EcoTech Radion XR15 G6 PAR & PPFD Data
EcoTech Marine · Radion XR15 G6 · Reef
The figures below are compiled from public sources: EcoTech Marine’s own product page and reef-hobbyist PAR readings posted on Reef2Reef. They are not our own measurements. Each row says where the value came from, and where a number is a single hobbyist reading rather than a controlled test it is labelled that way.
EcoTech does not publish a numeric PAR grid
Unlike most grow-light vendors, EcoTech Marine does not publish a numeric PAR grid or PPFD map for the Radion XR15 G6. The official product page describes the light qualitatively — “ridiculously even PAR,” “incredibly even PAR over almost 4 ft of coverage” — and gives hardware specs, but no per-position µmol/m²/s numbers and no PAR-at-distance table. There is no manufacturer chart to transcribe for this fixture, so the grid tables that appear on our grow-light pages do not exist here.
What EcoTech does state:
| Metric | Manufacturer stated | Source |
|---|---|---|
| Power consumption | 95 W | ecotechmarine.com/radion |
| Input range | 100–240 VAC, 50/60 Hz | ecotechmarine.com/radion |
| LED count | 50 diodes (XR15 G6 Blue) / 52 diodes (XR15 G6 Pro) | ecotechmarine.com/radion |
| Light spread | 126.3° (up from 110.5° on the G5) | ecotechmarine.com/radion |
| Dimensions | 7 × 7 × 1.5 in (18 × 18 × 3.9 cm) | ecotechmarine.com/radion |
| Weight | 3.5 lb | ecotechmarine.com/radion |
| Coverage claim | ”even PAR over almost 4 ft” (qualitative, no number) | ecotechmarine.com/radion |
The spread figure is the only optics number EcoTech quantifies; the wider 126.3° cone is what the “even PAR” claim rests on. It says nothing about absolute intensity at a given height, which is the number a reefer actually needs.
Hobbyist PAR readings (no manufacturer figures exist)
Because EcoTech publishes no PAR numbers, the only quantitative data comes from reef hobbyists posting meter readings on Reef2Reef. These are single-point readings from mixed setups (different tanks, mounting heights, spectra, and meters), not a controlled grid, so they are useful as an order-of-magnitude reference only. We reproduce them with their stated conditions and label them unverified.
| Reading (µmol/m²/s) | Conditions | Status | Source |
|---|---|---|---|
| ~150 PAR | 12 in below surface, default AB+ schedule at 45% intensity, ~20 in spread radius | hobbyist-reported, unverified | Reef2Reef par-reading-xr15g6 |
| ~270 PAR | 20 in cube, XR15 G6 Pro, AB+ at 100%, top rocks ~15 in tall | hobbyist-reported, unverified | Reef2Reef radion-xr15-pro-g6-intensity-over-20g |
| ~350 PAR | Same 20 in cube after fitting the High Intensity (HEI) lens | hobbyist-reported, unverified | Reef2Reef radion-xr15-pro-g6-intensity-over-20g |
| ”in the 100s, little above 200” | XR15 G6 Pro alone, AB+ at 100%, light 10.5 in off water | hobbyist-reported, unverified | Reef2Reef par-rating-for-x15-g6-pro |
Two things recur across those threads and are worth stating plainly. First, the common AB+ schedule caps the non-blue channels (green, red, warm/cool white) at roughly 24% while the blues run at 100%, so a nominal “100% intensity” on AB+ is only about 75–78% of the fixture’s full output — reported PAR is not at the hardware ceiling. Second, several owners note the G6 reads lower PAR than the G5 at the same schedule because the new lens spreads light wider, which is why the optional High Intensity lens comes up so often for smaller, deeper tanks.

Notes
The honest summary for the XR15 G6 is that there is no manufacturer PAR grid to compare against, so the vendor-vs-measured contrast that anchors our grow-light pages cannot be drawn here. The usable takeaways are qualitative from EcoTech (95 W, 126.3° spread, even coverage to nearly 4 ft) and approximate from owners: expect roughly 150–350 PAR in the top third of a small-to-medium reef tank on the AB+ schedule, higher with the High Intensity lens, and remember the AB+ ceiling means “100%” is not the fixture’s true maximum. Anyone needing a real number for their own tank has to meter it — which is exactly the gap a phone-based estimate is meant to narrow.
