What to know before buying

The timer specifies 4/8/12-hour on periods and corresponding 21/18/12-hour off periods. The IP54 splash-resistance statement is a manufacturer claim and should not be taken to mean the light can be submerged.

Listing details to confirm

Listing details are inconsistent: the title says 2FT, while listed dimensions give a 67.49 cm long axis and 6.6 cm on the other two axes. The 195W-equivalent claim, 2600-lumen maximum and broad full-spectrum claim are listing claims, not independently confirmed; the listing also describes 4000K daylight. Confirm fit and the lighting details against your setup before buying.

Customer feedback highlights positive impressions of lighting quality, timer operation and results with house plants. That may matter to buyers looking for scheduled supplemental light, but customer impressions do not confirm the claimed 2600-lumen output or establish coverage for a specific plant area. Ratings are mostly five-star, with a smaller spread across lower categories, so experiences are not uniformly positive.

Frequently asked questions

Does this grow light have a built-in timer?

Yes. The listing describes 4-, 8- and 12-hour on settings with automatic off periods of 21, 18 and 12 hours, respectively.

Can the brightness be adjusted?

The listing says it has four brightness levels: 25%, 50%, 75% and 100%.

How should I interpret the stated 195W equivalent?

That is a listing claim for equivalent traditional-lighting output, not the fixture's electrical consumption. Its stated wattage is 25 watts.

What do customers report about it?

Customer feedback describes positive experiences with house-plant growth, lighting quality and the timer. Those reports do not establish output measurements or suitability for every plant and growing area.
