Reviews

"Set it up for my cat and he loves the extra heat when the sun goes down"

— James (5/5)

Great bulbs at a decent price

"I am so glad I found Therabulb before spending hundreds (or more!) on the same type of bulbs elsewhere! The independent, third-party testing is key, along with the fair price. These are the real deal without the hype."

— Jeanne A. (5/5)

"Their bulb arrived in perfect condition generates plenty of infrared heat. I think I need two more."

— Dan (5/5)

Amazing IRL Bulb

"This bulb is outstanding. I purchased to improve thyroid function, skin issues, and thinning hair. I do 20 minutes per day and it feels fantastic. I feel very relaxed using it and have started seeing results in the first week of use. I highly recommend it."

— Maggie W. (5/5)

Therabulb is great!

"I bought a clamp lamp and hung my Therabulb next to my easy chair. Not only has it calmed my arthritis and gouty knees, it is a great alternative to running a space heater here in Massachusetts where our energy bills have gone through the roof. Chicken-brooder jokes aside, my cat and I love to bask in its gentle warmth."

— Kim P. (5/5)

Excellent quality

"I have used several NIR bulbs in the past. These are the best quality and value on the market hands down. Will continue to buy in the future!"

— Casey P. (5/5)

Incandescent lamp

"Delivered on time and in good condition. Works well as expected. This is a repeat purchase. Very happy with the service. The LED lamp has not been used as yet. Can’t give a review."

— John G. (5/5)

Soothing

"Super soothing and relaxing. I lay under the bulb when I have a migraine"

— Natasha D. (5/5)
