Not So Good In Direct Sunlight and Heat (Texas)

These did not bloom this first year at our Houston home.  Maybe better in cooler weather.

I gave this a three only because I am hoping they will make a bigger light!  I have a below ground pool and need light in the deep end. Live in Texas/Oklahoma  and it is hot as Hell here! We night swim as my pool water is already 89 degrees. Too hot for the day!

I have had these lights for a couple of weeks now.  I loved them at first.....because they were bright and fun patterns to pick from and we had some great weather days.  But soon as we had some cloudy days, the lights won't work.  These would be great if you have a southern exposure and/or live somewhere where the sun always shines.  I live in northern Iowa and we are hit and miss on the sunshine and I have a north facing condo so my lights don't get much direct sunlight and therefore will not work for days at a time.

Faded and flaked over a short period of time. Not good for cars or anywhere with direct sunlight and weather.

Beautiful next to our pool but it does fade with the direct sun in Arizona!  Been only 2 1/2 months, and it's very washed out in color.  The one under our two-person swing that has an attached umbrella is still vibrant.  Because it is advertised as Fade Proof and it's not, I'd stay away from purchasing this if it's going into direct sun light.

Delivery was timely and packaged securely.  I liked the wide beam, the greater coverage, and the smaller size with one of these bulbs versus the LED grow light bulb I had been using.  However, these bulbs are inadequate for my needs and my plants are not doing as well as under them compared to the other bulb.  I live in the desert and the outdoor temperatures can be excessively hot.  I have converted a portion of my home office into an indoor garden for growing fruits and vegetables.  It does not get adequate lighting, hence the need for the grow lights.  I considered getting a higher watt bulb but this 30W bulb generates a fair amount of heat.  I'm sure the IR bulbs contribute to this and would be useful in a colder environment.  I'm used to being able to touch the housing of the other bulb I have as it generates no discernible heat.  I burned my hand touching the housing on this bulb.  I can probably still use them for starting seedlings in the winter.  However, I will being buying more of the other bulbs.

I bought the 700 and installed it. When I plugged it in, the light on the plug-in device didn't come on. Tried it in my car and one other....I then started to drive out on the road during a sunny day and couldn't see the screen. I had to pull under an interstate highway overpass to read the screen in the shade. This may work well in clouds or the dark, but not well at all in the sun. Sent it back next day.

bought this hoping to replace an existing solar unit.
This unit even in direct sunlight in 98 degree west Texas sunlight barely beat the light breeze that was blowing. When I pointed into that same breeze the fan motor reversed.

A total waste of money. Was packaged back up and returned.

They don't stick very well in California sun. About 6 months and the tape deteriorated and needed to be re-applied

I live in NW Las Vegas Valley.  Spring is early here.  They have been in the ground now Two Weeks.  I used aged manure for the feriltizer, and have been watering as necessary.  Some of them have really started to green up and look quite healthy.  They are in the sun most of the day.  Others are still looking like winter (brownish) and are like still in hibernation.  They are the ones where shaded over 1/2 the day from direct sun.

Note will update when/if the ones in partial shade finally get up and go.  Finally note that we have lows in 50-60's and highs in 70's to 80's now ...

I bought these to hang lights up around our porch.  Strips didn't stand up the to the TX summer heat.  All fell down overnight and consequently broke all my lights.

They will sweat in humid climates, need to keep the bulb on at least half way to brightest setting to prevent a pool of water forming at the base.

problem is it doesn't stick for very long in the hot sun.

This item is way to light for AZ sun and heat. May work in mild weather areas but not here.

Works nicely with bright sunlight, but just drools or stops with less than full sun.  I have other solar powered items and this seems to be the weakest I have ever tried to use.  Sorry folks but that is the bottom line.

If you live a somewhere hot like Texas this product will heat up like an iron during the day. It was unbelievably not.

I am not happy with this product. I had them in the sun for the entire day and when it came time to use them they did not light up as bright as they should have.  Very very disappointed with the product.
