Which Viqua UV Lamp Do I Need? Match Your System to the Right Lamp and Sleeve

To find the right Viqua UV lamp, read the model number on the silver label of your system's stainless-steel UV chamber, then match it to the lamp and sleeve in Table 1. Older units may carry the Sterilight or UVMax name instead of Viqua. Viqua says to replace the lamp every year of continuous use, and to use only Viqua lamps in Viqua systems, because other lamps void all system certifications.

Find Your Viqua Model Number

Your Viqua model number is printed on the silver label on the UV system's stainless-steel chamber, according to Viqua. That number is the key to every table in this guide. Write it down before you look up any lamp or sleeve.

Where the label is on Viqua, Sterilight and UVMax units

On Viqua, Sterilight and UVMax units, the model label is the silver label on the stainless-steel UV chamber. Viqua notes that older units may say UVMax or Sterilight rather than Viqua. The lamp and sleeve sit inside that same chamber.

If the label is missing: use the controller, manual or Viqua's finder

If the model label on your UV chamber is missing or unreadable, check the system manual or enter what you know into Viqua's replacement lamps and parts finder on viqua.com. If your model isn't in this guide's tables, use Viqua's finder rather than guessing. A lamp that doesn't match your system won't fit or won't carry Viqua's certifications.

Viqua Lamp and Sleeve Finder by System

Each Viqua UV system uses one specific lamp and one specific quartz sleeve, and Viqua's product pages list which systems each part fits. Tables 1 and 2 copy that compatibility from viqua.com. Several systems share a lamp because Viqua sold the same chamber under different names.

Home series: VH150, VH200, VH410

The Viqua VH150 uses the S150RL-HO lamp, the VH200 uses the S200RL-HO, and the VH410 uses the S410RL-HO, according to Viqua. For the VH200 and VH410, Viqua also sells a combo pack with the lamp and sleeve together: the QL-200 and QL-410. You can find these systems among DFS's Viqua range.

Professional and high-flow: VP600, VP950, SHF series

The Viqua VP600 uses the S600RL-HO lamp, the VP950 uses the S950RL-HO, and the SHF-140 uses the S740RL-4C, according to Viqua. The VP600 also has a combo pack, the QL-600. Viqua lists the QSO-950 sleeve for the VP950 and VP950M.

Table 1 maps each current Viqua system to its lamp, sleeve and combo. Find your model in the first column, including the older names listed in brackets.

Table 1. Viqua System to Lamp, Sleeve and Combo (Current Series)

Viqua lists the QS-001 sleeve for the VH200, S1Q-PA and SSM-14, and the QSO-410 sleeve for the VH410. For the older names in brackets, confirm the sleeve on its viqua.com product page.

Sterilight S-Q-PA and SSM systems

Sterilight S-Q-PA and SSM systems use the S212RL, S330RL, S463RL or S810RL lamp, depending on the model, according to Viqua. For example, the S5Q-PA and SSM-24 use the S463RL lamp and QS-463 sleeve. Match your Sterilight model in Table 2.

Legacy UVMax Letter Series (C, D, E, F, G, H, J, K)

Legacy UVMax letter-series systems use Viqua's six-digit lamps, from 602805 for the C and D family to 602856 for the J and K family. Each lamp has a matching six-digit sleeve. Table 3 lists them by system.

UVMax C/D/E/F lamps: 602805, 602806, 602807

UVMax C and D family systems use the 602805 lamp, E family systems use the 602806, and F family systems use the 602807, according to Viqua. Their sleeves are the 602732, 602733 and 602734. Some PRO models share these lamps, such as the PRO7 with the 602806.

UVMax G/H/J/K and PRO lamps: 602854, 602855, 602856

UVMax G, H, J and K systems use the 602854, 602855 or 602856 lamp, depending on the model, according to Viqua. The matching sleeves are the 602974, 602975 and 602976. If you have an IHS unit, check its label and use Viqua's finder.

Table 3 groups each UVMax system with its lamp and sleeve.

Lamp, Sleeve or Combo Pack: What to Order

Order a lamp alone if your quartz sleeve is clean and undamaged, or a QL combo pack if you also need a new sleeve. A Viqua QL combo pack contains the lamp and the quartz sleeve for one system series. The sleeve is cleaned at every lamp change and replaced if scratched or cracked.

When a QL combo pack makes sense

A Viqua QL combo pack makes sense when the quartz sleeve is scratched, cracked or won't come clean at the lamp change. Viqua confirms the QL-200 for the VH200 series, the QL-410 for the VH410 series and the QL-600 for the VP600 and VPM600. For other combos, confirm compatibility on the combo's product page before ordering.

If your sleeve is in good shape, a lamp alone is enough. Browse all DFS options under UV bulb replacement.

Sensors and controllers are separate parts

Viqua part 650703 is a replacement UV sensor, not a lamp, so it won't replace a burned-out or expired bulb. It's easy to confuse with the six-digit 6028xx lamps. Table 4 shows what the 650703 fits.

Table 4. Not a Lamp: Sensor Parts

Lamp Life, Alarms and OEM-Only Lamps

A Viqua lamp should be replaced every year of continuous use, and Viqua rates its VH200 and VH410 lamps at 9,000 hours. Viqua also says to use only Viqua lamps in its systems.

How long a Viqua lamp lasts

A Viqua lamp lasts about one year of continuous use, and Viqua rates the VH200 and VH410 lamps for 9,000 hours. Replace it on that schedule even if it still lights, because its output fades while it keeps glowing. Third-party lamps may claim longer life, but Viqua rates its lamps at 9,000 hours.

What the replace-lamp alarm means

A replace-lamp alarm on a Viqua controller means the lamp has reached its rated life and is due for replacement. Order the lamp listed for your model in Tables 1–3. After installing it, reset the lamp timer by following your system's manual.

Why Viqua says to use only Viqua lamps

Viqua says to use only a Viqua lamp in Viqua UV systems, because a non-Viqua lamp voids all system certifications. Keep that in mind before buying a compatible lamp from another maker. If you're replacing the whole system instead, compare models in our UV water purifier collection.

Frequently Asked Questions

What lamp does the Viqua VH200 use?

The Viqua VH200 uses the S200RL-HO lamp and the QS-001 quartz sleeve, according to Viqua. Viqua also sells the QL-200 combo pack, which contains the lamp and sleeve for the VH200 series. The S200RL-HO also fits the SC-200, SCM-200, SPV-200, SP200-HO and SPV-3.5.

What lamp does the Viqua VH410 use?

The Viqua VH410 uses the S410RL-HO lamp and the QSO-410 quartz sleeve, according to Viqua. The QL-410 combo pack includes both for the VH410 series. Viqua lists the S410RL-HO for the VH410M, SC-410, SCM-410, SPV-410, SP410-HO and SPV-8 as well.

Is the Sterilight S463RL the same as a VH410 lamp?

No, the Sterilight S463RL is not the VH410 lamp; Viqua lists the S463RL for the S5Q-PA and SSM-24. The VH410 uses the S410RL-HO. Check the silver model label on your chamber to confirm which system you have before ordering.

What is the difference between 602805 and 650703?

The Viqua 602805 is a UV lamp, while the 650703 is a replacement UV sensor. The 602805 lamp fits UVMax C and D family systems. The 650703 sensor fits the D/D4 PLUS, E/E4 PLUS, F/F4 PLUS, PRO7 and PRO15, and it does not replace a lamp.

Do I need to replace the quartz sleeve with every lamp?

No, you don't need a new quartz sleeve with every lamp, but Viqua says to clean it whenever the lamp is changed. Replace the sleeve if it's scratched, cracked or won't come clean. In that case, a QL combo pack gives you both parts in one order.
