ABI LED Light Bulb for Red Light Therapy, 660nm Deep Red, 54W Class

A good compromise for me on price and efficacy. You need to be close but it works in a normal lamp bulb socket. Wear eye protection!

The heat is intense, but feels good to the skin. Would recommend to keep warm and for other beauty regimes.

This is one very strong red light. Has its own little fan built in it. Worth the cost.

UPDATE from a not-electrician: Not the fault of the bulb, but rather a practical/logistical issue. A couple uses in - same lamp. So I managed to trip the circuit with this and the fireworks left a nice burnt pattern on my cream colored bedspread. So. Here's some free advice. This is a VERY HEAVY bulb to be screwed into a regular socket. When you put it in a downward-facing floor lamp (as is logical if you want to shine this on a body part while laying down) -- it will put considerable pressure on the socket (as per, uh, gravity). Today when I turned it on for my two minute routine, it didn't. Turn on. So I tried removing and replacing, etc. etc (a regular bulb worked so it wasn't the lamp....etc.) When I screwed this red light back in, I tried to tighten it securely (saw the socket shift inside the housing) and that's when the fireworks erupted. Fortunately the lamp socket is in a metal housing but even so, a few sparks flew out and landed on my bedspread, carpet, computer, etc. Yep. So that happened. My guess is the weight of the bulb facing downward, over night, meant the contacts were no longer tight in the socket? And when I tightened it, I created another problem by twisting the socket itself and wires touched that shouldn't touch? Don't know. HERE'S THE FREE ADVICE: 1) Whatever socket you are screwing this into -- abide by the annoying rules and disconnect the power first like an intelligent person. 2) But even more importantly, I will only screw this into a socket I can HOLD IN MY HAND (i.e., a handheld socket attached to a cord). Otherwise, you are screwing this VERY HEAVY LIGHT into a socket which, if not totally secure/stable, is going to rotate/shift/jiggle whatever -- beyond your control. When you add the weight of this bulb to the mix -- fireworks potential. From here on out, I think I'll only use this red light in handheld sockets that I can directly manipulate. Or. I might return it. Not sure. It was a wee bit scary. Again, not the fault of the bulb, but USE OF this bulb requires some forethought. I've seen others opine it is good to use in "any lamp" you have around the house. Not my experience. ********************************************************************************************************************************* Nice that they give the specs. Would be even better if this info was in the Amazon description..... Hope the info in pics helps others!

I like the size, doesn’t seem deep.

It was very powerful, and exactly what I desired

Its a good quality light but the 54 watt rating is a lie. Its actually 27 watts.

The bulb was so heavy that my lamp kept tipping over. Not for standard lamp, must get heavy duty lamp.
