The TheraTouch LX2 cluster and single-diode applicators offer different coverage patterns, not two grades of treatment. The cluster places multiple emitters over neighboring locations. The single diode gives the clinician a smaller treatment head for a selected point. Choose around the intended target, usable contact area, and approved protocol—not the largest total-power figure.
Our TheraTouch LX2 system with cluster applicator includes the standard cluster. Existing owners can order a replacement LX2 cluster or add the optional single-diode applicator without buying another complete system.

Cluster vs. single diode: the differences that matter
Both applicators connect to the LX2. Their emitter counts and published outputs differ, but neither operates as a standalone laser.

| Richmar reference | DQLLLT-CA | DQLLLT-SA |
| Emitter configuration | Five infrared laser diodes plus four red LEDs; nine emitters in total. | One laser diode. |
| Published wavelength | 850 nm laser component; 650 nm LED component. | 850 nm on Richmar's current product page. Its linked manual says 650 nm; see the verification note below. |
| Nominal optical output | 1,040 mW combined: five 200 mW lasers plus four 10 mW LEDs. | 200 mW. |

| Purchasing role | Included with the standard complete system; also sold as an applicator-only replacement. | Optional accessory, not included in the standard system configuration. |
The table follows Richmar's current LX2 product and accessory listing. Values describe rated output, not energy measured in a patient's tissue. Our applicator listings use store SKUs DQLLT-CA and DQLLT-SA; Richmar's references above contain an additional “L.” Match the full product description and confirm the reference when requesting a quote.
Confirm the single-diode wavelength before purchase or protocol matching. The operation manual (PDF) lists 650 nm for DQLLLT-SA on printed page 19, unlike the 850 nm product-page listing. We have not verified that this represents a hardware revision. Ask us to confirm the supplied applicator label and applicable instructions; do not combine specifications from the two sources or select protective eyewear on an assumption.
Start with the target and the available contact area.
Consider the cluster for a multi-point treatment region.
The LX2 cluster applicator can be useful when the plan calls for several neighboring sites and its treatment face can be positioned appropriately. One placement delivers light from multiple emitters rather than requiring a single probe to visit each of those locations separately.
That is a coverage advantage, not a guaranteed reduction in appointment length. Patient positioning, the planned pattern, cleaning, safety checks, and any device-required pause still take time. The cluster is not a uniform 1,040 mW beam filling every part of the applicator outline.
Consider the single diode for a smaller selected point.
The LX2 single-diode accessory offers a smaller head when the intended site or body contour makes the cluster less practical. A point-by-point plan may also benefit from identifying each placement separately.
Do not equate “small” or “focused” with a guaranteed deeper treatment. A diagnosis such as shoulder pain does not identify the required surface pattern or establish that either applicator is suitable. Our pain-management modalities guide explains how to separate an equipment capability from the outcome the clinician intends to evaluate.
Why 1,040 mW does not mean five times the dose at one point
The cluster's five laser diodes add up to 1,000 mW; its LEDs add 40 mW. A single cluster laser is rated at 200 mW, as is the optional single diode. The larger total therefore comes from multiple emitters, not a fivefold increase in each laser's rated power.
The example below applies energy = power × time to the published nominal outputs. Twenty seconds is chosen only to illustrate the arithmetic. It is not a recommended exposure, a measurement of a particular device, or a calculation of absorbed tissue dose.
| Quantity being compared | Cluster | Single diode |
|---|---|---|
| Total laser energy | 20 J | 4 J |
| Additional LED energy | 0.8 J | None listed |
| Combined emitted energy | 20.8 J | 4 J |
| Energy per laser diode | 4 J | 4 J |
Do not divide the cluster's combined joules by nine and call the result joules per laser diode. That would mix five lasers with four lower-power LEDs. Equal energy per laser diode also does not establish equal energy per square centimeter: the beam areas and treatment patterns must be considered.
The LX2 displays joules, J/cm², and J/diode. Published guidance on reporting laser dose and beam parameters emphasizes wavelength, beam area at the skin, power, exposure time, and pulse characteristics. Applicator casing dimensions alone do not supply all of those measurements.
When changing applicators, recheck the selected head and the resulting dose displays against the approved protocol. Do not copy a timer setting, divide the time by five, or assume the same total joules create an equivalent treatment. A specification sheet is not evidence that one head produces better clinical results.
Two connections do not mean both applicators run together
The LX2 manual, printed pages 11 and 13, explicitly prohibits simultaneous operation of both applicators. The two connections support selection of the connected head, not two concurrent laser treatments.
Owning both heads can broaden the available application choices, but it does not double the console's treatment capacity. A replacement applicator is also not a second complete treatment station. For departments sharing equipment and responsibilities, our long-term-care rehabilitation modalities guide addresses monitoring, cleaning, and care-team handoffs.
Choose the correct order: complete system, replacement, or add-on.
First establish whether the clinic already has a compatible LX2 console. Then compare what the order includes, rather than treating the lowest advertised amount as the price of a complete laser system.

The TheraTouch therapy cart is a separate accessory for equipment organization and mobility. It does not add a treatment channel or turn an applicator-only order into a working system.
Before purchasing, confirm the model and serial identification of an existing console, the requested head, its label and manual, package contents, and the approved service route. A generic connector resemblance does not establish compatibility with another TheraTouch or Vectra platform.
For documentation questions, our prescription and letter-of-medical-necessity guide distinguishes an equipment order from payment approval. It does not establish insurance coverage for this device or accessory.
Three checks before adding or replacing an applicator
- State the missing capability. Is the current problem an inaccessible small target, a need for multi-point coverage, or a damaged head? That determines whether to consider an add-on, a different applicator, or a service.
- Match the complete setup. Verify the console, applicator reference, wavelength label, and applicable instructions together. Resolve any documentation conflict before relying on the equipment for a protocol.
- Plan use and upkeep. Confirm operator training, protective eyewear, cleaning, permitted operating conditions, and maintenance. An additional head does not remove those requirements.
Contact our team for an LX2 product check with the existing model, applicator reference, and the information you need confirmed. A photograph of the equipment label can help; patient-identifying photographs or treatment records are not needed for an initial product inquiry.
The smaller probe does not remove laser-safety requirements.
The LX2 is a professional Class IIIb laser system. FDA laser-hazard guidance identifies an immediate eye hazard with direct viewing of Class IIIb beams. “Cold laser” is not a promise that eye exposure is harmless, and visible brightness is not a reliable safety test.
Follow the complete patient-screening and laser-safety instructions, including appropriate protective eyewear, controlled access, contact technique, and cleaning. The LX2 manual specifies direct contact without coupling agents. Stop for an adverse reaction or equipment fault and obtain the appropriate clinical or technical assessment. Do not improvise a gel, adapter, repair, or calibration.
This comparison does not select a dose, treatment site, or course of care. Those decisions belong to the treating professional and the instructions for the actual system.
Common questions before choosing an LX2 applicator
Does “9-diode cluster” mean nine infrared lasers?
No. Its nine emitters include five infrared lasers and four red LEDs. Keep the two components separate when interpreting total output or laser energy per diode.
Can I add the single diode after buying the complete LX2?
Richmar lists it as an optional LX2 accessory. Use our single-diode product listing to request the appropriate addition, with the console and wavelength checks above completed before use.
Should every clinic buy both heads?
Not automatically. The standard cluster may satisfy the clinic's approved application needs. Add another head when it addresses a specific requirement, not because it is described as more precise or because both ports are available.
Does the lower-powered head always need a longer treatment?
No universal conversion follows from the power ratio. Compare the required pattern, energy per point, beam area, and permitted settings. A broad multi-point application and a single-site application are not the same task.
Match the treatment pattern, then select the exact product.
For a new platform, review our LX2 system with the standard cluster. For an existing system, compare the cluster-only replacement and single-diode add-on against the confirmed requirement. Our laser therapy collection keeps devices and accessory options available for comparison.
The useful decision is not “which number is bigger?” It is whether the chosen head, documented specifications, and complete order support the intended clinical work.
