LED Bulbs Made in Mumbai: Our 9W to 50W Range

What we make: LED lamps from 9W to 50W

We are an LED bulb manufacturer in Mumbai, and our VIYONA pc. series covers the whole run of household and commercial LED lamps: a 0.5W night lamp, standard lamps of 9W, 12W, 15W, 18W and 23W, and the big Sumo lamps of 30W, 40W and 50W. Every one has a B22 bayonet cap, the push-and-twist cap that fits the batten and pendant holders in most Indian homes.

Our printed catalogue lists each lamp by code, wattage and MRP, from ₹40 for the night lamp to ₹720 for the 50W Sumo, packed ten to a box. This page is the overview for buyers and dealers: what the range is, what is inside a lamp, how the standard is marked, and which wattage to read about next. The individual wattage pages go deeper on rooms, units and price.

We started in 1995 with switches and sockets, and LED lighting grew out of the same works and the same dealer network: the shop that stocks our switch boards can order our lamps in the same delivery. That is also why our LED lamps carry printed MRPs code by code, like the rest of our catalogue.

Inside an LED lamp, and our four lamp shapes

Drawn by us, not to scale. The driver inside the body converts mains AC to the low-voltage DC the LED chips need; the B22 cap is the same on every lamp in the range.

Our LED lamp range and MRPs

The lamp section of our catalogue has nine codes. These are the printed MRPs, each for one lamp:

The cheapest working lamp is the 9W 1065: ₹70, and the one a home needs most of. The price climbs faster than the watts above it: 12W: ₹145, 15W: ₹212, 23W: ₹410. The Sumo 30W: ₹480 starts the high-wattage group.

Inside the lamp: why the driver matters

An LED lamp is not a filament in a glass bulb. It has four parts: a diffuser dome that spreads the light, a board of LED chips, a driver in the neck that turns 230 V AC into low-voltage DC, and the B22 cap with its two side pins.

The chips last a long time if they stay cool. The driver is the part that usually gives up first, and heat is what kills it: a lamp boxed into a closed glass shade, or run on a dimmer it was not built for, runs hotter than one hanging in open air. Our guide on why an LED bulb fuses quickly goes through voltage, heat and loose holders one by one, and the LED driver guide explains what the driver does.

Which wattage for which room

Each wattage has its own job. In short:

• 9W for bathrooms, passages, balconies, the pooja shelf and stores: see our 9 watt LED bulb guide.
• 12W as the single main light in a 10 × 10 ft or 10 × 12 ft bedroom: see the 12 watt LED bulb guide.
• 15W for kitchens and larger bedrooms: see the 15 watt LED bulb guide.
• 18W and 23W for living rooms and small shops.
• Sumo 30W to 50W for shops, godowns and high ceilings: see the 30 watt LED bulb guide.

Watts tell you the electricity a lamp draws, not how bright it is. Our catalogue lists watts and MRP but no lumen figures, so read the lumens printed on the carton; our lumens vs watts guide explains how to compare two lamps. To count fittings for a whole room, use how many lights in a room.

Standard lamp or Sumo?

Our 9W to 18W lamps have the familiar round globe. The 23W (1069) and the Sumo 30W, 40W, 50W have a tall, cylindrical body, wider and longer than a household lamp, because more watts need more surface to shed heat.

That shape changes where they fit. A Sumo will not go inside most decorative shades or small pendant fittings, and it is heavier on the holder. It belongs in an open batten holder on a ceiling high enough that its light can spread, which in practice means shops, godowns, workshops, garages and tall porches rather than flats with 9 ft ceilings.

Both shapes use the same B22 cap, so the holder you already have will take either, provided it is sound and its terminals are tight. Our B22 vs E27 guide shows how to tell which holder you have, and the batten holder guide covers our holders.

The standard and registration on our lamps

Our catalogue prints the Indian standard and the registration beside the lamp list: IS 16102 (Part 1): 2012 and registration R-71026514, with the model range printed as VE-STARS LAMP 3W–30W and the note that the lamps use BIS-approved control gear.

IS 16102 Part 1 is the Indian safety standard for self-ballasted LED lamps, the kind with the driver built into the lamp. The registration number is the one a buyer can look up on the BIS website. Note what the printed range covers: lamps from 3W to 30W. Our IS codes guide lists the standards for every product we make and explains how registration differs from an ISI mark.

What a box costs: figures for dealers

Every lamp code is packed 10 per box and sold in full boxes only. At MRP, a box comes to:

A counter serving homes needs the 9W and 12W most; one serving shops, workshops and godowns needs the Sumo. Our dealer margins guide explains how MRP, dealer price and margin relate, and the full LED light price list covers every LED code we make.

Running cost: units by wattage

Units on the bill are watts × hours ÷ 1,000. At 6 hours a day for 30 days, one lamp of each wattage uses:

• 9W: 1.6 units a month
• 12W: 2.2 units a month
• 15W: 2.7 units a month
• 23W: 4.1 units a month
• Sumo 30W: 5.4 units a month

An old 60W filament bulb on the same hours used 10.8 units, so the 9W does the same everyday job for about a sixth of the electricity. The wattage pages work these sums at the hours each lamp is really used, and our electricity bill guide turns units into rupees on your own tariff.

Changing a whole flat over to LED

A home rarely needs just one lamp. More often a whole flat changes over at once, when the family moves in or the old CFLs start failing one after another. A typical 2BHK with tube fittings in the main rooms still has lamp holders in the bathrooms, passage, balcony, kitchen and bedrooms. A sensible lamp list for such a flat looks like this:

• 4 × 9W (1065) for two bathrooms, the passage and the balcony: ₹280
• 3 × 12W (1066) for the two bedrooms and the pooja or study corner: ₹435
• 2 × 15W (1067) for the kitchen and the living room holder: ₹424

That is nine lamps for ₹1,139 at MRP, drawing 102W if every one is on at once. The same nine points with old 60W and 100W filament bulbs would have drawn several times that. Keep one spare 9W in the drawer: it is the lamp that fits the most places in the house.

Before you buy, look up at every holder and note which ones sit inside a closed shade or a small decorative fitting. Those need the compact round lamps, not the tall 23W or Sumo. Our electrical accessories list for a new home covers the rest of the shopping list.

Other LED lights we make

Lamps are one part of our LED catalogue. The same VIYONA range includes:
