LED Replacement Bulb and Ballast Units
These LED light tubes were created to meet the exact needs of plants. They deliver full-spectrum light with an additional spike of blue light to stimulate stronger root growth and enhance photosynthesis. Long-lasting LED tubes won’t shatter like glass bulbs and they're mercury-free so, unlike fluorescent bulbs, there's no need for special disposal. Each LED Replacement Unit contains 1 bulb and 1 ballast.
