Any quotation is valid for a maximum period of 30 days from its date unless we expressly withdraw it at an earlier time. Use the helping hand to stabilise the bulb and and also to act as a heatsink on the bulb side of the stiff wires. The Goods will become your responsibility from the completion of delivery or Customer collection. You must, if reasonably practicable, examine the Goods before accepting them. Starting on the right hand side of the template and using the holes, solder a string of seven leds together. The long + lead on one led connects to the short – lead on the next led. Follow the polarity marked on the template. The power source is a 9 volt battery and this is boosted to 30 volts by an adjustable step-up switch mode boost module based on an XL6009 chip.

We can make changes to the Goods which are necessary to comply with any applicable law or safety requirement. We will notify you of these changes. The led heart consists of fourteen 2 volt leds in series which means that it needs a power supply greater than 28 volts. The leds are constant current devices that usually operate at 20mA. To reduce the heat in the light bulb and also to increase the life span of the leds it is a good idea to run them at a lower current level of 10mA. The light output from the leds at 10mA is more than enough and the heart effect is improved at lower light levels. RoHS Restriction of Hazardous Substances. Minimises the environmental impact of waste electrical and electronic equipment (WEEE) by reducing the quantities of four heavy metals and two brominated flame retardants. Specifies allowed limits of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE). If the base of the bulb comes apart from the glass during the grinding process then it can be reattached using epoxy adhesive. the party's obligations will be extended so far as is reasonable, provided that that party will act reasonably, and the party will not be liable for any failure which it could not reasonably avoid, but this will not affect the Customer's above rights relating to delivery.UKCA (UK Conformity Assessed) Meets UK health, safety & environmental protection directive requirements. If you or your nominee fail, through no fault of ours, to take delivery of the Goods at the Delivery Location, we may charge the reasonable costs of storing and redelivering them.

Glass is incredibly sharp and can fly some distance when it breaks, therefore careful handling of the bulb is necessary. Sales contract means a contract under which a trader transfers or agrees to transfer the ownership of goods to a consumer and the consumer pays or agrees to pay the price, including any contract that has both goods and services as its object. Disputes can be submitted to the jurisdiction of the courts of England and Wales or, where the Customer lives in Scotland or Northern Ireland, in the courts of respectively Scotland or Northern Ireland.Leds are fairly robust devices, but nonetheless you should try and avoid overheating them during the soldering process. To limit the current to 10mA, a 220 ohm resistor is placed in series with the leds and the supply voltage is set to 30 volts.

If we have not offered to collect the Goods, we will not make the reimbursement this is at customers' cost.

Solder a flexible wire to join the leds at the top of the heart

Using a rotary sanding attachment in a rotary tool, enlarge the top half of the hole until the copper tubing fits snugly.

In the case of any Goods made to your special requirements, it is your responsibility to ensure that any information or specification you provide is accurate.
