4w.
how long should a charge take and how do i know its full
Asked by roger on 4 Jan 2024
A USB charge should take between 6 and 8 hours, and the green indicator light will switch on (as opposed to red). Via solar charge, the light should take 3-5 days to charge to completion.
Can you get a longer cable to increase the distance from the solar panel to the battery pack?

Hi we bought a set of these last year.Anyway my husband in his wisdom remove the batteries pack for winter and now we can't find it. Can you buy a new battery pack. I'm just wondering because I've put the lights on an arch and I'm a little stressed and don't want to take them down as it's a lot of lights. These lights are fantastic and look great. Kind regards

The replacement is available to order on the Spare Parts tab in Your Account if the product is still within its 12-month warranty. If the warranty has expired on the product, the replacement is available to purchase under this link
Id like to wrap these around and along the length of chestnut fencing (20+ metres) but at the far end it is quite shady (solar panel might not get loads of light, how many hours is needed). The other end (near the house and drive) has a sunnier aspect but there are house security lights which are permanently on during the evening, plus there are vehicle lights frequently. Can you set the lights so that they automatically turn on in the evening regardless of whether there are other lights present? I'm looking at having them at the wedding next year, where there will be even more lighting present.
Asked by Sonia on 22 Aug 2021
If there is any light getting onto the panel then the lights will assume it is daytime, so will not work if the panel is plugged in. You do have the option of fully usb charging and then using them outside without the panel attached if you wanted to, however, this isn't an ideal permanent solution.
Can the solar panel be surface mounted, e.g. on a wall or garden fence.
Asked by S H Liddell on 25 Apr 2021
Yes, the panel can go on the wall on be installed using the spike provided.
Is the battery that is supplied, a protected or unprotected type. How long does the battery last (roughly) How much does the battery cost to replace (roughly) Regards Craig

Will these work with just solar power & not usb charged? We are looking for a solution for a village xmas tree we can no longer get 240v supply to.
Asked by Matt wallis on 3 Nov 2020
We strongly recommend charging in the first instance with USB charging, but if you place these on powersaving then they will run for you. Please do make sure that they are not near any other lights source in the evening or thye will not come on as they will assume it is day time.

My gardener has cut through the cable from solar panel to tube. Is it possible to buy a replacement part or do I have to replace the entire set?
Asked by Sandra Turnbull on 16 Sep 2020
You are able to buy replacement parts, just use our handy search bar for the Lumify string you need!
Can these lights switch on during daylight using battery/solar power? I am asking because there is no mains power where they are to be situated but would need to use them during daylight hours.
Asked by Dawn Vigurs on 14 May 2020
Yes, if you fully charge them and then unplug the panel it will run in the day time. Please remember to re-attach the panel after so it can charge or you can just recharge the USB tube.
Can the solar lights be switched on permanently instead of coming on at dusk? We would like to use them indoors but not when its dark.
Asked by shab on 1 May 2020
Yes, please do read the instructions on 'indoor mode' and this will help. All you need is the tube (not battery) and plug it into the wall without the panel attached.
Hi guys. If using these as Christmas light for 4 weeks of the year outside around then switched off the rest of the year would the solar panel keep the battery charged or would it cause damaged before the next Xmas came around.
Asked by Michael Scott on 1 May 2020
No, this will not damage the panel.

Asked by Sarah O'Brien on 14 Mar 2020
Sorry to hear that water has got into the tube. Please make sure that the tube is hung up by the hook on the cap, this will stop any ingress. The tubes can be found here

We want to install a small Christmas tree for our village an the main road will the lights activate beneath street lighting?
Asked by Brian on 28 Oct 2019
Yes, and No, the panel contains the sensor which switches to charge mode (lights off) and lights on mode. You may be able to position the solar panel at a location and an angle in which the street light doesn't hit it but you would need to test this yourself. Control pack to panel is 2 meters.

Asked by Christopher Evans on 17 Oct 2018
Approximately 10cm. Total length is 30meters, so really depends on how close you'd like each string of light.
I am looking at illuminating an outdoor 12ft Christmas tree. Will your 300 led solar USB lights do the job, or what do you recommend?

Asked by robert chappell on 3 Oct 2017
Cable ties tend to work well either with hocks or screws.
Hi Whilst removing my lights from the tree to trim it I have separated the cable wiring . Can I join them again and shorten them by one bulb will they still work safely provided I make watertight cable joints after soldering ?

Hi To charge by USB, do you need to remove the solar panel and tube (eg if hanging in tree outdoors) or just the tube itself? Wondering how accessible both need to be from the ground. Thanks
Asked by Anne on 12 Oct 2015
Just the tube part. The lights and solar panel can be unplugged from the tube.
Hi. I get that there is 2m between Solar Panel and Tube and another 2 metres between Tube and light string. How long is the light string? Thanks
Asked by D A Jack on 14 Sep 2015
There is 30m of lights after the initial 2m from control pack.
Does the 300 light version have a larger battery than the 100 light version. Just wondering about the run time.
Asked by Mark on 12 Sep 2015
It does. The 300 version has bigger batteries and a better solar panel to support the extra LEDs. Run time in both is about the same due to the increase.
