery. Sanyo NL1000 light torch repair with minimal tools and materials. This Sanyo NL1000 model torch or search light is iconic item from Japan. They were very expensive those day. A poor or average man can't even afford them. I got one for very low price and restore it by replacing its rechargeable batteries with new and also added a four diodes bridge rectifier for better charging. These Sanyo torches were having only single diode half wave rectifier for charging such small Nickle Cadmium batteries those days. Maybe diodes were expensive or they didn't bother to fix a bridge rectifier for better charging efficiency in such torches or search lights. Latter in 90s Sanyo stopped this model production and they start producing high power models. This torch don't have an LED for light source. Instead they use 2.4V halogen light bulb which produces a beautiful and stable golden light.
The history of Sanyo torches is part of the larger history of the Japanese electronics manufacturer Sanyo Electric Co., Ltd., which was acquired by Panasonic in 2012. Sanyo produced various consumer electronic items, including dry batteries and flashlights, which were notably popular in the 1990s and often used for their reliability and rechargeable capabilities.
Key aspects of the Sanyo torch history:
Company Background: Sanyo Electric was founded by Toshio Iue in 1947 in Osaka, Japan. The company initially focused on sales of celluloid products but quickly expanded into manufacturing consumer electronics like televisions, washing machines, and refrigerators.
Product Popularity: Certain models of Sanyo torches, such as those in the "Cadnica" or "Ni-Cd" (Nickel-Cadmium) and later "Ni-MH" (Nickel-Metal Hydride) rechargeable lines, gained a reputation for being durable and long-lasting. They were particularly popular in regions like the UK, Bangladesh, Pakistan, and India, where travelers often carried them as personal items or gifts.
"Police Torch" Nickname: Due to their robust build quality and reliability, they were commonly used by police in some areas (like Bangladesh) and earned the informal nickname "police torch".
Rechargeable Technology: Sanyo was a pioneer in rechargeable battery technology, a core component of their popular torches. This legacy continued through their development of the highly regarded Eneloop rechargeable batteries, a brand now owned by Panasonic.
Acquisition and Brand Shift: As Sanyo faced financial difficulties, it was gradually acquired by Panasonic, with the deal completed in 2012. The Sanyo brand largely faded from the consumer electronics market, and existing products became vintage or collector's items. The Sanyo company name still exists for other specific product lines like Sanyo Chemical or Sanyo Shokai (clothing), but not for general consumer flashlights.
Today, vintage Sanyo torches are often found in online marketplaces or antique forums, where users discuss their history and durability.
