#7 of 8 · Best pen-and-tray kit✓ Product photos checked Sep 7, 2026Real retailer photo, cut out. Label unedited.
Consider it. A tidy mainstream HP pen-plus-LED-tray kit — genuine whitening, but the cheaper Colgate pen nearly matches it. A real hydrogen-peroxide pen plus a rechargeable LED tray from a trusted brand, enamel-safe, with a repeatable ~10-minute ritual.

Why It Scores 8.0 — And The Label Line Behind Each Number
Whitening efficacy
35% of scoreA genuine hydrogen-peroxide pen from an established brand delivers real whitening over a multi-day course. It scores well on the active, but the efficacy comes from the peroxide, not the LED tray, and there's no ADA Seal or SKU-specific trial to lift it above the sealed Crest strip. Solid, mainstream peroxide whitening.
Sensitivity management
25% of scoreAn enamel-safe hydrogen-peroxide formula with short ~10-minute sessions keeps sensitivity moderate for most users — comparable to other mainstream peroxide pens. It's neither the gentlest nor the harshest here; standard peroxide comfort, without a dedicated desensitizing angle.
Ease of use + fit
20% of scoreThe pen application is easy, but the rechargeable tray adds charging, fitting, and holding the tray for the session — more steps than a simple strip or a brush-and-go pen, for whitening the tray doesn't actually provide. Tidy and repeatable, but fussier than the format needs to be.
Value per full course
15% of scoreThe weakest axis. At a ~$80 list price and roughly $4 per session, it's the priciest per use here, and it overlaps with the ~$22 Colgate Overnight Pen (#5) that delivers similar peroxide whitening. Value only holds up on the frequent discount; at list you're paying for the lamp.

Honesty of claims
5% of scoreThe active is a disclosed, genuine hydrogen-peroxide pen — credit for real chemistry from a mainstream brand. It loses points for building the kit around an LED tray that adds little beyond the gel, which implies more whitening power than the lamp delivers.

Marketing Claims Vs. Reality
Genuine hydrogen-peroxide pen from a trusted brand.
It's a real hydrogen-peroxide whitening pen from Colgate, an established oral-care manufacturer — the active is genuine and delivers real whitening (Carey 2014).
The rechargeable LED tray accelerates whitening.
As with every light kit here, independent reviews find blue-LED tray lights add little beyond the peroxide gel (Epple 2019); the tray mainly acts as a timer. The peroxide whitens — the lamp is an accessory, not the active.
Enamel-safe.
Hydrogen peroxide at consumer concentrations is enamel-safe used as directed (Carey 2014; Epple 2019); the short sessions keep exposure conservative.
Professional-level results.
Real HP whitening occurs, but 'professional' overstates an at-home pen, and the cheaper Colgate Overnight Pen (#5) delivers similar peroxide whitening for a fraction of the price — the LED tray doesn't add the professional edge implied.
Reusable — rebuy only the refill.
The tray hardware is reusable and you rebuy the pen refill — a genuine value note, though the ~$80 list price undercuts it unless bought on discount.
What Our Test Actually Found
Genuine whitening from a name you trust
This is a real hydrogen-peroxide pen from a mainstream oral-care brand, so the whitening is legitimate and the system feels tidy and professional. If brand trust and a repeatable ritual matter to you, that's the core appeal.
The LED tray is the accessory, not the active
Same story as every light kit here: independent reviews find the LED adds little beyond the gel, so the tray is essentially a timer. The peroxide does the whitening — don't buy this for the lamp, and don't pay the full list price for the glow.
The cheaper Colgate pen nearly matches it
The reason it lands at #7: the ~$22 Colgate Overnight Pen (#5) gives you very similar peroxide whitening for a fraction of the cost. Unless you specifically want the kit format, the overnight pen is the smarter buy from the same brand.
Buy it on discount, not at list
At ~$80 list and roughly $4 per session it's the priciest per use here; on the frequent ~$40 discount the value is far more reasonable. This is a wait-for-the-deal kit, not a full-price one.
Tidy, but fussier than it needs to be
Charging the tray, fitting it, and holding it through each session adds steps for whitening the tray doesn't provide. A strip or a brush-and-go pen is simpler for the same active — you're paying in convenience for a ritual, not for results.

- Genuine, disclosed active — real whitening chemistry
- The LED tray adds little beyond the gel — the peroxide does the whitening
- Priciest per session at list price; wait for the frequent discount
- Overlaps with the cheaper Colgate Overnight Pen (#5) that whitens similarly

- You'll buy it on the frequent discount rather than at ~$80 list
- You trust a mainstream oral-care brand and want reusable hardware

- You're paying for the LED tray expecting it to whiten — it's mostly a timer
A real hydrogen-peroxide pen plus a rechargeable LED tray from a trusted brand, enamel-safe, with a repeatable ~10-minute ritual. The honest problems: the LED tray adds little beyond the gel (it's a timer), it's the priciest per session at ~$80 list, and it overlaps heavily with the far cheaper Colgate Overnight Pen (#5). Genuine whitening — but buy it on discount, for the format, not the lamp.
The Colgate Optic White Pro Series kit is the safe, mainstream pen-and-tray option for buyers who want a branded system and a repeatable ritual. It pairs a genuine hydrogen-peroxide whitening pen with a rechargeable LED mouth tray, it's enamel-safe, and the ~10-minute sessions make a tidy at-home routine. The same caveat applies as to every light kit here: the tray's glow is mostly a timer — the peroxide is what whitens — so don't pay the full ~$80 list price for the lamp. It lands at #7 because the far cheaper Colgate Overnight Pen (#5) gives you very similar peroxide whitening for a fraction of the cost. Buy this if you specifically want the kit format from a name you trust, and buy it on the frequent discount rather than at list.
A genuine branded kit — worth it on discount and for the format, not for the lamp.

If This Doesn’t Fit — Try These
04Colgate Optic White Overnight Pen
The Colgate Optic White Overnight Pen is the value champion: real hydrogen-peroxide whitening for around twenty dollars.
05AuraGlow Teeth Whitening Kit
If you want the deepest at-home whitening and a full salon-style ritual, the AuraGlow kit delivers the strongest oxidizer dose on this list — 35% carbamide peroxide, which converts to a high effective hydrogen-peroxide load, held against the whole tooth by a tray.
01Crest 3D Whitestrips Professional Effects
If you want the most reliably effective at-home whitening and you don't want to gamble, Crest 3D Whitestrips Professional Effects is the default.
Quick Answers
Does the LED tray actually make my teeth whiter?
Barely, if at all. Independent reviews of the literature find blue-LED tray lights add little beyond the peroxide gel (Epple 2019) — the tray mostly functions as a timer for your session. The hydrogen-peroxide pen is what whitens, so don't pay the full list price expecting the lamp to do the work.
Why is this ranked below the cheaper Colgate pen?
Because the ~$22 Colgate Overnight Pen (#5) delivers very similar hydrogen-peroxide whitening for a fraction of the ~$80 list price, and the LED tray that justifies the premium adds little. Unless you specifically want the branded kit-and-ritual format, the plain pen is the smarter value from the same brand.
Is it worth buying at all?
On discount, yes — if you want a tidy branded system with reusable hardware and a repeatable ritual, it's a genuine hydrogen-peroxide kit and enamel-safe. At full ~$80 list it's the priciest per session here and hard to justify over cheaper options. Treat it as a wait-for-the-deal purchase.
Will it make my teeth sensitive?
Moderately, like most peroxide pens. The enamel-safe formula and short ~10-minute sessions keep sensitivity manageable for most users, but it has no dedicated desensitizing angle. If your teeth sting from peroxide, the peroxide-free PAP strips at #6 are the better sensitive-teeth choice.

The ADA confirms hydrogen peroxide is the bleaching agent that whitens teeth — supporting the genuine whitening from this kit's HP pen while underscoring that the whitening comes from the peroxide, not the accompanying light.
- [2] Carey 2014 PMID 24929591 — Tooth whitening: what we now know. Establishes hydrogen peroxide's efficacy and enamel safety at consumer concentrations and that whitening scales with the peroxide and contact time — the basis for scoring the pen's whitening on its gel rather than its LED tray.
- [3] Epple 2019 PMID 31374877 — A Critical Review of Modern Concepts for Teeth Whitening. Concludes that light activation, including LED units, contributes little beyond the peroxide gel — the direct evidence behind flagging the rechargeable LED tray as a timer rather than an active whitening component.
