Frequently asked questions
UV vs LED vs 2-in-1: which lamp tech should the salon stock?
Three lamp light technologies ship at ND. UV-only mercury bulb lamps cure legacy UV gel in 2 minutes (rare, only 2 SKUs at ND). LED-only single-wavelength lamps cure modern LED gel in 30 to 60 seconds but will not cure the older UV-only legacy gel. 2-in-1 UV plus LED hybrid lamps cure every gel system the salon stocks (Intelli-Gel, builder gel, cat eye, HEMA-free, dipping base) in 30 to 60 seconds. The 2-in-1 hybrid is the modern salon recommendation because one lamp covers the full gel inventory mix.
What wattage does the salon production-floor booth need?
72W to 96W is the salon production-floor standard. At that tier the lamp cures gel in 22 to 30 seconds, supports back-to-back service, and handles every modern LED gel including builder gel pull-through. 36W to 48W is the salon-starter tier for 1 to 3 clients per hour. 108W and up is for the builder gel extension salon needing sub-20-second cure on thicker layers.
Is the LAVIS 2-in-1 lamp the best value at ND?
The LAVIS 2in1 LED/UV lamp is the salon pick at ND because one plug-in lamp cures every gel system on the site, so the salon does not need a second lamp for legacy UV-only formulas, and it sits in the mid price tier between the value plug-in lamps and the premium cordless ones. The current Vol 2 ships in white, silver, pink, and gold for booth aesthetic match.
What's the wholesale ordering setup at ND?
No business license required, no minimum order, no membership fee. Free shipping on every order of $100 or more. Same-day dispatch on in-stock lamps ordered before 2pm PT weekdays. The lamp category bundles into gel collection orders at the volume-discount tier (10 to 25 percent off for orders of 30-plus units across any combination), which is the standard salon reorder cadence stocking lamps plus gel together.
How long does a salon LED lamp last?
LED-tier lamps at ND ship with high-MTBF LED arrays rated for 50,000-plus hours of cure time, which means the modern LED lamp at the salon production-floor wattage tier holds full bead output across years of daily service. UV-only legacy mercury-bulb lamps degrade 30 percent within 6 to 12 months and need a bulb swap at the 1-year service mark. The 2-in-1 hybrid uses LED beads for both wavelength outputs, so the maintenance schedule is the lower-touch LED schedule, not the mercury-bulb schedule.
Why the right lamp drives the salon's gel service tier
The nail lamp is the cure-side bottleneck of every gel service in the salon, which is why picking the right wattage, light tech, and timer firmware is the single hardware decision that controls service-time-per-client. ND Nails Supply stocks around 126 listings on this page, from the handheld portable for the at-home retail tier and the mini dust collectors that sit beside the lamp, to the rechargeable pro-tier table lamps with timers, multi-bead LED arrays, and motion-sensor activation for the upscale salon production floor. The hard rule is simple: an underpowered lamp under-cures the gel, the gel chips within a week, the client doesn't rebook. A correctly-spec'd lamp cures the same gel layer in 30 to 60 seconds and holds the service tier through the 21-day rebook window.
This page is the wholesale lamp catalog for ND clients picking the lamp tier for their booth setup, their salon menu, or their at-home brand line. The 2-in-1 UV plus LED hybrid dominates the modern salon floor because one lamp cures every gel system ND ships, Intelli-Gel, builder gel, cat eye, HEMA-free A'DOR, dipping base, and the salon doesn't need a second lamp for the older UV-only formulas still in some 2-in-1 customers' inventory.
UV vs LED vs 2-in-1: the technical comparison
Three lamp light technologies are currently shipping at ND. The choice depends on which gel systems the salon services and how fast the booth needs to turn a client. The bottom-line table:
| Lamp tech | Cure time per gel layer | Compatible gel | Notes |
|---|---|---|---|
| UV only (mercury bulb) | 2 minutes | Legacy UV gel only | Older formula, bulb degrades 6 to 12 months. Rare at ND, only 2 SKUs. |
| LED only (single-wavelength) | 30 to 60 seconds | Modern LED gel only | Faster than UV. Will NOT cure the older UV-only formula gel. Cure failure on mixed inventory. |
| 2-in-1 UV plus LED hybrid | 30 to 60 seconds | All gel: LED, legacy UV, builder, cat eye, HEMA-free | Dual-wavelength array. Single-lamp cures every gel system on the salon menu. Modern best-practice. |
The reason ND pushes the 2-in-1 hybrid as the default salon recommendation is simple: salons stocking multiple gel brands across multiple product lines (gel polish, builder gel, cat eye, chrome, HEMA-free) save the second-lamp purchase by going hybrid. The LAVIS 2-in-1 line at ND is the popular salon pick because the single lamp cures the full LAVIS gel family plus every third-party gel ND stocks.
Wattage explained: cure speed scales with wattage
Wattage is the second-most-asked spec at ND after light tech. Higher wattage equals more LED bead output per second, which equals faster cure on the same gel layer. The wattage-to-cure-speed relationship plots out linearly across the salon-tier range:
Wattage tier reading:
- 9W to 27W (handheld portable): travel lamp, retail sell-through, at-home top-up between salon visits. NOT the production-floor lamp.
- 36W to 48W (DIY home and salon starter): the entry-tier salon lamp. Cures every modern LED gel in 40 to 50 seconds. The booth lamp for new operators on a single client per hour.
- 72W to 96W (mid-salon and pro rechargeable): the production-floor standard. Cures gel in 22 to 30 seconds, supports back-to-back service. The recommended lamp for salons doing 4-plus gel services per chair per day.
- 108W and up (specialty 5X plus, high-throughput salon, builder gel): cures the thicker builder gel layer in under 20 seconds. Necessary for salons running builder gel extensions all day.
Top lamp tiers at ND with specs
The lamp listings at ND organize into four tiers plus accessories. The salon picks the tier that matches the booth's daily service volume:
| Tier | Wattage | Price tier | Best for | Models at ND |
|---|---|---|---|---|
| Handheld and mini | 12W to 27W | Entry | Travel, flash-curing a single nail, at-home retail sell-through | Portable Handheld LED, the LAVIS mini stand lamp, Flash Gel Cure 27W, the AI Sensor 12W portable |
| Salon starter | 36W to 108W plug-in | Value | New booth, single-chair, 1 to 3 clients per hour | LAVIS UV Desk Lamp, LAVIS Mini Desktop, Classy Nail Art UV/LED, the 48W lamps with a handle, Sun 5X Plus 108W and Super Sun X12 Max |
| Salon 2-in-1 (UV plus LED) | 48W to 96W | Mid | Daily salon production, mixed gel inventory | LAVIS 2in1 LED/UV Vol 2 (white, silver, pink, gold), LAVIS UV/LED, LDS UV/LED (six colors), CND LED, OPI Gel Lamp 3.0 |
| Pro rechargeable | 96W cordless | Premium | Mobile booth, multi-chair salon, no-cord ergonomics | Kiara Sky Beyond Pro V2 and V3, Apres Nova, Gelish 18 Light Unplugged, Kupa Manipro Glo, SNS cordless, the generic 96W cordless lamps |
| Accessories | Every station | Lamp shield plate, anti-blue-light goggles, and the mini dust collector that sits beside the lamp |
Margin signal: the LAVIS 2-in-1 line at ND is the highest-margin lamp option for the salon stocking gel + lamp combo because the bundle math works in a single order tier. The LDS multi-color line at ND ships in four salon-decor colors (black, pink, gray, yellow) for booth aesthetic match, and the LDS lamps sit alongside the LAVIS line at the salon-decor price tier.
Three lamps, three jobs
How to pick by service tier and booth volume
Match the lamp pick to the salon's dominant service load and the gel inventory mix:
- New operator, single chair, mixed-brand inventory: anchor on the LAVIS 2in1 LED/UV lamp. One lamp cures every gel system the salon stocks, including the older UV-only legacy gel still in some customer inventory.
- Mid-volume salon, 4 to 8 services per chair per day, gel polish heavy: pair the LAVIS 2-in-1 at the booth with a backup Kiara Sky Beyond Pro V2 rechargeable for the no-cord mobility on the second chair. Service-time drop to 22 seconds per layer cuts the gel-set step from 90 seconds to 60 seconds per finger.
- Builder gel extension salon, high throughput: the Sun 5X Plus 108W cures the thicker builder gel pull-through in under 20 seconds, which is the throughput requirement for back-to-back extension sets. Pair with the LAVIS 2-in-1 at the gel polish booth.
- Premium upscale salon, multi-chair, mobile booth: anchor on the Apres Nova rechargeable with the Kiara Sky Beyond Pro V3 as the second chair lamp. Both lamps are rechargeable, motion-sensor-activated, and ship with the premium upscale ergonomics the upscale client expects.
- At-home brand line, retail sell-through: the Portable Handheld LED is the retail price-point lamp for the at-home client topping up between salon visits.
Lamp application and safety workflow
The lamp cure step is the most safety-sensitive part of the gel service, both for the client's skin and for the technician's repetitive-strain ergonomics. Standard workflow:
- Skin prep: client's hand stays inside the lamp dome for the full cure time. Skin contact with curing UV/LED light is brief and safe at the salon-tier lamp's calibrated output but never bypass the timer for a faster cure.
- Eye protection: technician wears the UV-protective goggles when running 96W-plus lamp tier back-to-back. ND ships shield plates and goggles in the lamp accessory category.
- Glove or barrier: nitrile glove provides the routine barrier between the client's skin and any uncured gel residue. Reapply gel cleanly between layers, do not let residue accumulate at the cuticle.
- Timer use: use the lamp's calibrated timer (30s, 60s, 90s presets). Manual hold-button cure is allowed for thicker gel layers (builder gel pull-through) at the technician's discretion but always follow the gel manufacturer's recommended cure time.
- Lamp positioning: lamp sits 1 to 2 inches above the nail surface. Closer than 1 inch over-cures; further than 2 inches under-cures the side-edge of the nail.
Lamp maintenance and bulb life
LED-tier lamps at ND ship with high-MTBF (mean-time-between-failure) LED arrays rated for 50,000-plus hours of cure time, which means the modern LED lamp at the salon production-floor wattage tier holds the full bead output across years of daily service. UV-only legacy lamps with mercury bulbs degrade 30 percent within 6 to 12 months and need a bulb swap at the 1-year service mark. The hybrid 2-in-1 lamp at ND uses LED beads for both wavelength outputs, which means the maintenance schedule is the lower-touch LED schedule, not the mercury-bulb schedule.
Routine maintenance for the lamp at the salon booth:
- Weekly: wipe the inside dome with isopropyl alcohol on a lint-free wipe. Cured gel residue accumulates on the dome surface and lowers the bead-to-nail light path.
- Monthly: check the rubber base feet and timer button responsiveness. Replace the rubber base feet at the 12-month service mark.
- Quarterly: for rechargeable lamps (Kiara Sky V2/V3, Apres Nova), full-discharge the battery once per quarter to maintain the lithium-ion cell calibration.
- Annually: for the 96W-plus tier production-floor lamp, perform the full cure-time calibration check against a standard gel layer to confirm bead output. Replacement bead arrays are not field-serviceable, the lamp ships back to the manufacturer for the rare cure-time drift event.
Lamp troubleshooting and common failure modes
| Symptom | Likely cause | Fix action |
|---|---|---|
| Gel cures tacky on the surface | Under-cured: lamp wattage too low for gel formula, or timer set short | Increase cure time to 60s or upgrade lamp tier. Check the gel manufacturer's cure-time spec. |
| Gel chips at the cuticle within a week | Side-edge under-cure: lamp positioning too far above nail surface | Position lamp 1 to 1.5 inches above nail. Rotate hand 90 degrees mid-cure for full edge coverage. |
| Lamp does not power on | Timer or motion sensor circuit fault | Check power cord seating, then reset the timer button. For rechargeable models, plug into the charger for 20 minutes before retesting. |
| Cure time drift on older lamp | LED bead output degradation (rare for 50,000-hour-rated arrays) | Run the annual calibration check. If output is below 80 percent of original, lamp is end-of-life. |
| Battery does not hold charge (rechargeable) | Lithium-ion cell degradation | Full-discharge once, then full-charge. If cycle holds <50 percent of original runtime, battery is end-of-life. |
Bundle with gel collections to lift AOV
The lamp is the natural cross-sell with every gel collection ND ships. These are the pairings salons put together from this page and the gel pages (each item is its own listing; ND does not sell them as one boxed kit):
- Starter Kit: a LAVIS 2in1 lamp + Diamond Top + a magnet stick for cat eye gel, the salon-starter station.
- Cat Eye Pro Kit: a LAVIS 2in1 lamp + a multi-head magnet set + Diamond Top + Super Black gel, for the salon dedicated to cat-eye service.
- Chrome Kit: a 2-in-1 lamp + Chrome Powder + Chrome Base + Diamond Top, for the salon adding chrome service.
- Builder Gel Pro Kit: a Sun 5X Plus 108W lamp + a LAVIS Builder Gel set + Diamond Top, for the extension salon.
- Premium Mobile Booth Kit: a Kiara Sky Beyond Pro V3 + a dust collector + gel color sets, for the mobile-tier upscale salon.
Wholesale pricing at ND
ND ships every lamp tier at the wholesale-priced-for-everyone tier. No business license required, no minimum order, no membership fee. Free shipping on every order of $100 or more, same-day dispatch on in-stock lamps ordered before 2pm PT weekdays. The lamp category bundles into the gel collection orders at the volume-discount tier (10 to 25 percent off for orders of 30-plus units of any combination), which is the standard reorder cadence for the multi-chair salon stocking lamps plus gel together.
The LAVIS 2in1 line is the salon pick at ND because one plug-in lamp cures every gel system on the site, in a mid price tier with a choice of finishes. The Kiara Sky Beyond Pro V2 and V3, Apres Nova, Gelish 18 Light Unplugged, and Kupa Manipro Glo sit at the premium tier, where the rechargeable cordless ergonomics carry the price differential; the generic 96W cordless lamps give the no-cord format at the value tier.
