LED bulbs: how to choose the right cap and brightness
Choose the kind of LED bulb you need and match the cap to your light. Then pick brightness and light colour. Range numbers are from 12 November 2026: 95 bulbs, with 86 added in the last year.
Which kind of LED bulb should I buy?
Choose an everyday, candle, filament, spot, high-watt or special bulb according to the fitting and its use.
- Everyday round: a familiar bulb shape for regular lighting at home or in a shop.
- Candle: a slim, pointed shape for chandeliers and small lamps.
- Filament: visible glowing lines for open hanging lights and lamps where the bulb shows.
- Spot: GU10 and MR16 bulbs for downlights and spotlights; check the cap before ordering.
- High-watt: bulbs for large rooms, shops and sheds; confirm that the fitting can take the selected bulb.
- Special: bulbs for a particular job or decorative look, rather than a routine replacement.
Our 12 special bulbs include rechargeable emergency and solar bulbs, tilting-wing bulbs for large spaces, and decorative filament shapes. These include heart-shaped and large decorative bulbs. Check each product page for its operation and ratings.
Choose the bulb's look before its light colour. For a visible bulb, compare candle, round and tubular shapes with your shade. The hanging light guide helps with open fittings. Browse the LED bulb collection to compare current options.
How do I choose the right bulb cap?
Match the cap on your old bulb, or the cap named on your light's product page.
- B22: push-and-twist with side pins, common in Indian homes.
- E27: the standard screw cap; E14: the smaller screw cap used in candle bulbs and small lamps.
- GU10: a twist-in pin cap for mains spotlights; MR16: a pin cap for low-voltage spot bulbs.
- G9: small loop pins for decorative fittings; G4: tiny pins for small bulbs.
- E40: a large screw cap for high-watt bulbs.
B22 is the most common listed cap in our range, followed by E27 and products offering cap choices. GU10, MR16, G9, G4, G24, E40 and QR111 are smaller groups. Where several caps are listed, select the variant your fitting needs.
Check bulb length, width and space inside the shade as well as the cap. Size options vary, check the product page. Send a photo of the old bulb and holder if the cap is unclear.
How many watts should my LED bulb be?
For an old bulb replacement, about 7 to 9 W LED is a starting point for an old 60 W bulb.
About 13 to 15 W LED is a starting point for an old 100 W bulb. These are approximate comparisons, not a room lighting plan. For LED replacements, compare the stated light output, called lumens, as well as watts.
Our range has 81 bulbs with a stated wattage:
- Up to 5 W: 25 bulbs.
- 5 to 10 W: 37 bulbs.
- 10 to 20 W: 11 bulbs.
- Over 20 W: 8 bulbs.
Most product pages list light output. Do not choose a decorative bulb on shape alone when it must also light your room.
Should I choose warm white or cool white?
Warm white is a good starting point for living spaces; neutral or cool white suits different work areas.
Most of our bulbs come in warm white or cool white, and a few in neutral white.
- Warm white: about 2700K to 3000K is a starting point for living rooms, bedrooms and dining areas.
- Neutral white: about 4000K is a starting point for kitchens, studies, bathrooms and offices.
- Cool white: about 5000K to 6000K is a starting point for utility rooms, work areas and shops wanting bright white light.
Warm light is also a suggestion for paintings, wood and brass finishes. Choose the colour option on the product page. A single colour-switch bulb changes between warm, neutral and cool when switched off and on at the wall.
Can I use any LED bulb with a dimmer?
Use only a bulb marked dimmable, with a dimmer that suits LED bulbs.
A bulb without that marking may not work well on a dimmer. Our dimmable choice is small: look for candle, filament and round bulbs explicitly marked dimmable. A filament look alone does not confirm dimming.
Check the exact variant before buying from the dimmable bulb collection. Tell our team which dimmer you already have. Warranty depends on the model.
Can these bulbs go in indoor and outdoor fittings?
Use the bulb in a matching fitting, and check the outdoor fitting's own IP rating for its location.
Almost all listed bulb IP ratings are IP20, which is for dry indoor places only. The bulb's cap or shape does not confirm suitability outdoors. Read the bulb and fitting product pages together.
MR16 bulbs run on 12V, and G4 bulbs usually do too. A 12V bulb needs a matching driver of the same voltage. Check the label before replacement and see the driver and controls guide.
How much does an LED bulb cost in India?
Our median LED bulb price was about ₹160 on 12 November 2026.
These bands cover 94 priced products, using each product's lowest variant price, including GST.
One product has price on request. Compare the cap, light colour and dimming option before comparing prices. The product page shows the current price.
What should I check before buying an LED bulb?
Confirm the bulb kind, cap, physical fit, brightness, light colour and dimming before ordering.
- Choose everyday, candle, filament, spot, high-watt or special.
- Match the old bulb's cap and check the selected variant.
- Check length and width against the fitting and shade.
- Compare watts and the stated light output.
- Choose warm, neutral or cool white for the room.
- For dimming, confirm both bulb and dimmer compatibility.
- For low-voltage bulbs, confirm the matching driver.
- For outdoor use, check the fitting's own IP rating.
- Read the current price and model's warranty details.
Questions and answers
The right replacement starts with the fitting's cap and the bulb's stated features.
What is the difference between a B22 LED bulb and an E27 LED bulb?
B22 pushes and twists into its holder; E27 screws in. Choose the cap your holder accepts.
Is a filament bulb the same as an Edison or vintage bulb?
These names describe the visible glowing-line look. Compare the actual shape and cap, then check whether dimming is stated.
Which decorative bulb suits a table lamp?
Consider candle or filament shapes when the bulb shows. Check shade clearance with the table and floor lamp guide.
Can a G9 LED bulb replace a GU10 LED bulb?
They use different caps: G9 has loop pins, while GU10 has twist-in pins. Match the original cap.
Do you have a day night sensor bulb?
There is a single model: a motion-sensor bulb with a day and night feature. It responds to movement and stays off in daylight. Check the sensor bulb product details before ordering.
How do I check the price of a replacement LED bulb?
Open the product page and select the required cap and light colour. Check dimming and warranty details for that model.
Can I get a warm decorative bulb for a B22 holder?
Options vary, so check that the selected decorative bulb variant lists both B22 and warm white. Also check its length and width against the shade. If that combination is not listed, ask our team to confirm availability before ordering.
